Smart Glasses Temple Charging Layout for Battery Extrusion Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart glasses batteries face safety risks due to extrusion stress during charging, which can lead to short circuits and potential explosions, limiting their continuous wearability and safety.
Innovation Solution
The smart glasses design includes a charging assembly and battery disposed at an interval, with a gap between them to buffer deformation and prevent direct contact, along with a supporting structure to limit movement and reduce stress, enhancing safety and battery capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the charging assembly is disposed close to the battery to save space, then the device compactness is improved, but the battery safety deteriorates due to extrusion stress during charging
Solution Approach 1:
The patent pre-establishes a gap between the charging assembly and battery before charging occurs, and provides buffer structures (elastic components, cushioning materials) in advance. This preliminary arrangement prevents direct contact and extrusion stress during charging, allowing the components to be disposed close together while maintaining battery safety
Solution Approach 2:
The patent introduces intermediary elements (elastic components, cushioning materials, buffer structures) between the charging assembly and battery. These intermediaries absorb deformation and prevent direct contact, enabling close disposal of components without compromising battery safety during charging
2Duration of action of moving object
If the battery capacity is increased to extend continuous wear time, then the duration of action is improved, but the risk of safety issues increases due to higher energy density
Solution Approach 1:
The patent pre-establishes protective gaps and buffer structures between the battery and charging assembly before charging. This preliminary safety arrangement allows the use of higher capacity batteries with higher energy density, extending continuous wear time while maintaining safety through pre-configured protection mechanisms
Solution Approach 2:
The patent introduces buffer structures and elastic components as intermediaries between the battery and charging assembly. These intermediaries protect high-capacity batteries from extrusion stress during charging, enabling the use of larger batteries that extend continuous wear time without proportionally increasing safety risks
3Ease of operation
If the charging assembly is allowed to deform during charging to accommodate connection, then the ease of operation is improved, but the probability of contact with battery increases
Solution Approach 1:
The patent pre-configures buffer structures and elastic components in the charging assembly that allow controlled deformation during charging connection. This preliminary design enables the charging assembly to deform for easy connection while the buffer structures prevent excessive deformation that would cause battery contact
Solution Approach 2:
The patent introduces elastic components and cushioning materials as intermediaries within the charging assembly. These intermediaries allow the charging assembly to deform during connection for ease of operation, while simultaneously preventing the deformation from transmitting to the battery, maintaining reliability

AI summary
Smart glasses include a frame and a temple, coupled to the frame. The temple includes a casing, a charging assembly, and a battery. The casing includes a tail end away from the frame. The tail end includes an end plate having a through hole. Both the charging assembly and the battery are disposed in the tail end. The charging assembly is coupled to the end plate. The charging assembly includes a charging contact disposed corresponding to the through hole. The battery is located on a side that is of the charging assembly and that is away from the end plate. A gap is formed between the charging assembly and the battery. The charging assembly is electrically coupled to an external charger.
