Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single connection device is used for line-shaped components with different line diameters, then the number of different connection devices required is reduced and manufacturing complexity is simplified, but the hold and secure fit for each specific diameter may be inadequate
Solution Approach 1:
The connection device is segmented into multiple functional regions within the hose-receiving region: a seal-receiving region for sealing and a collet-chuck-receiving region for clamping. The clamping elements are further segmented as individual resilient components that can independently adapt to different line diameters, providing both versatility and reliable hold.
Solution Approach 2:
The hose-receiving region is designed with multi-functionality to accommodate different line-shaped components with varying diameters. The seal-receiving region and collet-chuck-receiving region work together to provide universal compatibility while maintaining secure fit through the resilient clamping elements that adapt to each specific diameter.
2Reliability
If multiple types of connection devices are used for different line diameters, then the secure fit and sealing for each diameter is optimized, but the production efficiency decreases and the number of tools required increases
Solution Approach 1:
The connection device incorporates a universal hose-receiving region that can accommodate different line diameters through its multi-functional design. The seal-receiving region with sealing element provides reliable sealing, while the collet-chuck-receiving region with resilient clamping elements ensures secure fit, all within a single device type.
Solution Approach 2:
The clamping elements are designed with elastic-resilient properties that allow them to change their clamping parameters (radial displacement) in response to different line diameters. This parameter adaptability enables a single device to maintain secure fit across various diameters without requiring multiple specialized tools.
3Adaptability or versatility
If the clamping elements are made elastically resilient, then the adaptability to different line diameters is improved and manufacturing is simplified, but the pull-out resistance may be reduced compared to rigid clamping
Solution Approach 1:
The clamping elements utilize elastic-resilient properties to dynamically adjust their clamping force parameters based on the inserted line diameter. When a line-shaped component is inserted, the resilient elements deform radially to accommodate the specific diameter, then exert sufficient radial clamping force to generate adequate pull-out resistance through friction and mechanical interlocking.
Solution Approach 2:
The resilient clamping elements are designed with curved or rounded features that allow them to flex and conform to the cylindrical shape of different line diameters. This curvature enables the elements to maintain continuous contact and generate effective frictional resistance against pull-out forces while adapting to various sizes.
4Manufacturing precision
If axial stops with different diameters are introduced, then the insertion depth control for different line diameters is improved and dead space is reduced, but the device complexity increases
Solution Approach 1:
The axial stopping function is segmented into multiple discrete axial stops with different diameters, each corresponding to specific line diameter ranges. This segmentation allows precise insertion depth control for different component types while keeping each individual stop structurally simple and easy to manufacture.
