Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a unitary back frame is used, then the structural strength is improved, but the material cost and mold cost increase significantly
Solution Approach 1:
The back frame is divided into multiple separate assembling pieces instead of being a single unitary structure. This segmentation allows each piece to be manufactured with simpler, smaller molds, reducing mold cost while the assembled pieces form a complete frame structure that maintains structural strength.
2Stability of the object's composition
If a unitary back frame is used, then the structural integrity is improved, but the material consumption increases
Solution Approach 1:
By dividing the back frame into multiple assembling pieces, the total material consumption is reduced compared to a solid unitary frame. The segmented structure achieves the required structural integrity through the arrangement and connection of multiple pieces rather than requiring a single large continuous structure.
3Ease of manufacture
If a conventional back frame without conductive elements is used, then the manufacturing cost is reduced, but electromagnetic interference is not prevented
Solution Approach 1:
The back frame assembling pieces incorporate conductive materials or conductive coatings into the frame structure. This creates a composite structure that maintains the mechanical properties of the frame while adding electromagnetic shielding capability, preventing electromagnetic interference without significantly increasing manufacturing cost.
