Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If modular bases are used to create large surface dimensions, then the base can accommodate different sheet material sizes, but discontinuities between modules manifest causing poor flatness
Solution Approach 1:
The base is divided into multiple modular elements that can be assembled together to create large surface areas. Each module can be manufactured separately with standard tolerances, then joined using leveling legs to achieve overall flatness without requiring extremely precise manufacturing of each individual module.
Solution Approach 2:
The base incorporates adjustable leveling legs with elastic elements that allow dynamic adjustment of each module's height position. This enables the base to adapt to surface irregularities and achieve perfect flatness through mechanical adjustment rather than relying solely on manufacturing precision.
2Manufacturing precision
If high precision structure is used to achieve perfect flatness, then cutting precision is improved, but the cost and complexity of the base structure increases
Solution Approach 1:
Instead of using a rigid high-precision structure, the invention employs adjustable leveling legs with elastic elements that allow the base to achieve and maintain flatness through simple mechanical adjustment. This dynamic adjustment capability replaces the need for complex high-precision manufacturing.
Solution Approach 2:
The base allows adjustment of the height parameter of each leg independently, enabling the operator to compensate for surface irregularities and achieve the desired flatness parameter without requiring the entire structure to be manufactured with high precision.
3Device complexity
If the base is designed as a static support surface, then structural simplicity is maintained, but the work surface cannot slide on it
Solution Approach 1:
The base incorporates rollers within its modular structure that enable the work surface to slide over it dynamically. This maintains the simplicity of the base structure while adding the versatility of supporting both stationary and moving work surfaces depending on the application requirements.
