Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single battery pack is used in the base assembly, then the device complexity is reduced, but the operational capacity and power distribution efficiency deteriorate
Solution Approach 1:
The battery system is divided into two separate battery packs: a base assembly battery pack and a turntable assembly battery pack. This segmentation allows independent power management for each assembly, enabling the turntable to operate independently and improving overall operational capacity without significantly increasing complexity.
2Adaptability or versatility
If the turntable assembly is rotatably coupled to the base assembly through a slip ring transmission, then the operational versatility is improved, but the reliability of electrical connection deteriorates
Solution Approach 1:
The electrical connection system is segmented into two independent power sources: the base assembly battery pack provides power to base components, while the turntable assembly battery pack provides power to turntable components. This eliminates the need for continuous electrical connections through the rotating slip ring, maintaining reliability while preserving rotational versatility.
3Use of energy by moving object
If the base assembly batteries charge the turntable batteries through the slip ring transmission, then the power distribution efficiency is improved, but the reliability of the charging system deteriorates
Solution Approach 1:
The charging system is segmented into two independent battery packs that can be charged separately. The base assembly battery pack and turntable assembly battery pack each have independent charging capabilities, eliminating the need for power transfer through the rotating slip ring connection, thus maintaining charging reliability while preserving power distribution efficiency.
4Ease of operation
If the operator station is accessible during operation, then the ease of operation is improved, but the security deteriorates
Solution Approach 1:
The operator station is designed with a deployable mechanism that can be dynamically adjusted between an accessible position during operation and a restricted position when not in use. This dynamic configuration allows the operator station to transition between open and closed states, providing ease of operation when needed while preventing unauthorized access when the lift is stationary.
