Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional metal wheel rims (iron or aluminum alloy) are used, then strength and durability are improved, but vehicle weight increases leading to higher fuel or electrical power consumption
Solution Approach 1:
The patent applies composite materials by combining plastic resin with reinforcing fibers (glass, carbon, or aramid) to create a wheel rim that is both lightweight and strong. The composite structure provides high strength-to-weight ratio, resolving the contradiction between strength and weight by using a material system that inherently combines both properties rather than relying on metal alone.
Solution Approach 2:
The patent changes the material parameters by transitioning from metallic materials to plastic composite materials with specific fiber reinforcements. This parameter change enables the wheel rim to achieve comparable strength to metal while significantly reducing weight, thereby resolving the technical contradiction between strength and weight.
2Weight of moving object
If aluminum alloy wheel rims are used instead of iron, then weight is reduced and deformability is improved, but manufacturing cost increases
Solution Approach 1:
The patent changes the material composition parameters by using plastic resin combined with reinforcing fibers instead of aluminum alloy. This parameter change enables cost-effective manufacturing while achieving lightweight properties, as plastic composites can be manufactured through conventional molding processes at lower cost than aluminum alloy wheel rims.
Solution Approach 2:
The patent employs cost-effective plastic composite materials that can be manufactured more cheaply than aluminum alloy, making the wheel rim an economical alternative that achieves lightweight performance without the high manufacturing costs associated with aluminum alloy processing.
3Use of energy by moving object
If vehicle weight is reduced to decrease fuel or electrical power consumption, then energy efficiency is improved, but structural strength and durability may be compromised
Solution Approach 1:
The patent uses composite materials with reinforcing fibers embedded in plastic resin to maintain structural strength while reducing weight. The fiber reinforcement provides the necessary structural integrity and durability, ensuring that energy efficiency improvements do not come at the cost of compromised reliability.
Solution Approach 2:
The patent changes the material parameters to achieve optimal strength-to-weight ratio, enabling the wheel rim to be lightweight enough to improve energy efficiency while maintaining sufficient structural strength and durability through the composite material formulation.
