Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If materials are used in high-precision products, then the products can be manufactured with required functionality, but the volume change characteristics of materials cause large errors leading to product scrap
Solution Approach 1:
The structure is divided into multiple structure bodies arranged in layers with staggered connections, creating a segmented framework that can independently manage expansion in different directions. This segmentation allows the structure to accommodate material volume changes without compromising overall precision.
Solution Approach 2:
The patent employs a composite structure combining multiple structure bodies with different geometric configurations and materials having different expansion coefficients. By strategically selecting and arranging these composite elements, the overall structure achieves a controlled effective expansion coefficient that minimizes dimensional errors.
2Ease of manufacture
If traditional single-layer structures are used, then the structure is simple to manufacture, but the expansion coefficient cannot be adjusted and leads to precision errors
Solution Approach 1:
The structure is divided into multiple structure bodies arranged in layers with staggered connections, creating a segmented framework that can independently manage expansion in different directions. This segmentation allows the structure to accommodate material volume changes without compromising overall precision.
Solution Approach 2:
The patent enables adjustment of the effective expansion coefficient by modifying structural parameters such as the arrangement configuration, spacing, and material properties of the structure bodies. This allows optimization of dimensional stability while maintaining manufacturability through standardized modular components.
3Volume of moving object
If structure bodies are arranged closely to maintain compactness, then the structure size is reduced, but the expansion errors are amplified
Solution Approach 1:
The structure is divided into multiple structure bodies arranged in layers with staggered connections, creating a segmented framework that can independently manage expansion in different directions. This segmentation allows the structure to accommodate material volume changes without compromising overall precision.
Solution Approach 2:
The patent transitions from a single-layer arrangement to a multi-layer three-dimensional configuration with staggered connections. This dimensional change allows expansion to be distributed across multiple layers and directions, reducing the amplification of errors while maintaining a compact overall volume.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composite structure effectively manages thermal and moisture expansion, minimizing errors and maintaining precision by adjusting the overall expansion coefficient of the integrated structure.
Implementation Method 1
the adjustment bodies are configured to adjust gap widths between adjacent first structure bodies and gap widths between adjacent second structure bodies according to expansion coefficients of the adjustment bodies, so as to adjust an expansion coefficient of the integrated structure
Implementation Method 2
the expansion coefficients are coefficients of thermal expansion or coefficients of moisture expansion
