Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a method of manufacturing a model using paper with a scheme of tightly fitting a plurality of pieces in grooves is used, then the model can be manufactured with simple materials, but the model cannot be delicately manufactured and durability is significantly degraded
Solution Approach 1:
The model is divided into multiple cross-sectional pieces at specific positions along the object's axis. Each piece represents a cross-section of the object at a specific position, and these segmented pieces are assembled together to form the complete three-dimensional model. This segmentation allows for easier manufacturing of individual pieces while maintaining the ability to create delicate, accurate representations when assembled.
Solution Approach 2:
The invention transitions from two-dimensional paper pieces to three-dimensional structured pieces with grooves and protrusions. By adding the third dimension through vertical grooves and corresponding protrusions, the pieces gain structural integrity and precise alignment capabilities, resolving the contradiction between ease of manufacture and manufacturing precision.
2Ease of manufacture
If a method of manufacturing a model using paper with a scheme of tightly fitting a plurality of pieces in grooves is used, then the model can be manufactured with simple materials, but durability is significantly degraded so that the model is damaged due to weak external force
Solution Approach 1:
The invention uses composite structural elements within each piece, combining horizontal layers with vertical grooves and protrusions. This composite structure creates interlocking joints that significantly enhance the overall strength and durability of the model while maintaining ease of manufacture through modular assembly.
Solution Approach 2:
By segmenting the model into multiple pieces with interlocking grooves and protrusions, the structure gains cumulative strength through the assembly of many small, precisely fitted components. The segmented design allows for better stress distribution throughout the model, improving durability compared to solid-piece constructions.
3Manufacturing precision
If three-dimensional computer modeling and contour extraction are used to manufacture a model, then a delicate shape similar to the real object can be achieved, but the device complexity increases
Solution Approach 1:
The invention replaces complex mechanical modeling devices with computer-based three-dimensional modeling and digital contour extraction. By using software to create and extract contours from digital models, the process achieves high manufacturing precision while reducing physical device complexity. The digital workflow eliminates the need for complex physical jigs, fixtures, and manual measurement tools.
