Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tailored body structures are used for different vehicle types, then vehicle assembly can be performed, but production time and material usage increase
Solution Approach 1:
The patent applies universality by using standardized body structures that can serve multiple vehicle assembly types. Instead of creating tailored body structures for each vehicle type, the invention uses a universal body structure design that can be adapted through deformation treatment to meet different vehicle requirements, thereby reducing production time and complexity
Solution Approach 2:
The patent employs parameter changes by treating deformation regions of standardized body structures to modify their mechanical properties. Through controlled deformation treatment, the same body structure can be adapted to different vehicle types by changing the deformation characteristics of specific regions, eliminating the need for entirely different body structures for each vehicle type
2Adaptability or versatility
If tailored body structures are used for different vehicle types, then vehicle assembly can be performed, but material usage increases
Solution Approach 1:
The patent eliminates material waste by using universal body structures that can be adapted to multiple vehicle types through deformation treatment. Instead of manufacturing separate tailored body structures for each vehicle type, the same body structure is reused and modified, significantly reducing material consumption
Solution Approach 2:
The invention changes the deformation parameters of standardized body structures to create different vehicle types from the same base material. This approach avoids the need to manufacture additional tailored body structures, thereby reducing material usage and associated waste
3Extent of automation
If robotic devices handle various body structures, then automatic assembly can be performed, but device complexity increases
Solution Approach 1:
The patent simplifies robotic device complexity by standardizing body structure dimensions and deformation region locations. This standardization allows a single robotic device configuration to handle multiple vehicle assembly types, eliminating the need for complex reconfiguration mechanisms and reducing overall device complexity
Solution Approach 2:
The invention enables automatic assembly by defining standardized deformation region parameters that can be programmatically controlled. The robotic devices can automatically adjust deformation treatment parameters based on the target vehicle assembly type, simplifying the control logic and reducing device complexity compared to handling entirely different body structures
4Adaptability or versatility
If standardized body structures with deformation treatment are used, then multiple vehicle types can be produced, but assembly process complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining deformation region locations and characteristics in the standardized body structure design. This allows the deformation treatment to be performed as a routine, predictable step in the assembly process, reducing overall process complexity compared to creating tailored body structures for each vehicle type
Solution Approach 2:
The invention manages assembly process complexity by standardizing the parameters of deformation regions. The controlled variable approach, where deformation treatment parameters are adjusted based on the target vehicle assembly type, creates a systematic and manageable process rather than requiring complex customization for each vehicle type
