Vehicle Cabin Frame Trim Slit Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cabin structures struggle to securely fix interior articles at arbitrary positions, especially in vehicles with small wall surface areas, due to insufficient securing strength and limited application of groove-based attachment systems.
Innovation Solution
A vehicle cabin structure featuring a frame member with a frame trim that includes slits or grooves for attaching interior articles, utilizing positioning and attachment members that securely fasten to the frame trim via slits or grooves, allowing for rigid fixation of articles with large loads like handrails, even in vehicles with limited wall space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If grooves are provided in the wall surface for attaching interior articles, then interior articles can be fixed at arbitrary positions, but the securing strength may be too low to sufficiently fix interior articles
Solution Approach 1:
The frame trim is designed with locally reinforced portions at both ends of the slit, creating areas of higher strength precisely where attachment members need to be secured. This allows the trim to provide strong fixation points while maintaining overall flexibility for arbitrary positioning of interior articles.
Solution Approach 2:
The frame trim combines materials or structural elements with different properties - the main body provides flexibility and adaptability for various positions, while the reinforced portions provide the necessary strength for secure attachment. This composite approach resolves the contradiction between versatility and strength.
2Adaptability or versatility
If groove-based attachment systems are used, then interior articles can be attached, but the technology cannot be easily applied to vehicles having small wall surface areas
Solution Approach 1:
Instead of relying on wall surface area, the invention transitions to using the frame trim structure that extends vertically along the vehicle cabin. The slits are provided in the longitudinal direction of the frame trim, utilizing the vertical dimension and frame structure rather than horizontal wall surface area, thereby enabling attachment capability in vehicles with limited wall space.
3Shape
If the frame trim covers the frame member completely, then aesthetic appearance is improved, but attachment members cannot be securely fastened to the frame structure
Solution Approach 1:
The frame trim is segmented with slits that provide access for attachment members while maintaining overall coverage of the frame member. The trim is divided into sections - the reinforced portions that engage with attachments and the covered portions that provide aesthetic appearance. This segmentation allows both functions to coexist.
Solution Approach 2:
The slit acts as an intermediary element that allows attachment members to pass through and engage with the frame structure while the frame trim maintains its covering function. The reinforced portions serve as intermediaries that transfer and distribute the attachment loads to the frame structure, enabling secure fastening without compromising the covering aesthetic.

AI summary
A vehicle cabin structure includes a pillar constituting a framework of a vehicle cabin, and a pillar trim which is an interior member arranged with a clearance from a vehicle cabin inside facing surface of the pillar and covering the vehicle cabin inside facing surface of the pillar. The pillar trim has, in its surface facing toward inside of the vehicle cabin, a slit extending along the pillar.
