Keyless Device Tray Power Control Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Keyless electronic devices without physical buttons pose a challenge for users to forcibly power off or reset the device, as they cannot perform a hard reset or power off operation, leading to increased user inconvenience and reliance on battery drain or professional assistance.
Innovation Solution
An electronic device design featuring a housing with a socket for a tray that holds cards, a power management circuit, and a movable terminal that changes state upon tray insertion or removal, allowing the power management module to control power supply to internal components based on detected signals, enabling power cutoff or reset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If physical buttons are removed to create a keyless electronic device, then the device achieves a more compact and modern design, but the ability to perform forced power off or reset operations is lost
Solution Approach 1:
The tray, originally designed solely for holding cards, is given multiple functions: it serves as both a card holder and a power control mechanism. When inserted into the socket, the tray mechanically actuates the movable unit to generate electrical signals that control power supply, enabling forced power off/reset functionality without requiring separate physical buttons
Solution Approach 2:
The movable unit acts as an intermediary between the tray insertion action and the power management circuit. It converts the mechanical motion of tray insertion into electrical signals through the first terminal, bridging the gap between user input and power control in keyless devices
2Shape
If keyless design is implemented without physical buttons, then the device achieves better aesthetics and compactness, but user convenience for emergency power control deteriorates
Solution Approach 1:
The tray is transformed from a single-function card holder into a multi-functional component that also serves as a power control interface. Users can perform forced power off or reset operations by simply inserting or removing the tray, maintaining aesthetic simplicity while restoring essential power control capabilities
3Extent of automation
If no physical buttons are provided, then the device achieves a more sophisticated keyless interface, but the ability to perform hard reset operations is eliminated
Solution Approach 1:
The system uses the tray insertion/removal action itself to generate the power control signals through the movable unit and first terminal. This self-service mechanism eliminates the need for separate hard reset buttons while maintaining reliable power control functionality through the existing tray operation
