Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional smart glasses require frequent charging due to their compact nature and high-power requirements, making it inconvenient for users to charge them in public settings and ensuring continuous charging while in use.
Innovation Solution
A portable charging case with a glasses-retention portion and a retention bracket that securely holds smart glasses in place, ensuring stable charging through electrical contacts, and includes a battery to charge the smart glasses on the go.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If smart glasses are made compact to improve portability, then portability is improved, but battery life deteriorates requiring frequent charging
Solution Approach 1:
The patent implements a portable charging case that houses a rechargeable battery and charging contacts within a compact form factor. The smart glasses nest into this case for charging, with the case itself nesting portable charging capabilities. This nested structure allows the system to maintain portability while providing extended battery life through multiple charging cycles within the case.
2Extent of automation
If charging contacts are used to charge smart glasses, then charging capability is improved, but connection stability deteriorates when glasses are moved
Solution Approach 1:
The patent employs spring-loaded charging contacts that dynamically adjust to maintain stable electrical connection. The springs provide continuous contact pressure that compensates for movement or misalignment between the glasses and case, ensuring reliable charging connection even when the glasses are slightly moved within the case.
3Duration of action of moving object
If a portable charging case is used to extend battery life, then duration of action is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the charging case: it serves as a protective case for the smart glasses, a portable battery charger, and a display unit for charging status. By merging the charging case with the glasses case and integrating the battery and contacts directly into the case structure, the patent reduces overall system complexity compared to having separate charging devices.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The portable charging case allows for uninterrupted charging of smart glasses in any orientation, providing extended battery life by charging the glasses' battery at least once, and offering convenience for users in public settings.
Implementation Method 1
The glasses-retention portion may comprise a portion of the portable charging case that is configured to deflect, and upon deflection applies the resistance force to securely hold the smart glasses
Implementation Method 2
The glasses-retention portion may comprise a coil spring
Implementation Method 3
The glasses-retention portion may comprise a torsion spring
Implementation Method 4
The glasses-retention portion may comprise a leaf spring
Implementation Method 5
The leaf spring may comprise a magnet configured to adjust a bending force of the leaf spring
Implementation Method 6
The portable charging case may comprise a battery that is configured to charge another battery located within the smart glasses

AI summary
An example portable charging case for smart glasses comprises a glasses-retention portion of the charging case. The glasses-retention portion defines an interior surface of the portable charging case, and the glasses-retention portion is configured to apply a resistance force to securely hold smart glasses along the interior surface. The portable charging case also includes a retention bracket that is coupled with the glasses-retention portion. The retention bracket is configured to apply a force to the nose pad of the smart glasses to hold the smart glasses in place to facilitate stable charging between electrical contacts of the charging case and other electrical contacts on the nose pad of the smart glasses.
