Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for rear spoilers on motor vehicles often experience play and misalignment due to manufacturing tolerances and varying installation conditions, leading to suboptimal support and potential instability.
Innovation Solution
A mounting holder with an elastic, S-shaped holding portion that connects to the lower part of the rear spoiler and a fastening portion for securing to a body component, designed to prevent play and enhance support by compensating for manufacturing tolerances through adjustable geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid mounting system is used to ensure stable connection, then connection strength is improved, but manufacturing tolerances and installation variations cause play and misalignment
Solution Approach 1:
The holding portion is designed with elastic properties, allowing it to flex and adapt to manufacturing tolerances and installation variations. This dynamic characteristic enables the rigid fastening portion to maintain strong connection while the elastic holding portion compensates for dimensional variations, eliminating play and misalignment.
Solution Approach 2:
The elastic holding portion changes its physical state from rigid to flexible, allowing it to deform within elastic limits to accommodate tolerance variations. This parameter change enables the system to maintain both connection strength and alignment precision by adjusting the flexibility parameter of the holding portion.
2Manufacturing precision
If an elastic holding portion is used to compensate for manufacturing tolerances, then alignment precision is improved, but connection rigidity may be reduced
Solution Approach 1:
The mounting holder is divided into two distinct functional segments: a rigid fastening portion for strong connection and an elastic holding portion for precision alignment. This segmentation allows each part to optimize its properties independently - the fastening portion provides rigidity while the holding portion provides elasticity for tolerance compensation.
Solution Approach 2:
Different parts of the mounting holder have different mechanical properties - the fastening portion is rigid for strong attachment while the holding portion is elastic for tolerance compensation. This local quality differentiation allows the system to simultaneously achieve both connection strength and alignment precision in different locations.
3Force
If a rigid connection is used to provide stable support, then force distribution is improved, but play occurs due to tolerance accumulation
Solution Approach 1:
The elastic holding portion introduces dynamic adaptability to the connection system, allowing it to self-adjust to tolerance variations while maintaining stable force distribution. The elastic deformation absorbs dimensional variations, ensuring that forces are distributed evenly without creating play or instability in the overall connection.
