Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional holding devices are used for energy stores, then the energy store can be held on the frame, but the frame weight is high and stiffness is insufficient
Solution Approach 1:
The carrier element is integrated into the frame's load path, merging the holding device structure with the frame structure itself. This integration eliminates separate stiffening components and allows the frame to directly bear and distribute loads from the energy store, simultaneously reducing weight and maintaining stiffness.
Solution Approach 2:
The holding device is segmented into distinct functional units: the carrier element integrated into the load path for structural support, and the support unit with form-fit extensions for precise positioning. This segmentation allows each component to be optimized for its specific function while working together to solve the weight-stiffness contradiction.
2Reliability
If conventional holding devices are used for energy stores, then the energy store can be held on the frame, but theft protection is insufficient
Solution Approach 1:
The carrier element is merged with the frame structure through integration into the load path, creating a unified structural system that is inherently more secure. This integration makes removal more difficult without requiring additional complex locking mechanisms, thus improving theft protection while avoiding increased device complexity.
3Weight of moving object
If the carrier element is integrated into the load path, then weight is reduced and stiffness is enhanced, but the complexity of integration increases
Solution Approach 1:
The integration is segmented into modular components: the carrier element with its specific geometry for load path integration, and the support unit with form-fit extensions for positioning. This segmentation allows for standardized manufacturing processes and simplifies assembly, reducing the overall complexity despite the integrated design.
4Stability of the object's composition
If support elements are added to secure the energy store transversely, then stability is improved, but device complexity increases
Solution Approach 1:
The support elements with form-fit extensions are merged with the carrier element structure, creating a unified component that provides both structural support and transverse positioning. This integration eliminates the need for separate positioning mechanisms, achieving enhanced stability without proportionally increasing device complexity.
