Rotating Mounting Structure for Elastic Engagement Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting structures for components with elastic engagement arms are poorly operable during removal, leading to potential breakage of the arms, especially when withdrawn from their mounting portions.
Innovation Solution
A mounting structure featuring first, second, and third shape portions that allow components to be inserted and rotated, engaging with the arms only when positioned vertically, preventing removal through other directions and releasing engagement when reversed, thus enhancing operability and preventing arm breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the first coupler is removed by deforming the engagement arms against their elastic force, then the coupler can be detached from the mounting portion, but the operability is poor and the engagement arms might break
Solution Approach 1:
The mounting structure transitions from a static engagement hole to a dynamic multi-stage engagement process. The component is inserted through a passage, rotated to a predetermined angle for engagement arms to engage with third shape portions, and can be removed by reverse rotation. This dynamic process eliminates the need to deform engagement arms against elastic force, improving both operability and reliability.
Solution Approach 2:
The mounting structure adds a rotational dimension to the engagement process. Instead of linear insertion and extraction, the component is inserted through a passage and then rotated within a space defined by second shape portions. This dimensional change enables engagement arms to engage with third shape portions at a predetermined angle, allowing easy removal by reverse rotation without deforming the arms.
2Stability of the object's composition
If the engagement arms are made elastic to enable engagement, then the component can be securely mounted, but the arms are vulnerable to breakage during removal operations
Solution Approach 1:
The removal process is made dynamic through reverse rotation. The component is removed by rotating in the opposite direction to the engagement rotation, which naturally releases the engagement arms from the third shape portions. This dynamic removal process maintains engagement stability during mounting while making removal easy without risking arm breakage.
Solution Approach 2:
The removal operation is performed by inverting the engagement process. Instead of pulling or forcing the component out, the component is rotated in the reverse direction of engagement. This inversion causes the engagement arms to naturally disengage from the third shape portions, maintaining their elastic integrity while enabling easy removal.
3Ease of operation
If the component is allowed to rotate within the mounting structure, then the engagement arms can engage with the third shape portions, but the component must be precisely positioned
Solution Approach 1:
The first shape portions are asymmetrically configured to define a passage that only allows insertion when engagement arms are in the correct vertical position. This asymmetric design guides the component into the proper orientation during insertion, eliminating the need for high positioning precision while enabling smooth rotation and engagement with the third shape portions.

AI summary
The mounting structure includes a pair of first shape portions, a pair of second shape portions, and a pair of third shape portions. The pair of first shape portions are opposed to each other to define therebetween a passage which allows the component to be inserted into and withdrawn from the mounting structure therethrough. The pair of second shape portions are opposed to each other to define therebetween a space which allows the component inserted through the passage between the pair of first shape portions to rotate therein. The pair of third shape portions come into engagement with the engagement arms when the component positioned between the pair of second shape portions is rotated through a predetermined angle. The pair of third shape portions are opposed to each other and incorporated in the pair of second shape portions.
