Vehicular Door Trim Assembly With Integrated Mount Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular door trims face challenges in achieving a simple mounting process, ensuring strong mounting, and optimizing space utilization for components such as the armrest, pull handle, and switch base.
Innovation Solution
A vehicular door trim design featuring mount members that facilitate easy assembly by fitting together, including a first mount member on the armrest, a second mount member on the pull handle, and a third mount member on the switch base, which collectively reduce the need for multiple operations and save space while enhancing mounting strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate members (pull handle piece, door center piece) are used with multiple fitting pieces and clips, then the door trim components can be securely fixed to the door trim body, but the mounting process becomes complex and requires more mounting spaces
Solution Approach 1:
The patent combines the pull handle piece and door center piece into a single integrated door trim component. The integrated design eliminates the need for separate fitting pieces and multiple clips, reducing mounting complexity while maintaining structural integrity through a unified construction that secures both functional elements simultaneously
2Reliability
If multiple separate components are mounted individually with multiple fitting pieces, then each component can be securely attached, but the mounting space required increases
Solution Approach 1:
By merging the pull handle and door center into one integrated component, the patent reduces the total mounting space required. The unified structure allows both elements to be secured through a single mounting location rather than requiring separate mounting spaces for multiple independent components, thereby maintaining reliability while conserving space
3Stability of the object's composition
If separate members with multiple clips and fitting pieces are used, then the components can be fixed to the door trim, but the number of parts and assembly steps increases
Solution Approach 1:
The integrated door trim design merges multiple separate members into a single component, directly reducing the number of parts that need to be assembled. This eliminates multiple assembly steps involving separate clips and fitting pieces, thereby improving assembly efficiency and productivity while the unified construction inherently maintains compositional stability

AI summary
A vehicular door trim includes an armrest including a first mount member, a pull handle, an opening section, and a switch base. The pull handle includes a body portion and an extending portion that extends from the body portion and includes a second mount member that is fitted to the first mount member. The opening section is defined by the armrest and the extending portion with the second mount member being fitted to the first mount member. The switch base includes a third mount member that is fitted to the second mount member and disposed in the opening section to cover the opening section with the third mount member being fitted to the second mount member.
