Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If segments have constant cross section throughout their length, then production costs are reduced and manufacturing flexibility is improved, but mechanical resistance and rigidity are compromised due to inability to optimize for varying stresses
Solution Approach 1:
The segment is divided into multiple tracts (first tract, second tract, connection tract) with different cross-sectional characteristics. Each tract is optimized for its specific functional requirements while being manufactured as part of a single composite component, thus achieving stress optimization without sacrificing manufacturing efficiency.
Solution Approach 2:
Different regions of the segment (tracts) are given different cross-sectional properties tailored to their specific stress conditions. The first tract has one cross-sectional configuration, the second tract has another, and the connection tract bridges them, allowing each zone to have the optimal properties for its mechanical environment.
2Strength
If segments have varying cross section along their length, then mechanical resistance is optimized for different stresses, but production costs increase and manufacturing complexity increases
Solution Approach 1:
The segment is manufactured as a composite material structure with multiple tracts of different cross-sections. The composite construction allows integration of varying geometries within a single manufacturing process, achieving mechanical optimization without requiring multiple separate components or complex assembly steps that would increase cost.
3Strength
If traditional metal material is used for arm segments, then mechanical strength is achieved, but overall weight increases significantly
Solution Approach 1:
The patent replaces traditional metal materials with composite materials for the arm segments. Composite materials provide comparable or superior mechanical strength and rigidity while significantly reducing weight, enabling the articulated arm to achieve greater heights and lengths with reduced overall mass.
Solution Approach 2:
The arm is divided into multiple articulated segments that can be independently optimized. Each segment uses composite material construction with tailored cross-sections, allowing weight reduction while maintaining the strength required for each specific position and function in the articulated system.
4Adaptability or versatility
If molded segments are used instead of traditional construction, then production flexibility and adaptability improve, but achieving variable section sizes becomes more difficult
Solution Approach 1:
The molded segment construction uses composite material technology that enables integration of multiple cross-sectional configurations within a single molding process. This allows the production of segments with varying section sizes while maintaining the advantages of molded construction, including production flexibility and adaptability to different vehicle requirements.
