Sun Visor Holder Groove Structure for Easy Clip Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sun visor holder design faces difficulties in easy removal from a mounting hole due to the second engaging piece's limited flexibility, which can lead to it being stuck in the hole.
Innovation Solution
The sun visor holder incorporates a leg portion with a first engaging piece that can be flexed and deformed by a slit, and a pair of second engaging pieces that can be easily flexed and deformed due to groove portions on the second wall portion, allowing for easy release from the mounting hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second engaging piece is made rigid to ensure stable engagement with the mounting hole, then the engagement reliability is improved, but the ease of removal deteriorates because the piece cannot be easily flexed for disengagement
Solution Approach 1:
The leg portion is divided into multiple wall portions (first, second, third wall portions) with distinct functions. The second wall portion contains the second engaging piece for stable engagement, while the third wall portion provides the groove for enabling flexing during removal. This segmentation allows different parts to optimize for their specific functions without compromise.
Solution Approach 2:
The groove is provided locally in the third wall portion rather than throughout the entire structure. This localized flexibility feature allows the second engaging piece to flex only where needed for removal while maintaining rigidity in other areas for stable engagement during normal use.
2Ease of operation
If the second engaging piece is made flexible to enable easy removal from the mounting hole, then the ease of operation is improved, but the engagement stability deteriorates because the piece may deform during normal use

The leg portion is divided into multiple wall portions with distinct functions. The second wall portion contains the second engaging piece for stable engagement, while the third wall portion provides the groove for enabling flexing during removal.

Solution Approach 2:
The groove is provided locally in the third wall portion rather than throughout the entire structure. This localized flexibility feature allows the second engaging piece to flex only where needed for removal while maintaining rigidity in other areas for stable engagement during normal use.
3Ease of manufacture
If the leg portion is designed with simple structure for easy manufacture, then the manufacturing cost is reduced, but the ease of removal deteriorates because there are no features to facilitate flexing of the engaging pieces
Solution Approach 1:
The groove is provided locally in the third wall portion rather than throughout the entire structure. This localized flexibility feature allows the second engaging piece to flex only where needed for removal while maintaining rigidity in other areas for stable engagement during normal use.
Solution Approach 2:
The groove creates a thin-walled structure in the third wall portion that is intentionally designed to be flexible. This allows the engaging piece to deform elastically during removal operations while maintaining structural integrity for its primary engagement function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables the sun visor holder to be easily removed from the mounting hole by facilitating the flexural deformation of the second engaging pieces, ensuring smooth detachment and improved attachment security.
Implementation Method 1
a first engaging piece that is configured to be flexed and deformed by a slit and engages with the mounting hole
Implementation Method 2
a pair of second engaging pieces that are configured to be flexed and deformed and are engaged with the mounting hole

AI summary
A sun visor holder includes a base portion and leg portion. The leg portion includes a first wall portion and a second wall portion that are vertically disposed from the base portion and face each other. The first wall portion includes a first engaging piece provided with a release portion. The second wall portion includes a pair of second engaging pieces whose base end portions are connected to a tip end side of the second wall portion, and a vertical wall that is disposed between the pair of second engaging pieces and extends in a vertical direction of the second wall portion. Groove portions that extend in the vertical direction of the second wall portion and thin the second wall portion are formed on the second wall portion between each of the second engaging pieces and the vertical wall.
