Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If rubber material is used for anti-vibration ring, then vibration reduction capability is improved, but installation position accuracy deteriorates
Solution Approach 1:
The anti-vibration ring is divided into two functional segments: a rubber anti-vibration body for vibration reduction and a rigid installation ring with identification structures and anti-rotation limit parts for precise positioning. This segmentation allows each part to optimize its specific function without compromising the other.
Solution Approach 2:
Asymmetric identification structures (such as identification notches, protrusions, or specific character markings) are introduced on the installation ring to create unique positioning features. These asymmetric features ensure the ring can only be installed in the correct orientation, preventing rotational misalignment while maintaining the rubber body's vibration damping properties.
2Object-generated harmful factors
If rubber material is used for anti-vibration ring, then noise reduction capability is improved, but installation reliability deteriorates
Solution Approach 1:
The patent merges two previously separate components into one integrated anti-vibration ring assembly: the rubber anti-vibration body and the rigid installation ring with positioning features. This combination ensures that the noise reduction capability of the rubber material is preserved while the integrated structure provides reliable installation through built-in identification and anti-rotation features.
Solution Approach 2:
Identification structures and anti-rotation limit parts are pre-formed on the installation ring during manufacturing. These preliminary positioning features guide correct installation before the rubber body is fully compressed or set, ensuring proper orientation and position are established in advance, thereby improving installation reliability.
3Stability of the object's composition
If deformation ability is provided in anti-vibration ring, then vibration absorption is improved, but positioning accuracy deteriorates
Solution Approach 1:
Different parts of the anti-vibration ring have different mechanical properties: the anti-vibration body is made of soft, deformable rubber material optimized for vibration absorption, while the installation ring is made of rigid material with high dimensional stability optimized for precise positioning. This local differentiation of material properties allows each region to perform its specific function optimally.
Solution Approach 2:
The anti-vibration ring is segmented into a deformable rubber body portion and a rigid installation ring portion. The rubber body can deform to absorb vibrations while the rigid installation ring maintains its shape and positioning features, ensuring accurate positioning is not compromised by the deformation characteristics of the rubber material.
