Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple special models are manufactured to accommodate different load requirements and environments, then the adaptability to different requirements is improved, but the production effort and cost increase
Solution Approach 1:
The chassis is divided into modular components (side parts, cross members, connecting structures) that can be independently manufactured and then assembled. This segmentation allows the same basic modules to be reused across different models, reducing production effort while maintaining adaptability to different load requirements and environments.
Solution Approach 2:
The modular chassis components are designed with universal connecting structures that can accommodate various configurations. The same side parts and cross members can be used across multiple models by simply changing the arrangement or number of modules, enabling one set of basic parts to serve multiple functions and reduce manufacturing complexity.
2Adaptability or versatility
If multiple special models are manufactured to accommodate different load requirements and environments, then the adaptability to different requirements is improved, but the production cost increases
Solution Approach 1:
By segmenting the chassis into standardized modular components, the production process can be optimized for each module type. This reduces tooling costs and allows for more efficient manufacturing, thereby lowering production costs while still enabling adaptation to different environments through modular assembly.
Solution Approach 2:
The universal connecting structures and standardized modules enable the same components to be used across different environmental requirements, reducing the need for specialized parts for each environment. This component sharing significantly reduces production costs while maintaining the ability to adapt to various environments.
3Adaptability or versatility
If the chassis width is adjusted to meet specific requirements, then the adaptability to different requirements is improved, but the device complexity increases
Solution Approach 1:
The side parts are divided into multiple sections that can be independently adjusted. This segmentation allows the chassis width to be modified by simply adding or removing sections rather than redesigning the entire side part, thereby reducing structural complexity while maintaining width adjustability.
Solution Approach 2:
The connecting structures are designed to allow dynamic reconfiguration of the chassis width. The modular sections can be easily assembled or disassembled to change the overall width, making the chassis adaptable without requiring complex fixed structures for each width configuration.
4Adaptability or versatility
If the chassis length is adjusted to meet specific requirements, then the adaptability to different requirements is improved, but the device complexity increases
Solution Approach 1:
The cross members are segmented into modular units that can be combined in different quantities to achieve various chassis lengths. This segmentation allows length adjustment through simple repetition or reduction of standard modules, avoiding the need for complex custom-length components and reducing overall structural complexity.
