Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to place tools on the road surface, then the operator's accumulated experience can be utilized, but improper operation causes equipment damage
Solution Approach 1:
The patent replaces manual mechanical operation with an automated control system. The controller automatically controls the connecting rod driving unit and rotation driving unit to adjust the frame's orientation and position, eliminating the need for operator experience and manual placement decisions, thereby preventing equipment damage caused by improper operation
Solution Approach 2:
The patent implements a feedback control system where pressure sensors detect the pressure values between the frame and the ground, and the controller uses this feedback information to automatically adjust the connecting rod driving unit and rotation driving unit. This closed-loop control ensures accurate positioning without manual intervention and prevents equipment damage
2Strength
If high structural strength mechanical mechanism is used to mount heavy tools, then the suspension arm can support tools of 2 tons or more, but it is difficult to mount the suspension arm together with tools on middle size or smaller vehicles
Solution Approach 1:
The patent employs a dynamic adjustment mechanism consisting of the connecting rod driving unit and rotation driving unit that can automatically adapt the frame's orientation and position. This dynamic system allows the suspension arm to be adjusted to suitable angles and positions for mounting tools on various vehicle sizes, eliminating the need for high structural strength mechanisms while maintaining versatility
Solution Approach 2:
The patent changes the operational parameters of the suspension arm system by using the connecting rod driving unit to adjust the orientation and rotation driving unit to adjust the angle of the suspension arm. This parameter adjustment capability allows the same suspension arm to be adapted to different vehicle sizes and tool weights without requiring high structural strength mechanisms
3Ease of operation
If the frame is manually aligned with the ground, then the operator can determine placement by human eye, but the accumulated experience is relied upon causing improper placement
Solution Approach 1:
The patent replaces manual visual alignment with an automated control system. The controller automatically controls the connecting rod driving unit and rotation driving unit to adjust the frame's orientation based on pressure sensor feedback, eliminating reliance on operator experience and achieving precise placement accuracy
Solution Approach 2:
The patent implements a feedback control system where pressure sensors continuously monitor the pressure values between the frame and the ground. The controller uses this feedback information to automatically adjust the connecting rod driving unit and rotation driving unit, ensuring accurate placement without manual intervention and eliminating the variability introduced by operator experience
