Fastening Clip with Guiding Bars for Axial Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening clips for connecting components of different thicknesses are complex and prone to tilting, making it difficult to align the receptacle and fastening opening, which complicates the screwing process and limits adaptability to varying component thicknesses.
Innovation Solution
The clip features guiding bars that connect the pin receptacle to the holder, allowing elastic axial movement without tilting, ensuring the receptacle remains aligned with the leg's opening, and can be axially displaced to accommodate different thicknesses, using a parallelogram linkage for reliable guidance and a securing section to prevent rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If axially resilient fastening is used to adapt to different component thicknesses, then adaptability to varying thicknesses is improved, but device complexity increases and tilting occurs causing misalignment
Solution Approach 1:
The pin receptacle is designed to move dynamically in the axial direction relative to the leg through guiding bars, allowing the receiving slit to adapt to different component thicknesses. The guiding bars enable controlled axial movement while preventing tilting, maintaining alignment between the receptacle opening and fastening opening throughout the movement range.
2Adaptability or versatility
If axially resilient fastening is used to adapt to different component thicknesses, then adaptability to varying thicknesses is improved, but device complexity increases
Solution Approach 1:
The pin receptacle is designed to move dynamically in the axial direction relative to the leg through guiding bars, allowing the receiving slit to adapt to different component thicknesses. The guiding bars enable controlled axial movement while preventing tilting, maintaining alignment between the receptacle opening and fastening opening throughout the movement range.
3Adaptability or versatility
If flexible clasp configurations are used for axial movement, then adaptability to different thicknesses is improved, but alignment reliability deteriorates due to tilting
Solution Approach 1:
The pin receptacle moves axially relative to the leg through guiding bars that constrain movement to purely axial translation. This dynamic design allows adaptation to different thicknesses while the guiding bars prevent rotational movement, ensuring the receptacle opening remains aligned with the fastening opening throughout the adjustment range.
Solution Approach 2:
The guiding bars act as intermediary elements between the pin receptacle and the leg, mediating the axial movement while preventing tilting. These guiding bars transmit the axial displacement force and maintain the geometric relationship between the receptacle and leg, ensuring reliable alignment during thickness adaptation.
