Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heavy materials are distributed using traditional machinery, then distribution efficiency is improved, but ground surface damage increases
Solution Approach 1:
The patent changes the physical parameters of the vehicle by replacing traditional steel wheels with rubber tracks, which fundamentally alters the pressure distribution characteristics. This parameter change allows the vehicle to maintain high productivity while reducing ground surface damage through lower contact pressure and larger contact area.
Solution Approach 2:
The patent uses composite material construction by combining rubber tracks with the vehicle frame, creating a hybrid system that leverages the load-bearing capacity of the frame while utilizing the ground-protection properties of rubber tracks. This composite approach resolves the contradiction between structural strength and ground protection.
2Force
If machinery is used to distribute heavy materials, then distribution capability is improved, but environmental sensitivity impact worsens
Solution Approach 1:
The patent modifies the operational parameters by using rubber tracks to reduce ground pressure and noise levels, enabling the machinery to handle heavy materials while minimizing environmental impact. The parameter changes in contact pressure and noise emission directly address the environmental sensitivity concern.
3Ease of operation
If conventional vehicles are used indoors, then material transport is enabled, but concrete flooring damage occurs
Solution Approach 1:
The patent changes the contact parameters by using rubber tracks instead of steel wheels, which significantly reduces the pressure applied to concrete floors. This parameter change enables indoor material transport operations while protecting the concrete flooring from damage.
4Force
If steel tracks are used for propulsion, then traction is improved, but noise pollution and vibration increase
Solution Approach 1:
The patent applies composite material principles by using rubber tracks that combine the traction capabilities needed for heavy material transport with the noise and vibration reduction properties of rubber. This material substitution resolves the contradiction between traction performance and harmful emissions.
Solution Approach 2:
The patent changes the material parameters of the tracks from steel to rubber, which fundamentally alters the noise and vibration characteristics while maintaining adequate traction. This parameter change directly addresses the noise pollution and vibration issues.
