In order to achieve this objective, the present invention moves a charging coil (8) from a charging position to a standby position by means of motors (28, 33) when charging is complete, or when charging is discontinued. The speed when the charging coil (8) is thus moved from the charging position to the standby position is lower than when the charging coil (8) is moved from the standby position to the charging position, and operating noise at the time can be minimised."},"analysis":{"summary":"The Mobile Terminal Charging Device, and Vehicle Using Same patent introduces a groundbreaking solution to a common automotive inconvenience: the noise generated by in-vehicle mobile device chargers. At its core, this innovation aims to significantly reduce user discomfort by intelligently managing the movement of a charging coil within a vehicle.\n\nThe primary problem this patent addresses is the audible mechanical noise produced when a charging coil moves, particularly when a charging session concludes or is interrupted. Existing systems often move components at a uniform speed, leading to noticeable sounds that can detract from the quiet ambiance of a vehicle's interior.\n\nThe key technical approach involves a movable charging coil (8) that transitions between a 'charging position' and a 'standby position'. This movement is precisely controlled by dedicated motors (28, 33). The critical differentiator, however, is the variable speed control applied to these movements. Specifically, the speed at which the charging coil retracts to its standby position is deliberately lower than the speed at which it deploys to the charging position. This optimized speed differential ensures that operating noise during the retraction phase is minimized, making the process virtually imperceptible to the user.\n\nFrom a business perspective, the Mobile Terminal Charging Device, and Vehicle Using Same offers substantial value. It provides automotive manufacturers with a compelling competitive advantage, allowing them to offer a more refined and premium in-cabin experience. By eliminating a subtle source of noise and enhancing overall user comfort, this technology aligns with the growing demand for sophisticated, unobtrusive vehicle interiors. Potential applications extend beyond passenger cars to RVs, public transport, and even aircraft, where noise reduction is highly valued.\n\nThis patent taps into a significant market opportunity driven by the increasing integration of personal electronics into vehicles and the ongoing pursuit of superior user experience. It positions itself as an essential component for next-generation vehicle designs that prioritize comfort, quietness, and seamless technological integration, promising enhanced customer satisfaction and differentiation in a crowded market.","layman_explanation":"### What Problem Does This Solve?\nImagine you're driving a brand-new luxury car. Everything is quiet, smooth, and refined. Then, you place your phone on the wireless charger, and a moment later, when it's fully charged or you pick it up, there's a distinct 'whir' or 'click' as the charging mechanism disengages. It's a minor annoyance, but it subtly detracts from the premium experience. This patent, called the **Mobile Terminal Charging Device, and Vehicle Using Same**, addresses exactly this problem: the audible mechanical noise generated by in-vehicle mobile device chargers. Existing solutions often move their internal components at a uniform, and sometimes abrupt, speed, which can create unwelcome sounds that clash with the meticulously engineered quietness of a modern vehicle cabin.\n\n### How Does It Work?\nAt its core, this innovation involves a charging coil that isn't static but rather moves into position when needed and retracts when not. Think of it like a hidden compartment in your car that slides open and closed. The clever part of this patent, however, isn't just the movement itself, but *how* it moves. The Mobile Terminal Charging Device, and Vehicle Using Same uses small motors to control the charging coil. When you place your phone, the coil extends to the 'charging position' to power up your device. But the real genius is when charging is complete or you decide to stop. Instead of snapping back quickly, this system is designed to move the coil back to its 'standby position' at a *much slower and gentler speed*. This deliberate slowdown during retraction is the key. By moving more slowly, the mechanical components generate significantly less noise, making the entire process nearly imperceptible to the occupants. It’s about creating a 'soft landing' for the mechanism, ensuring tranquility.\n\n### Why Does This Matter?\nThis innovation matters significantly for several reasons, especially in the automotive industry. First, it offers a crucial **competitive advantage** for car manufacturers. In a market where luxury and user experience are paramount, eliminating even subtle irritations like charging noise can be a powerful differentiator. It allows brands to deliver a truly seamless and refined in-cabin experience, aligning with the expectations of high-end consumers. Second, it enhances **perceived quality**. When technology operates silently and unobtrusively, it feels more advanced and polished. This can translate into higher customer satisfaction and brand loyalty. Third, it opens up **new market opportunities** in areas where noise reduction is critical, such as electric vehicles (where other noises are already minimal), autonomous vehicles (where the cabin becomes a multi-functional space), or even public transport and aircraft. The ability to provide a premium, quiet charging experience can justify higher price points and increase profitability.\n\n### What's Next?\nThe principles behind the Mobile Terminal Charging Device, and Vehicle Using Same are likely to influence the design of future in-vehicle electronics beyond just charging. We could see similar 'quiet retraction' mechanisms applied to other movable components, like retractable screens, cup holders, or even dashboard elements. As vehicles become increasingly sophisticated and integrated, the demand for technology that is not only functional but also elegantly 'invisible' will continue to grow. This patent sets a new standard for how mechanical systems can be designed to prioritize user comfort and acoustic refinement, paving the way for even more serene and technologically advanced mobile environments.","technical_analysis":"The patent **Mobile Terminal Charging Device, and Vehicle Using Same** (US-9853484) presents a refined solution for in-vehicle mobile terminal charging, specifically targeting the reduction of user discomfort caused by operational noise. The core technical ingenuity lies in its differentiated speed control mechanism for the charging coil's movement.\n\n**Technical Architecture:**\nAt the heart of this system is a movable charging coil (8) integrated within the vehicle's interior, likely within a console or dashboard. This coil is physically actuated by a set of motors (28, 33). These motors are not merely on/off switches but are part of a more sophisticated control loop that manages their speed and position. A central control unit (not explicitly numbered but implied by the motor control) would be responsible for processing inputs from charging sensors (detecting device presence, charging state, completion) and potentially user commands.\n\n**Implementation Details & Algorithm Specifics:**\nWhen a mobile terminal is placed on the charging area, the control unit detects its presence and the need for charging. It then instructs the motors (28, 33) to move the charging coil (8) from its standby position to the charging position. This movement can occur at a relatively higher speed, as the initiation of charging often coincides with the user placing their device, and a quick engagement might be perceived as efficient rather than intrusive.\n\nThe critical aspect, however, comes when charging is complete or discontinued. This could be triggered by the mobile terminal signaling a full charge, the user removing the device, or the vehicle being turned off. Upon receiving such a signal, the control unit initiates the retraction of the charging coil (8) back to its standby position. The patent explicitly states that the speed of this retraction is *lower* than the deployment speed.\n\nThis implies a specific velocity profile implemented by the motor control algorithm. For deployment, a typical trapezoidal velocity profile might be used, allowing for rapid acceleration, constant velocity, and deceleration. For retraction, the algorithm would employ a modified profile: a gentler acceleration, a significantly lower constant velocity, and a more gradual deceleration phase. This 'soft landing' or 'slow retraction' mechanism directly translates to reduced kinetic energy dissipation and minimized transient acoustic events, such as clicks, whirs, or thuds, typically associated with mechanical movements.\n\n**Integration Patterns:**\nThis device would integrate seamlessly with the vehicle's existing power management and infotainment systems. The charging status sensor could communicate via CAN bus or LIN bus to the vehicle's central gateway. The motors themselves would likely be controlled via PWM (Pulse Width Modulation) signals from the dedicated control unit, allowing for precise speed and torque regulation. Positional feedback (e.g., from Hall effect sensors or encoders integrated with motors 28, 33) would ensure accurate positioning of the coil and confirm its fully retracted or extended state.\n\n**Performance Characteristics:**\n*   **Acoustic Performance:** The primary performance metric enhanced by this patent is the acoustic signature. By reducing retraction speed, the peak noise levels and perceived harshness are significantly lowered, contributing to a premium cabin experience.\n*   **Reliability & Durability:** Slower, more controlled movements can also reduce mechanical stress on the motors and the coil's actuation mechanism, potentially increasing the system's longevity and reliability.\n*   **Energy Efficiency:** While not explicitly stated, optimized motor control for speed could also lead to more efficient power consumption, though the primary focus remains noise reduction.\n\n**Code-Level Implications:**\nImplementing this would involve firmware development for the control unit. Key components would include:\n*   **State Machine:** Managing charging states (idle, detecting, charging, complete, discontinued, retracting, deployed).\n*   **Motor Driver Interface:** Low-level control of motor drivers (e.g., H-bridge, stepper motor drivers).\n*   **PID Control (or similar):** For precise speed and position control of the motors, especially during the critical low-speed retraction phase.\n*   **Sensor Fusion:** Interpreting data from multiple sensors (charging status, positional feedback) to inform the state machine and motor control.\n\nThis patent represents an intelligent application of mechatronics and control theory to solve a user experience problem, demonstrating a pathway for future in-vehicle systems to be not just functional, but also aesthetically and acoustically refined.","business_analysis":"The **Mobile Terminal Charging Device, and Vehicle Using Same** patent (US-9853484) is a strategic innovation poised to significantly impact the automotive sector, particularly in the premium and luxury vehicle segments.
