Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior cladding arrangements for vehicle load spaces reduce available load volume and increase installation complexity and costs due to the need for multiple mounting steps and space-consuming components.
Innovation Solution
An interior cladding arrangement featuring a support wall with a support wall connecting portion and a cover wall with a cover wall connecting portion, where the connecting elements are configured for mutual guided engagement, allowing for a precise and easy installation without additional mounting steps like welding or clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If support walls and cover elements are installed separately using screw fittings or clamps, then installation flexibility is improved, but device complexity and space requirements increase
Solution Approach 1:
The support wall and cover element are merged into a single integrated component during the molding process. The support wall includes integrated connecting elements (such as hooks, lugs, or recesses) that directly engage with corresponding elements on the cover element, eliminating the need for separate fixing devices like screw fittings or clamps. This integration reduces device complexity while maintaining installation flexibility.
Solution Approach 2:
The fixing function is extracted from separate fixing devices and integrated directly into the support wall structure. The support wall includes built-in connecting elements that perform the fixation function, removing the need for additional external fixing components and simplifying the overall assembly.
2Ease of operation
If interior cladding components are arranged spaced apart from the body shell, then ease of installation is improved, but load space volume is reduced
Solution Approach 1:
The support wall and cover element are merged into a single integrated component that can be installed as one piece directly against the body shell. This integration eliminates the need for spacing between components, maximizing load space volume while maintaining ease of installation through the integrated connecting elements.
Solution Approach 2:
The connecting elements are nested within the structure of the support wall and cover element themselves, rather than requiring external fixing devices. This allows the components to be positioned closely together against the body shell, maximizing the available load space while maintaining installation simplicity.
3Strength
If cover elements are welded together before installation, then structural strength is improved, but manufacturing complexity increases
Solution Approach 1:
The support wall and cover element are merged into a single integrated component molded as one piece. The connecting elements are formed as integral parts of the molded structure, eliminating the need for separate welding operations while maintaining structural strength through the monolithic construction.
Solution Approach 2:
The manufacturing process is changed from assembly-based (requiring welding) to molding-based. The connecting elements are formed during the injection molding process with appropriate geometric parameters (hooks, lugs, recesses) that provide structural strength without requiring post-molding welding operations.
4Reliability
If multiple mounting steps and devices are used, then installation reliability is improved, but productivity is reduced
Solution Approach 1:
Multiple mounting steps are merged into a single installation operation. The integrated support wall and cover element with built-in connecting elements can be installed in one step by directly engaging the connecting elements, eliminating the need for multiple separate mounting operations while maintaining installation reliability through the robust integrated connection.
Solution Approach 2:
The connecting elements are pre-formed as integral parts of the molded support wall and cover element during manufacturing. This preliminary formation of connection features eliminates the need for time-consuming on-site assembly steps, allowing for rapid installation while ensuring reliable connection through the pre-engineered geometric features.
