Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices without physical buttons face challenges in resetting when their operating systems malfunction, as they cannot receive input through software buttons, and battery-embedded devices cannot be reset until the battery is discharged.
Innovation Solution
A method for keyless reset is implemented using an external power supply device that communicates with the electronic device to perform a hardware or software reset through voltage changes and interrupt signals, allowing the device to be reset even when the operating system is malfunctioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical buttons are omitted from the electronic device, then the device size is reduced and waterproof performance is improved, but the device cannot be reset when the operating system malfunctions
Solution Approach 1:
The patent introduces an external power supply device as an intermediary to perform reset operations. The external power supply device communicates with the electronic device and can issue reset commands through voltage changes and interrupt signals, enabling reset functionality without requiring physical buttons on the device itself.
Solution Approach 2:
The patent replaces the mechanical button system with an electrical/electronic reset mechanism. Instead of using physical buttons that require holes in the housing, the system uses voltage changes and interrupt signals transmitted through the power supply connection to trigger reset operations, substituting mechanical input with electrical signaling.
2Volume of moving object
If physical buttons are omitted to reduce device size, then portability is improved, but the device cannot receive input when the operating system is malfunctioning
Solution Approach 1:
The external power supply device serves as a mediator that can interact with the electronic device even when the operating system is malfunctioning. Through the power supply connection, it can deliver reset signals that bypass the need for functional software input interfaces, allowing recovery from system failures.
Solution Approach 2:
The patent separates the reset functionality from the main device body by implementing it in the external power supply device. This segmentation allows the reset capability to exist independently of the device's own input systems, ensuring that reset functionality remains available even when the device's operating system fails.
3Device complexity
If software buttons are used to replace physical buttons, then device complexity is reduced, but the device cannot be reset when the operating system is in a malfunctioning state
Solution Approach 1:
The patent replaces software-based button input with hardware-level electrical signaling for reset operations. The external power supply device uses voltage changes and interrupt signals that operate at the hardware level, bypassing the need for functional software input processing, thus enabling reset even when the operating system is malfunctioning.
Solution Approach 2:
The external power supply device acts as an intermediary that provides reset functionality independent of the device's software state. By communicating through the power supply connection and using electrical signals rather than software interfaces, it can trigger resets even when the operating system is in a malfunctioning state.
