Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cap is used to seal and protect the medical device nozzle, then leakage and contamination are prevented, but the cap tends to become partially or fully removed during transport and storage
Solution Approach 1:
The coupling members are designed to be elastically deformable, allowing dynamic adjustment during attachment and removal. The elastic deformation enables the cap to be easily attached by deforming the coupling members outward, and securely locked when released, while still allowing intentional removal when force is applied in the removal direction.
Solution Approach 2:
The rigidity parameter of the coupling members is optimized to enable elastic deformation within a specific range. This allows the coupling members to deform elastically during attachment and removal operations, providing both ease of operation and secure connection stability during transport and storage.
2Stability of the object's composition
If a cap is designed to be securely attached to the medical device, then connection stability is improved, but the cap becomes difficult for users to secure and remove
Solution Approach 1:
The coupling members are designed to be elastically deformable, allowing dynamic adjustment during attachment and removal. The elastic deformation enables the cap to be easily attached by deforming the coupling members outward, and securely locked when released, while still allowing intentional removal when force is applied in the removal direction.
Solution Approach 2:
The rigidity parameter of the coupling members is optimized to enable elastic deformation within a specific range. This allows the coupling members to deform elastically during attachment and removal operations, providing both ease of operation and secure connection stability during transport and storage.
3Strength
If the cap is made from a rigid material, then structural strength is improved, but the cap becomes difficult to deform for securement
Solution Approach 1:
Different parts of the cap are made with different mechanical properties. The cap body is made from a relatively rigid material for structural strength, while the coupling members are made from an elastically deformable material that can be easily deformed during attachment and removal operations.
Solution Approach 2:
The cap is constructed using composite materials with different rigidity characteristics. The cap body uses a rigid material for overall structural strength, while the coupling members use an elastically deformable material that can be easily deformed during attachment and removal, combining the benefits of both rigid and flexible materials.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cap assembly maintains a robust connection during transport, storage, and usage, ensuring easy securement and removal, thus enhancing the user experience by preventing leakage and contamination.
Implementation Method 1
At least a portion of one or more of the cap and the connection element is elastically deformable. Movement of the cap in a first direction relative to the connection element causes one or more of the cap and the connection element to elastically deform to secure the cap to the connection element.
