Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If supporting columns are inserted into holes of metal mesh without positioning features, then the assembly process is simple, but displacement occurs during insertion causing imprecise positioning
Solution Approach 1:
Positioning portions (such as ridges or protrusions) are pre-formed on the supporting columns before insertion. These positioning features are prepared in advance to engage with corresponding holes in the metal mesh, ensuring that the columns are automatically guided to the correct positions during assembly without requiring complex alignment procedures.
Solution Approach 2:
The positioning portions act as intermediary elements between the supporting columns and the metal mesh holes. These intermediate features facilitate the connection by providing a mechanical interface that prevents displacement and rotation, enabling simple insertion while achieving precise positioning through the geometric constraint provided by the positioning portions.
2Productivity
If supporting columns are inserted without positioning features, then the assembly process is fast, but rotation occurs during insertion reducing yield rate
Solution Approach 1:
Positioning portions are pre-formed on the supporting columns before assembly. These features are prepared in advance to engage with corresponding holes in the metal mesh, ensuring that the columns are automatically guided to the correct positions during assembly without requiring complex alignment procedures.
Solution Approach 2:
The positioning portions introduce asymmetric geometric features on otherwise symmetric cylindrical columns. This asymmetry creates a unique orientation for insertion, preventing rotation during the assembly process. The asymmetric shape of the positioning portions ensures that only one rotational orientation allows proper engagement with the metal mesh holes.
3Manufacturing precision
If supporting columns are precisely positioned using positioning portions, then positioning precision is improved, but the structure becomes more complex
Solution Approach 1:
The supporting column is segmented into distinct functional features: the main cylindrical body for structural support and the positioning portions for precise location. This segmentation allows each feature to perform its specific function independently, achieving precise positioning without requiring complex overall structure. The positioning portions are discrete features added to the otherwise simple cylindrical column.
Solution Approach 2:
Instead of making the entire supporting column structure complex, the positioning portions are localized features applied only where needed for positioning. The majority of the column maintains its simple cylindrical form for structural integrity, while local positioning features are added only at specific locations to achieve precise positioning without global structural complexity.
