Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smart glasses are charged using a mobile battery charging bank, then charging portability is improved, but charging connection stability deteriorates
Solution Approach 1:
The retention bracket is designed to be movable during insertion but becomes fixed when engaged with the nose bridge, dynamically adapting to the insertion process while ensuring stable contact during charging. This allows the system to transition from a mobile/portable state to a stable/secure state automatically.
Solution Approach 2:
The retention bracket acts as an intermediary component between the charging case and the smart glasses, specifically engaging with the nose bridge to provide mechanical stability. This intermediary structure enables portable charging while maintaining connection stability through its engagement mechanism.
2Reliability
If smart glasses are held securely in the charging case, then charging stability is improved, but device mobility deteriorates
Solution Approach 1:
The retention mechanism is segmented into distinct functional parts: the retention bracket that engages with the nose bridge, the resistance force component that provides holding pressure, and the release mechanism. This segmentation allows the system to provide secure holding during charging while enabling easy removal when mobility is needed.
Solution Approach 2:
The retention bracket applies a resistance force that prevents accidental disconnection during charging. This preliminary anti-action counteracts any forces that might cause the glasses to move or disconnect, ensuring charging stability without permanently restricting mobility.
3Ease of operation
If the charging case includes a battery for portable charging, then charging convenience is improved, but case size increases
Solution Approach 1:
The retention bracket and resistance force mechanism are nested within the charging case structure, utilizing the existing case volume efficiently. The battery is integrated into the case design with the retention components, creating a compact nested arrangement that minimizes overall case size while providing portable charging functionality.
