Vehicle Interior Corner Assembly with Segmented Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner assemblies in vehicle interiors with right-angle joints pose hazards during sharp turns and are difficult to fabricate and maintain aesthetically, especially when using curved corner pieces that can be damaged during welding and installation.
Innovation Solution
A corner assembly design featuring an elongated main portion with lateral lip and flange sections forming receiving channels, paired with a cap section that can be securely snapped or attached over the main portion, allowing for easy assembly and maintenance of furniture pieces while maintaining an anodized finish and aesthetic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If curved corner pieces are used to join furniture panels, then safety is improved by eliminating right-angle hazards, but manufacturing complexity increases and aesthetic appearance deteriorates during welding and installation
Solution Approach 1:
The corner assembly is divided into three separate components: a corner piece with receiving channels, cap sections that cover the corner piece, and furniture panels. This segmentation allows each component to be manufactured independently using standard fabrication processes, eliminating the difficulty of creating complex curved joints while maintaining the safety benefits of rounded corners.
Solution Approach 2:
The corner piece acts as an intermediary component that receives and connects the furniture panels through its receiving channels. This intermediary structure provides the curved safety feature while allowing standard panel fabrication processes to remain unchanged, as panels simply attach to the pre-formed corner piece rather than being joined at right angles.
2Strength
If curved corner pieces are welded during furniture fabrication, then structural strength is improved, but the anodized finish deteriorates and requires re-painting
Solution Approach 1:
The cap sections are designed to be installed after the welding process is complete. This preliminary protection strategy ensures that the anodized finish on the corner piece is not exposed to welding heat and sparks, eliminating the need for re-painting or re-finishing while maintaining both structural strength and aesthetic appearance.
Solution Approach 2:
The cap section serves as a protective intermediary that covers the corner piece after welding. This allows the corner piece to be welded for structural strength while the cap section preserves the aesthetic anodized finish, effectively decoupling the structural and cosmetic functions.
3Object-affected harmful factors
If curved corner pieces are installed during furniture assembly, then safety and aesthetics are improved, but replacement becomes difficult once installed
Solution Approach 1:
The corner assembly is segmented into removable components with the corner piece featuring receiving channels that accept furniture panels. This segmentation allows the corner piece to be independently removed and replaced by detaching the panels from the receiving channels, making repair and replacement simple while maintaining the curved safety feature.
4Productivity
If standard welding processes are used to join furniture components, then productivity is improved, but the exterior surface and finish of components are degraded
Solution Approach 1:
The corner piece is pre-formed with the desired anodized finish using standard extrusion processes before assembly. This preliminary formation of the finished component allows welding to proceed efficiently without concern for finish degradation, as the cap section is installed afterward to protect the pre-established aesthetic quality.
Solution Approach 2:
The cap section acts as a protective intermediary that shields the pre-finished corner piece from welding damage. This allows standard welding processes to be used for joining furniture components with high productivity while the cap section preserves the exterior surface quality of the corner assembly.

AI summary
A corner assembly comprising an elongated main portion including a central section opposed by first and second lip sections, with the first and second lip sections extending laterally from the central section. The corner assembly additionally comprises first and second flange sections extending generally laterally from the central section, with the first flange section extending generally parallel with the first lip section and the second flange section extending generally parallel with the second lip section. The first flange section is separated from the first lip section so as to present a first receiving channel and the second flange section is separated from the second lip section so as to present a second receiving channel. The corner assembly further comprises an elongated cap section operable to be securely positioned over the elongated main portion.
