Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart glasses often require manual operation of a reset button to perform hardware reset, which is inconvenient and can disrupt the aesthetic appearance, and they cannot automatically perform hardware reset.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a reset button is disposed on the glasses to enable hardware reset, then the glasses can perform hardware reset, but the aesthetic appearance of the glasses is destroyed and manual operation is required
Solution Approach 1:
The reset button is extracted from the glasses body and relocated to the charging case. The charging case now contains both the reset button and the wireless charging transmitter circuit. When the glasses are placed in the charging case, the reset function is accessible through the case rather than requiring a button on the glasses themselves, thus preserving the aesthetic appearance of the glasses while maintaining hardware reset capability.
Solution Approach 2:
The charging case serves as an intermediary device that provides the reset function. Instead of having the glasses directly provide the reset button, the charging case acts as a mediator that can trigger the reset of the glasses when they are placed inside. This intermediary approach allows the glasses to remain button-free while still enabling hardware reset through the charging case.
2Ease of operation
If a reset button is disposed on the glasses to enable hardware reset, then the glasses can perform hardware reset, but automatic hardware reset cannot be achieved
Solution Approach 1:
The system enables automatic hardware reset through self-service mechanisms. The charging case includes a processor that can automatically detect when the glasses require a hardware reset (such as when the chip runs unsteadily) and automatically trigger the reset sequence without requiring user intervention. The wireless charging transmitter circuit in the charging case can send signals to the glasses to initiate the reset process automatically.
Solution Approach 2:
The system implements feedback mechanisms where the processor in the charging case monitors the operational status of the glasses. When abnormal conditions are detected (such as unstable chip operation), the system receives feedback about the glasses' state and automatically responds by triggering a hardware reset through the wireless charging transmitter circuit, creating a closed-loop control system that enables automatic reset functionality.
3Ease of operation
If manual operation of reset button is required to perform hardware reset, then hardware reset can be performed, but user experience is poor
Solution Approach 1:
The system enables automatic hardware reset through self-service mechanisms. The charging case includes a processor that can automatically detect when the glasses require a hardware reset (such as when the chip runs unsteadily) and automatically trigger the reset sequence without requiring user intervention. The wireless charging transmitter circuit in the charging case can send signals to the glasses to initiate the reset process automatically.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring the operational status of the glasses and preparing to trigger a reset before problems escalate. The processor in the charging case detects early signs of instability in the glasses' chip operation and proactively initiates a hardware reset to prevent complete system failure, thereby improving user experience by addressing issues before they become problematic.
