Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stabilizer pads for work machines, made from solid rubber, are expensive and prone to damage, requiring frequent replacement, while masticated rubber pads, though cost-effective and durable, are not easily manufactured into horizontal surfaces for ground contact.
Innovation Solution
A stabilizer pad design featuring a frame with a resilient member comprising multiple fiber-reinforced elastomeric pads and a fabric layer, providing a continuous horizontal ground contact surface, which is easy to manufacture and durable, with elastomeric coatings for enhanced wear resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid rubber is used for the stabilizer pad, then wear resistance and durability are improved, but manufacturing cost increases and the pad becomes more prone to chunking and breaking
Solution Approach 1:
The stabilizer pad uses a composite structure combining a rigid support means with a resilient pad made of masticated rubber (fiber-reinforced elastomeric material). This composite approach allows the pad to achieve the durability of solid rubber while being more cost-effective to manufacture, as masticated rubber is less expensive than solid rubber and resistant to chunking and breaking.
2Ease of manufacture
If masticated rubber is used for the stabilizer pad, then manufacturing cost decreases and wear properties improve, but the pad cannot maintain a horizontal ground contacting surface
Solution Approach 1:
The resilient pad is segmented into multiple layers of masticated rubber sheets stacked together. This segmentation allows each layer to be manufactured separately as flat sheets and then assembled into a composite pad structure that maintains a horizontal ground contacting surface while using cost-effective masticated rubber material.
Solution Approach 2:
The combination of multiple masticated rubber layers with a rigid support means creates a composite structure that solves the shape problem. The rigid support provides structural integrity to maintain horizontality, while the layered masticated rubber provides the cost-effective, durable contact surface.
3Reliability
If multiple masticated rubber sheets are stacked to create the resilient pad, then durability and grip are improved, but the manufacturing process becomes more complex
Solution Approach 1:
The resilient pad is divided into multiple discrete masticated rubber sheets that can be manufactured independently using standard sheet production processes. This segmentation simplifies the overall manufacturing process compared to creating a single large pad, as each sheet can be produced separately and then assembled through stacking and bonding.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances grip and wear resistance, reduces the frequency of pad replacement, and maintains a stable working foundation for work machines by distributing forces effectively across the ground contact surface.
Implementation Method 1

Implementation Method 2
it is known to coat at least the ground contacting surface with a relatively soft, pliable material, such as rubber, to prevent damage to the surface
