Eccentric Clip Mounting Structure for Stable Panel Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting structures struggle to maintain adjusted relative positions between members due to the difficulty in preventing the pulling-out of rotatable and slidable shafts, making it hard to maintain the adjusted positions.
Innovation Solution
A mounting structure utilizing a clip with a first shaft portion and a second shaft portion, where the axial center of the second shaft is eccentric to the first shaft, and a polygonal cross-sectional shape of the first shaft portion that restricts rotation by abutting the hole wall, ensuring the adjusted positions are maintained through the use of anchor and flange portions for stable nipping pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the second shaft portion is engaged with the second mounting hole so as to be rotatable and slidable, then mounting flexibility is improved, but the ability to maintain adjusted relative positions deteriorates
Solution Approach 1:
The shaft portions are designed to be movable (rotatable and slidable) during the mounting process to enable adjustment of relative positions, but become fixed after adjustment is complete, transitioning from dynamic to static state to maintain the adjusted position
Solution Approach 2:
The clip is divided into multiple functional segments: shaft portions for insertion and movement, anchor portions for securing, and positioning portions for maintaining relative positions. This segmentation allows different parts to perform different functions - movement during adjustment and fixation after adjustment
2Adaptability or versatility
If the axial center of the second shaft portion is eccentric with respect to the axial center of the first shaft portion, then mounting adaptability is improved, but position stability deteriorates
Solution Approach 1:
The clip employs asymmetric design with eccentric axial centers of the two shaft portions, allowing the mounting structure to accommodate misaligned mounting holes while the anchor and positioning portions ensure stable maintenance of the adjusted relative position
3Stability of the object's composition
If the cross-sectional shape of the first shaft portion is a polygonal shape with length longer than the minimum opening length of the first through-hole, then rotation restriction is improved, but insertion difficulty increases
Solution Approach 1:
The first shaft portion has different cross-sectional characteristics at different locations: a polygonal cross-section at the positioning portion for rotation restriction, and a smaller cross-section at the insertion end to facilitate easy insertion through the through-hole

AI summary
A mounting structure has: a first member in which a first through-hole is formed; a second member in which a second through-hole is formed; and a clip having a first shaft portion, a first anchor portion that is anchored on an edge portion of the first through-hole, a second shaft portion whose axial center is eccentric with respect to an axial center of the first shaft portion, and a second anchor portion that is anchored on an edge portion of the second through-hole, wherein a cross-sectional shape of a portion, which is disposed at an inner side of the first-through hole, of the first shaft portion is a polygonal shape, and a length along a longest diagonal line of the polygonal shape, or a length of a longest side of the polygonal shape, is longer than a minimum opening length of the first through-hole.
