Dual-Hardness Chassis Anti-Slip Pad for Stable Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-slip mats for chassis are either too soft to be firmly fixed or too hard to provide shock absorption, failing to offer a balance between stability and shock absorption.
Innovation Solution
A two-shot injection molded anti-slip pad with a soft PC support member and a hard TPE insert member, where the insert member is fixed to the support member using a reinforcement rib and bonding groove, providing increased adhesion and stability while allowing for shock absorption and a flush, dustproof mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the anti-slip mat is made too soft, then shock absorption is improved, but fixation stability deteriorates
Solution Approach 1:
The anti-slip mat is divided into two distinct segments: a soft support member (first material) for shock absorption and a hard insert member (second material) for fixation stability. This segmentation allows each part to perform its specific function optimally without compromising the other.
Solution Approach 2:
The invention uses composite materials consisting of two different materials with different hardness properties. The first material (softer) provides shock absorption while the second material (harder) provides fixation stability, resolving the contradiction between softness and stability.
2Stability of the object's composition
If the anti-slip mat is made too hard, then fixation stability is improved, but shock absorption deteriorates
Solution Approach 1:
The anti-slip mat is divided into two distinct segments: a soft support member (first material) for shock absorption and a hard insert member (second material) for fixation stability. This segmentation allows each part to perform its specific function optimally without compromising the other.
Solution Approach 2:
The invention uses composite materials consisting of two different materials with different hardness properties. The first material (softer) provides shock absorption while the second material (harder) provides fixation stability, resolving the contradiction between softness and stability.
3Ease of manufacture
If a single-material anti-slip mat is used, then manufacturing simplicity is maintained, but performance balance between fixation and shock absorption deteriorates
Solution Approach 1:
The invention uses composite materials consisting of two different materials with different hardness properties. The first material (softer) provides shock absorption while the second material (harder) provides fixation stability, resolving the contradiction between softness and stability.
Solution Approach 2:
The invention changes the material parameter (hardness) by using two different materials with different hardness values. The softer first material provides shock absorption while the harder second material provides fixation stability, achieving optimal performance balance.

AI summary
A chassis includes a housing and at least one anti-slip pad mounted on the housing. The housing includes a mounting slot. The anti-slip pad includes a support member and an insert member coupled to the support member. The support member is configured to support the housing. The insert member is configured to latch in the mounting slot. A hardness of the insert member is greater than a hardness of the support member.
