Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional male-female type charging connectors are used, then reliable electrical connection is achieved, but precise alignment is required which reduces ease of operation
Solution Approach 1:
The patent replaces the conventional mechanical male-female connector system with a contactless charging system using electromagnetic induction. The charging case contains a charging coil that generates an electromagnetic field to wirelessly transfer power to the eyewear device, eliminating the need for physical alignment of connectors.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary between the charging case and the eyewear device. The charging coil in the case generates an electromagnetic field that couples with a receiving coil in the eyewear device, enabling power transfer without direct physical contact or precise alignment.
2Reliability
If precise alignment is required for charging connectors, then reliable contact coupling is achieved, but device complexity increases
Solution Approach 1:
The patent eliminates the mechanical alignment requirements by replacing the mechanical connector system with an electromagnetic coupling system. The charging coil and receiving coil arrangement allows for flexible positioning while maintaining reliable power transfer through electromagnetic field coupling.
3Duration of action of moving object
If regular connection to charging outlet is required, then battery recharging is achieved, but user satisfaction decreases
Solution Approach 1:
The patent replaces the conventional mechanical connection to charging outlets with a contactless electromagnetic charging system. The charging case with its integrated charging coil provides convenient wireless recharging when the eyewear device is placed in the case, improving user satisfaction by eliminating the need for regular manual connection to charging outlets.

AI summary
A carry case for an electronics-enabled eyewear device, such as smart glasses, has charging contacts that are movable relative to a storage chamber in which the eyewear device is receivable. The charging contacts are connected to a battery carried by the case for charging the eyewear device via contact coupling of the charging contacts to corresponding contact formations on an exterior of the eyewear device. The charging contacts are in some instances mounted on respective flexible walls defining opposite extremities of the storage chamber. The contact formations on the eyewear device are in some instances provided by hinge assemblies that couple respective temples to a frame of the eyewear device.
