Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing track conversion systems are used, then off-road capabilities are improved, but the system becomes bulky and difficult to install
Solution Approach 1:
The track assembly is divided into separate modular components including a frame, multiple shafts, and tracks that can be independently assembled and disassembled. This segmentation allows the system to be compact when not in use while providing full off-road capability when deployed, resolving the contradiction between adaptability and bulkiness.
Solution Approach 2:
The shafts are positioned within the frame structure, and the tracks are arranged to nest around the shafts when not in use. This nested configuration minimizes the overall volume of the track conversion system while maintaining its functional integrity for off-road operations.
2Adaptability or versatility
If existing track conversion systems are used, then off-road capabilities are improved, but installation becomes difficult
Solution Approach 1:
The track assembly is segmented into distinct components (frame, shafts, tracks) that can be independently handled and assembled. This segmentation simplifies the installation process by allowing each component to be positioned and secured separately, reducing the overall difficulty of installation while maintaining off-road capability.
Solution Approach 2:
The frame is pre-configured with openings and mounting features that facilitate the insertion of shafts and tracks during installation. This preliminary preparation of the frame structure guides the assembly process and reduces installation difficulty by eliminating the need for complex alignment procedures.
3Adaptability or versatility
If existing track conversion systems are used, then off-road capabilities are improved, but cost increases
Solution Approach 1:
By dividing the track conversion system into separate manufactured components (frame, shafts, tracks), each part can be produced using optimized manufacturing processes and then assembled. This segmentation allows for standardized production of individual components, reducing overall manufacturing cost while maintaining the full functionality for off-road operations.
Solution Approach 2:
The frame structure serves multiple functions: it provides the structural framework, contains the openings for wheel engagement, supports the shafts, and guides the tracks. This multi-functionality reduces the total number of components needed, simplifying manufacturing and reducing cost while preserving off-road capabilities.
