Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power supply cable is positioned in the front part of the bearing frame, then the machine can be powered, but the front part cannot accommodate work equipment
Solution Approach 1:
The power supply cable is extracted from the front part of the bearing frame and routed through the rear part, allowing the front part to be freely used for work equipment while the cable passes through dedicated guides and storage compartments in the rear section
Solution Approach 2:
A distribution arm is introduced as an intermediary component that manages the cable routing between the rear storage compartment and the front connection point, preventing cable interference with work equipment while maintaining power supply functionality
2Area of stationary object
If the cable length is increased to expand workable area, then the machine can cover larger areas, but cable interference and entanglement increase
Solution Approach 1:
The cable management system is made dynamic through the distribution arm that can rotate and extend, and the storage compartment that can open and close, allowing the cable to be actively managed during operation to prevent entanglement while maximizing workable area
Solution Approach 2:
The cable path is segmented into distinct sections: storage compartment in the rear, distribution arm in the middle, and connection point at the front, with each section having specific guides and management mechanisms to prevent interference
3Duration of action of moving object
If the reference rotor is mounted on the bearing frame, then the cable can be wound and unwound, but the machine structure becomes complex and space is consumed
Solution Approach 1:
The reference rotor is merged with the rear support structure of the bearing frame, integrating the cable winding function into the existing structural framework rather than adding a separate complex mounting system
Solution Approach 2:
The reference rotor is positioned in the rear part of the bearing frame, utilizing the vertical and lateral space in the rear section to accommodate the winding mechanism without interfering with front-mounted work equipment

In an innovative manner, the driving machine provides for the reference rotor, and the electric coil wound thereon, to be arranged in the central part of the bearing frame so that both the front part and the rear part of the bearing frame are frontally free and directly facing the external environment in order to accommodate, removably, both pieces of equipment for working the ground.
