Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotational lever is rotatably connected with the equalizer lever in the power divider, then the front and rear brakes can work in an interlocked manner, but the structure inside the power divider becomes highly complicated and the number of components increases
Solution Approach 1:
The patent combines the functions of the equalizer lever and rotational lever into a single integrated lever structure. This unified lever directly connects the front and rear brake operating devices, eliminating the need for separate rotational connection components and simplifying the power divider structure while maintaining the interlocking brake function.
Solution Approach 2:
The integrated lever serves multiple functions simultaneously: it acts as both the equalizer lever for distributing braking force and the rotational lever for sequential brake activation. This multi-functional design reduces the total number of components needed in the power divider system.
2Reliability
If multiple components are used in the power divider to achieve interlocking brake operation, then the front and rear brakes can be actuated in sequence, but the size of the power divider increases
Solution Approach 1:
By merging the equalizer lever and rotational lever into one integrated component, the patent significantly reduces the volume occupied by the power divider. The sequential actuation function is achieved through the integrated lever's geometry and connection points rather than through multiple separate components.
Solution Approach 2:
The integrated lever is designed with specific connection points for front and rear brakes positioned at different locations along its length. This segmentation of connection points allows sequential brake actuation through the lever's rotation, eliminating the need for additional intermediate components and reducing overall power divider size.
