Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a piston-like arrangement with telescopic shafts and retention elements is used to transport the capsule, then the capsule transport function is achieved, but the construction complexity increases
Solution Approach 1:
The invention extracts and eliminates the complex telescopic shafts and retention elements from the capsule transport mechanism. Instead, it uses a simple base support that moves jointly with the injection disposition, relying on gravity for capsule ejection. This removes unnecessary components while maintaining the essential transport function.
Solution Approach 2:
Instead of using active retention elements to hold and transport the capsule, the invention inverts the approach by using a passive base support that simply moves with the injection disposition and allows gravity to handle capsule ejection. The system inverts from active retention to passive support with gravity-assisted ejection.
2Ease of manufacture
If a base support configured as longitudinal projections provided as a single piece with the injection disposition is used, then construction simplicity is improved, but the reliability of capsule support is worsened
Solution Approach 1:
The base support is designed to move dynamically jointly with the injection disposition rather than being a fixed single-piece structure. This dynamic configuration allows the base support to maintain proper positioning and support function throughout the injection and transport cycle, improving reliability while keeping the construction simple.
3Stability of the object's composition
If retention elements are used to limit the translation movement of the base support, then the base support positioning is controlled, but the device complexity increases
Solution Approach 1:
The invention removes the retention elements that limit base support translation. Instead of using additional components to control positioning, the base support is designed to naturally move jointly with the injection disposition through its structural connection, achieving stable positioning without extra complexity.
4Volume of moving object
If a compact force transmission mechanism is used to convert rotational motion into longitudinal movement, then the device size is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The force transmission mechanism is designed to convert rotational motion into longitudinal movement of the injection disposition through a self-contained arrangement. The mechanism serves itself by using the rotational input to directly drive the longitudinal movement without requiring additional precision components, achieving compactness while maintaining manufacturability.
