Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cut-out portions and plastic deformation are used for fixation, then the claw collar achieves secure attachment, but the manufacturing process becomes complex and costly
Solution Approach 1:
The base body is divided into a first part and a second part that can be separately manufactured and then assembled together through snap-fastening. This segmentation allows each part to be produced using simpler, more economical processes while maintaining secure attachment through the interlocking projection-orifice mechanism.
Solution Approach 2:
Snap-fastening means consisting of projections and orifices serve as an intermediary mechanism between the first and second parts of the base body. This intermediary system enables secure fixation without requiring complex cutting and bending operations, thus reducing manufacturing complexity while maintaining attachment security.
2Reliability
If complex cutting and bending operations are used for fixation, then secure attachment is achieved, but manufacturing time and cost increase
Solution Approach 1:
By segmenting the base body into two parts with snap-fastening interfaces, the manufacturing process avoids time-consuming cutting and bending operations. Each part can be manufactured independently using simpler, faster processes, thereby improving productivity while maintaining fixation strength through the snap-fit mechanism.
Solution Approach 2:
The snap-fastening mechanism allows the two parts to self-align and self-secure during assembly through the engagement of projections with orifices. This self-service mechanism eliminates the need for complex manual or automated cutting and bending operations, significantly improving manufacturing efficiency while ensuring reliable fixation.
3Stability of the object's composition
If integral construction with complex forming operations is used, then structural integrity is maintained, but manufacturing cost increases
Solution Approach 1:
The base body is segmented into two separable parts that can be manufactured independently using cost-effective processes. The snap-fastening connection between parts maintains structural integrity during use, providing a balance between manufacturability and structural stability that reduces overall manufacturing cost.
Solution Approach 2:
The two separately manufactured parts are merged through snap-fastening means to form the complete base body. This merging approach allows each part to be produced using simpler, cheaper processes while the combined structure maintains the necessary structural integrity for the claw collar's application.
