Reversible Strap Clips for Goggle Fit and Electrical Conduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goggles with strap attaching arrangements fail to provide an effective fit when worn with or without a helmet, and they do not adequately accommodate electrical or signal systems.
Innovation Solution
The design incorporates reversible snap-connected clip portions that can adjust orientation to accommodate both helmet and no-helmet configurations, ensuring a precise fit and effective electrical or signal conduction to the goggle frame or lens, using a strap with adjustable length and electrical conductors for power and signal delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If clip portions are extended outwardly to accommodate helmet width, then goggles can be worn with a helmet, but the strap does not conform to the user's head shape when worn without a helmet
Solution Approach 1:
The clip portions are made pivotable relative to the goggle frame, allowing them to dynamically change orientation between extended (for helmet wear) and retracted (for direct head wear) positions, thus adapting to different wearing conditions
2Adaptability or versatility
If clip portions are hinged to pivot for helmet accommodation, then versatility is improved, but structural reliability may be reduced
Solution Approach 1:
The clip portions incorporate a pivot mechanism that allows controlled rotation between orientations while maintaining secure attachment to the frame through snap-connecting elements, providing both flexibility and structural integrity
3Device complexity
If conventional strap attaching arrangements are used, then simplicity is maintained, but effective fit with electrical systems is not achieved
Solution Approach 1:
The clip portions integrate both mechanical attachment functions (strap securing) and electrical conduction functions (signal/power transmission) into a single component structure, eliminating the need for separate attachment and wiring systems

AI summary
Goggles include a strap, a frame, at least one lens, and first and second connectors. The strap has opposite strap free ends. The frame has a lateral center and opposite lateral end portions. Each connector has a base portion for connecting to the opposite lateral end portion of the frame, and a strap-mounting portion for connecting to the opposite strap free end of the strap. Each strap-mounting portion has a strap connecting end where the strap meets the strap-mounting portion. Each of the first and second connectors have a first orientation for helmet-less usage and a second orientation for helmet usage. The strap connecting end of each connector is located a greater distance from the lateral center of the frame when the connector is in a second orientation than when in the first orientation.
