Dual Elastic Clip for Sun Visor Clamping Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hands-free electronic devices with elastic clips struggle to provide sufficient clamping force on thin sun visors, leading to device separation and potential damage to the display cover plate, and result in an unsightly gap between the clip and the housing.
Innovation Solution
The hands-free electronic device incorporates a dual elastic element system with a curved structure and additional clamping features, including a second elastic element with a concave surface and enhancement ribs, to enhance clamping ability and distribute stress effectively, allowing secure attachment to sun visors of varying thicknesses without damaging the cover plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a conventional elastic clip is used to clamp thin sun visors, then the device can be attached to sun visors, but the elastic clip cannot provide sufficient clamping force and the device easily becomes separated
Solution Approach 1:
The elastic clip is divided into two separate elastic elements (first and second elastic elements) that work together. The first elastic element provides initial clamping force while the second elastic element provides additional clamping force, together achieving sufficient holding force for both thin and thick sun visors without compromising attachment stability.
Solution Approach 2:
The second elastic element is disposed within the holding space defined by the first elastic element's curved structure. This nested arrangement allows both elastic elements to cooperate efficiently, with the second element providing supplemental clamping force while being contained within the structural framework of the first element.
2Adaptability or versatility
If the elastic clip clamps to thin sun visors, then the device can be attached, but a gap is formed between the elastic clip and the housing and the appearance suffers
Solution Approach 1:
The elastic elements are designed to be flexible and adaptable to different sun visor thicknesses. The curved structure with concave surfaces allows the elastic elements to dynamically adjust their configuration, maintaining full contact with the housing across various thickness conditions and preventing gap formation that would compromise appearance.
3Force
If the conventional display cover plate bears increased torque, then the clamping force is sufficient for thick sun visors, but the cover plate easily becomes damaged
Solution Approach 1:
The clamping function is segmented between two elastic elements rather than relying on the display cover plate to provide all clamping force. This distribution of mechanical stress protects the cover plate from excessive torque while maintaining sufficient clamping capability through the coordinated action of both elastic elements.
Solution Approach 2:
The two elastic elements act as intermediary components that provide the clamping force, reducing the direct mechanical stress and torque transmitted to the display cover plate. This intermediary mechanism protects the cover plate from damage while achieving the required clamping force for secure attachment.
