Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydraulic pump and cylinder part are joined by a hydraulic hose, then the device can function, but the total weight increases and portability degrades
Solution Approach 1:
The patent integrates the hydraulic pump and cylinder part into a single unified device structure, eliminating the need for separate hydraulic hoses and external power sources. This merging of components reduces the total weight while maintaining full hydraulic functionality for bolt hole alignment operations.
2Power
If a generator or power cord is used to operate the device, then the hydraulic pump can function, but the operation range is limited and noise is generated
Solution Approach 1:
The device incorporates an integrated battery pack that provides self-contained power supply for the hydraulic pump, eliminating the need for external generators or power cords. This self-service power system enables operation in remote outdoor locations and high places without commercial power supply, significantly expanding the operation range while reducing noise.
3Weight of moving object
If the device structure is made compact, then portability improves, but the hydraulic system may become more complex
Solution Approach 1:
The patent combines the hydraulic pump, cylinder part, power supply, and control mechanisms into a single integrated compact unit. This merging approach simplifies the overall system architecture by eliminating external connections and separate components, thereby improving portability without increasing hydraulic system complexity.
