Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional level adjustment mechanisms are used for worktables, then the device complexity is reduced, but the manufacturing precision and measurement precision of the level adjustment are insufficient
Solution Approach 1:
The adjusting device is divided into multiple independent adjusters, each with its own threaded aperture and fastening member. This segmentation allows for precise individual adjustment of each worktable corner while maintaining overall system manageability and accuracy.
Solution Approach 2:
The invention replaces conventional mechanical level adjustment mechanisms with a threaded aperture and fastening member system. This substitution provides finer control over adjustment precision while maintaining mechanical simplicity through the use of standard threaded fasteners.
2Reliability
If conventional adjustment mechanisms are used, then the device structure is simpler, but the reliability and stability of the level adjustment under varying conditions is insufficient
Solution Approach 1:
The worktable is equipped with receptacles positioned to receive the fastening members before final assembly. This preliminary positioning ensures that the adjustment mechanism is pre-configured for stable engagement, preventing shifts or deformations under varying operational conditions.
Solution Approach 2:
The invention uses threaded apertures with adjustable fastening members that allow for precise control of engagement parameters. By changing the threaded engagement depth and fastening torque, the system achieves reliable and stable level adjustment that resists deformation under various loads and conditions.
3Measurement precision
If conventional adjustment mechanisms are used, then the ease of manufacture is improved, but the measurement precision and accuracy of level adjustment is insufficient
Solution Approach 1:
The adjusting device uses universal threaded apertures and standard fastening members that can be manufactured using conventional machining processes. This multi-functional approach allows the same basic components to provide both precise measurement capability and easy manufacturability through standardization.
Solution Approach 2:
The invention employs multiple identical adjusters with the same threaded aperture and fastening member design. This copying approach enables precise level measurement through replication of proven, easily manufacturable components, ensuring consistency and accuracy across all adjustment points.
