Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a segmented clamping ring connection is used to secure the crusher jacket, then the fastening is secure, but the assembly becomes complex and requires many parts
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated clamping ring that wraps around the crusher jacket. Instead of using segmented rings with multiple connection points, one continuous clamping ring performs the entire fastening operation, reducing the number of parts while maintaining secure attachment.
Solution Approach 2:
The clamping ring is designed to perform multiple functions simultaneously: it provides mechanical fastening, allows for adjustable positioning, and enables easy release. The single component serves as both the fastening mechanism and the adjustment mechanism, eliminating the need for separate segments and connection elements.
2Reliability
If threaded connections with screw receptacles are used to fasten the crusher jacket, then the fastening can be secure, but the threaded connection is susceptible to damage
Solution Approach 1:
The patent replaces the threaded mechanical connection system with a friction-based clamping system. The clamping ring applies radial pressure directly to the crusher jacket body rather than engaging threaded receptacles, eliminating the vulnerable threaded interfaces that are prone to damage from misalignment or over-tightening.
Solution Approach 2:
The clamping ring acts as an intermediary element that distributes fastening forces around the entire circumference of the crusher jacket rather than concentrating forces at discrete threaded connection points. This distributed loading reduces stress concentrations and prevents localized damage.
3Reliability
If multiple fastening components are used to ensure secure attachment, then the fastening is reliable, but the assembly and disassembly process becomes time-consuming
Solution Approach 1:
While the clamping ring itself is continuous, the design incorporates segmented adjustment mechanisms that allow independent positioning of the clamping force. This enables rapid adjustment without disassembling the entire fastening system, reducing assembly time while maintaining secure attachment through the continuous ring structure.
Solution Approach 2:
The clamping ring system incorporates dynamic adjustment capabilities that allow the fastening mechanism to be quickly tightened or loosened in response to operational requirements. The design enables rapid transition between assembly and disassembly states through simple mechanical adjustments rather than requiring complete component removal.
