Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the legs of the transport apparatus are installed independently of the bed, then vibrations are not transmitted to the bed and workpiece processing accuracy is maintained, but the transport apparatus and machine tool may be displaced relatively to each other
Solution Approach 1:
A connecting plate is introduced as an intermediary component between the bed and the legs of the transport apparatus. This plate serves as a mediator that allows controlled interaction between the two structures, enabling both vibration isolation and positional stability through its elastic deformation capability.
Solution Approach 2:
The connecting plate utilizes elastic deformation as a parameter change mechanism. By allowing the plate to deform elastically under vibrational loads, the system dynamically adjusts its mechanical properties to absorb vibrations while maintaining structural connectivity and positional relationship between the bed and transport apparatus.
2Stability of the object's composition
If the legs of the transport apparatus are mounted on the bed, then relative displacement between transport apparatus and machine tool is prevented, but vibrations are transmitted to the bed and workpiece processing accuracy deteriorates
Solution Approach 1:
The connecting plate acts as an intermediary that decouples the direct rigid connection between the bed and transport apparatus legs. This intermediary structure allows the system to maintain positional stability while isolating vibrations through the plate's elastic deformation characteristics.
Solution Approach 2:
The elastic deformation capability of the connecting plate converts the harmful vibrational energy into beneficial elastic strain energy. This allows the system to absorb and dissipate vibrations that would otherwise be transmitted to the bed, while the plate's rigidity maintains the necessary positional relationship for accurate workpiece transfer.
