Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rocker arm sleeves and supports are used to fix the steering mechanism, then the steering function is achieved, but the overall weight increases and mounting space is occupied
Solution Approach 1:
The patent removes the rocker arm sleeves and supports from the steering mechanism structure. The steering rocker arms are directly mounted on the frame without requiring separate support structures, thereby eliminating unnecessary components that increase weight while maintaining the essential steering function.
Solution Approach 2:
The frame structure is designed to directly bear and guide the steering rocker arms, combining the functions of support and steering mechanism into a unified structure. This multi-functional design eliminates the need for separate rocker arm supports, reducing overall weight while maintaining structural integrity and steering reliability.
2Reliability
If rocker arm sleeves and supports are used to fix the steering mechanism, then the steering function is achieved, but the mounting space increases
Solution Approach 1:
The patent eliminates the rocker arm sleeves and supports, removing the components that occupy mounting space. The steering mechanism is streamlined to use only essential components, thereby reducing the space required for mounting while maintaining steering functionality.
Solution Approach 2:
The support function previously provided by separate rocker arm supports is merged into the frame structure itself. The frame directly mounts and guides the steering rocker arms, combining structural support and steering mechanism functions into a single integrated structure, thereby reducing the total mounting space required.
3Reliability
If rocker arm sleeves and supports are used to fix the steering mechanism, then the steering function is achieved, but the assembly complexity increases
Solution Approach 1:
The patent removes the rocker arm sleeves and supports from the steering mechanism, eliminating components that complicate assembly. By reducing the number of parts, the assembly process becomes simpler and more straightforward while the essential steering function remains intact.
Solution Approach 2:
The patent integrates the support function into the frame structure, eliminating separate support components. This merging of functions reduces the number of parts that need to be assembled and connected, thereby simplifying the overall assembly process while maintaining the necessary steering functionality and structural support.
4Reliability
If rocker arm sleeves and supports are used to fix the steering mechanism, then the steering function is achieved, but the economic costs increase
Solution Approach 1:
The patent eliminates the rocker arm sleeves and supports, removing components that incur manufacturing costs. By reducing the bill of materials, the overall economic cost of manufacturing the steering mechanism is reduced while the essential steering function is preserved.
Solution Approach 2:
The patent combines the support function into the frame structure, eliminating the need for separate support components. This integration reduces the total number of parts that need to be manufactured, purchased, and assembled, thereby reducing economic costs while maintaining the necessary structural support and steering functionality.
Applied Scientific Principles
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 solution significantly reduces weight, compactness, and assembly complexity while lowering economic costs, enhancing reliability and providing space for additional systems.
Implementation Method 1
The elastic element is mainly used for mitigating impacts, which mainly depends on the elastic deformation of the elastic element and the tyre
Implementation Method 2
The function of the damping device is to absorb the energy of vertical vibration of the suspension and convert it into heat energy to be dissipated, so that the vibration can be rapidly attenuated
