Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fiber composite materials are used to form document layers for protecting electronic circuits, then mechanical protection and stability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent divides the document structure into distinct functional layers: a base layer made of flexible material (polycarbonate or polyimide) and separate fiber composite reinforcement layers positioned strategically to protect electronic circuits. This segmentation allows the flexible base layer to provide mechanical flexibility while the discrete fiber composite layers provide targeted reinforcement only where needed for circuit protection, rather than requiring the entire document to be made of complex fiber composite material.
Solution Approach 2:
The fiber composite material is applied locally only in specific regions where electronic circuits are located, rather than throughout the entire document. This localized application provides mechanical protection precisely where needed while maintaining the overall flexibility of the document and reducing the total amount of fiber composite material required, thereby lowering manufacturing complexity and cost.
2Reliability
If fiber composite materials are used to form document layers for protecting electronic circuits, then mechanical protection and stability are improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the document into a flexible base layer and separate reinforcement layers, the patent enables independent manufacturing and optimization of each layer. The flexible base layer can be produced using cost-effective processes, while fiber composite reinforcement is added only where necessary, reducing overall material costs and simplifying the manufacturing process compared to using fiber composite material throughout the entire document.
Solution Approach 2:
The localized application of fiber composite material reduces material consumption and associated costs. By reinforcing only the specific areas containing electronic circuits rather than the entire document, the patent achieves necessary mechanical protection while minimizing manufacturing expenses.
3Stability of the object's composition
If electronic circuits are integrated into flexible plastic documents, then document flexibility is maintained, but mechanical protection of circuits is insufficient
Solution Approach 1:
The patent segments the document structure into a flexible base layer and separate reinforcement layers. The base layer maintains document flexibility while the discrete fiber composite reinforcement layers provide targeted mechanical protection for electronic circuits, resolving the contradiction between flexibility and protection.
Solution Approach 2:
The patent creates a composite structure combining flexible plastic materials (polycarbonate or polyimide) with fiber composite reinforcement materials. This composite construction allows the document to maintain the flexibility of the plastic base layer while the integrated fiber composite layers provide enhanced mechanical protection for embedded electronic circuits.
