Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional gripping device is used, then the device structure is simple, but the device cannot easily place objects on conveyance destination stages
Solution Approach 1:
The patent implements a movable stage that can slide relative to the holder, transforming the static gripping device into a dynamic system. The stage moves in the direction away from the holder to enable easy placement of objects on conveyance destination stages, while the rail mechanism provides guided motion to maintain structural control despite the increased mobility.
Solution Approach 2:
The movable stage acts as an intermediary component between the holder and the object to be conveyed. It facilitates the transfer of the object to the conveyance destination stage by sliding underneath the contact members, enabling easy placement without requiring complex manipulation of the contact members themselves.
2Measurement precision
If contact members are used to hold objects, then the object can be securely gripped, but precise alignment and gentle handling are difficult to achieve
Solution Approach 1:
The gripping function is segmented into two independent parts: the contact members for gripping the object and the movable stage for positioning and alignment. This segmentation allows the contact members to focus on secure gripping while the movable stage handles precise alignment and gentle placement, reducing harmful forces on the object.
Solution Approach 2:
The movable stage serves as an intermediary that receives the gripped object from the contact members and transfers it to the conveyance destination stage. This intermediary mechanism enables precise alignment and gentle handling during the transfer process, protecting the object from excessive forces while maintaining alignment precision.
3Use of energy by moving object
If the movable stage moves toward the holder, then elastic energy is stored, but the device requires more complex drive mechanism
Solution Approach 1:
The elastic body provides self-service by automatically storing elastic energy when the movable stage moves toward the holder, without requiring additional control mechanisms. This energy storage capability is passively achieved through the elastic deformation of the body, reducing the complexity of the drive mechanism while enabling energy recovery and assisted motion control.
