Solution Overview

Problem

Wearable devices like smart glasses face issues with unstable chip performance, requiring manual hardware reset through a button, which affects user experience and aesthetics.

Innovation Solution

A glasses case equipped with a distance detection module and a wireless charging system that automatically triggers a power-on reset of the smart glasses when placed within a certain proximity, eliminating the need for a physical reset button.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a reset button is disposed on the glasses, then the glasses can perform hardware reset, but the aesthetic appearance of the glasses is destroyed

Engineering Contradiction:
Improvehardware reset capabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The reset button is extracted from the glasses body and relocated to the glasses case. The glasses case includes a reset button that can trigger a hardware reset of the glasses when the glasses are placed in the case, thereby eliminating the need for a physical button on the glasses themselves while preserving the reset functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a reset button is disposed on the glasses, then the glasses can perform hardware reset, but the user experience is poor due to manual operation requirement

Engineering Contradiction:
Improvehardware reset capabilityVSAvoiduser experience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system enables automatic hardware reset without requiring manual button pressing. When the glasses are placed in the glasses case, the reset button in the case automatically triggers a hardware reset of the glasses, making the device self-service capable and improving user experience by eliminating the need for manual intervention.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If automatic hardware reset is implemented, then the user experience is improved, but the device complexity increases

Engineering Contradiction:
Improveautomatic reset capabilityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The reset functionality is merged into the glasses case rather than being a separate component. The glasses case integrates the reset button and the control logic to automatically trigger hardware reset when glasses are placed in the case, combining multiple functions (storage, charging, and reset) into a single device and avoiding additional complexity on the glasses themselves.

Inventive Principle:
Principle #5Merging (Combining)
