Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for assembling vehicle sun visors require labor-intensive assembly and involve damage during removal, necessitating dedicated tools for disassembly.
Innovation Solution
A device featuring a clip with elastic fastening plates and a lever mechanism that allows easy installation and removal by rotating the lever and moving a clip fastening/removal bar, eliminating the need for dedicated tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fasten the pivot arm body to the vehicle body panel, then the mounting is secure and reliable, but assembly labor is required and assembly quality may deteriorate due to incomplete fastening
Solution Approach 1:
The clip structure performs self-service by automatically fastening to the vehicle body panel through elastic deformation of the elastic fastening plates. The locking jaws engage with the panel holes without requiring external tools or operators, achieving both reliability and ease of operation simultaneously.
Solution Approach 2:
The patent replaces the screw-based mechanical fastening system with an elastic clip-based system. The elastic fastening plates use elastic deformation rather than threaded mechanical engagement, eliminating the need for tools and operators while maintaining secure mounting.
2Ease of operation
If a clip is used to fasten the pivot arm body to the vehicle body panel, then assembly is simplified, but a separate dismantling operation is required and the pivot arm body is damaged due to forced removal
Solution Approach 1:
The clip structure incorporates dynamic elements that allow it to transition between fastening and removal states. The elastic fastening plates can deform to engage locking jaws during assembly, then deform again to release them during removal, enabling easy dismantling without damage.
Solution Approach 2:
The patent uses parameter changes in the elastic fastening plates - specifically changes in elastic deformation state - to control the fastening and removal processes. By changing the deformation parameter, the clip can easily transition from a secure locked state to a removable state without damaging the pivot arm body.
3Ease of operation
If a clip is used for fastening, then assembly is simplified, but dedicated tools are required for removal and maintenance
Solution Approach 1:
The lever serves multiple functions: it acts as a manipulation handle for the operator and simultaneously transmits force through the push body to the clip fastening/removal bar. This multi-functionality eliminates the need for separate dedicated tools while maintaining ease of operation.
Solution Approach 2:
The patent merges the manipulation handle and the force transmission mechanism into a single integrated lever structure. The lever combines the operator interface function with the mechanical advantage function, eliminating the need for separate tools and simplifying the overall system.

AI summary
Disclosed is a device for mounting interior parts of a vehicle. The device includes: a base plate for a sun visor pivot arm; a clip to mount the base plate on a vehicle body panel by a rotation of a lever and a forward movement of a clip fastening/removal bar. In particular, the clip can be automatically removed from the vehicle body panel by a reverse rotation of the lever and a backward movement of the clip fastening/removal bar, thereby allowing easy installation and removal of interior parts such as the sun visor.
