Deformable Abutment Spacer for Vehicle Bodywork Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temporary spacer devices for motor vehicle bodywork components, such as doors and tailgates, are prone to damage due to poor resistance against the forces and stresses exerted during installation and transport, leading to shocks and potential deformation or rupture.
Innovation Solution
A temporary spacer device with a deformable abutment capable of elastic deformation along a longitudinal axis, featuring a rounded head and throttle zone for improved force distribution, and an elastic retaining lug for secure locking, fabricated from thermoplastic material to withstand high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid abutment is used in the temporary spacer device, then the mechanical solidity and structural strength are improved, but the device becomes vulnerable to damage from shocks and forces during installation and transport
Solution Approach 1:
The abutment's rigidity parameter is changed by introducing an elastic deformable part that can dynamically adjust its stiffness. This part is designed to deform elastically under shock loads while maintaining structural integrity, transforming the abutment from a purely rigid structure to one with controlled flexibility that absorbs impact energy
Solution Approach 2:
The abutment is constructed as a composite structure combining a rigid base for structural support with an elastic deformable part for shock absorption. This composite design integrates materials with different mechanical properties to simultaneously achieve both strength and impact resistance
2Strength
If the abutment is designed to be highly resistant to forces, then the protection against deformation is improved, but the device complexity increases
Solution Approach 1:
The abutment is segmented into distinct functional zones: a rigid base portion for structural support and anchoring, and an elastic deformable part for shock absorption. This segmentation allows each part to be optimized for its specific function while simplifying the overall design compared to a uniformly complex structure
Solution Approach 2:
Different parts of the abutment are assigned different mechanical properties locally - the base is made rigid for strength, while the deformable part is made elastic for shock absorption. This local differentiation of material properties achieves force resistance without requiring the entire structure to be complex
