Eyeglasses Charging Case With Auto-Locking Contact Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems for electronic eyeglasses require manual alignment and retention at the nosepiece to ensure stable contact for charging, leading to potential disconnection during movement or impact.
Innovation Solution
A case with rocking retention means featuring magnets and pins that automatically engage with the eyeglasses' hinge area upon insertion, ensuring secure charging without manual alignment or nosepiece retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional charging systems use pins and magnets at one end of the case, then charging contact can be established, but the eyeglasses require manual positioning and retention devices to prevent movement
Solution Approach 1:
The retention means are designed to move from an inactive position to an active position automatically when the eyeglasses are inserted. This dynamic mechanism engages the charging contacts and secures the eyeglasses without requiring manual positioning, resolving the contradiction between reliable charging contact and ease of operation
Solution Approach 2:
The system performs self-positioning and self-retention through the automatic engagement of retention means. When the eyeglasses are placed in the case, the retention means automatically move to engage the charging area and lock the eyeglasses in place, eliminating the need for user intervention and ensuring stable charging contact
2Reliability
If retention devices are added at the nosepiece to prevent movement, then charging stability improves, but device complexity and cost increase
Solution Approach 1:
The invention removes the need for retention devices at the nosepiece by extracting the retention function and relocating it to the case structure. The retention means are integrated into the case body, eliminating additional components on the eyeglasses themselves and reducing overall device complexity while maintaining charging stability
Solution Approach 2:
The retention function is merged with the charging mechanism in the case. The same retention means that secure the eyeglasses also establish charging contact, combining two functions into a single integrated system rather than requiring separate retention devices and charging components
3Ease of operation
If the eyeglasses are simply placed in the case, then ease of operation improves, but the eyeglasses may move around and lose contact with charging pins
Solution Approach 1:
The retention means dynamically respond to the insertion of the eyeglasses by moving from an inactive to an active position. This automatic engagement maintains charging contact reliability while requiring only simple placement by the user, resolving the contradiction between ease of operation and charging contact maintenance
Solution Approach 2:
The system provides mechanical feedback through the engagement of retention means that automatically detect and respond to the presence of the eyeglasses. This feedback mechanism ensures the eyeglasses are properly positioned and secured for charging without requiring user intervention, maintaining both ease of operation and charging reliability
