Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If powder of highly conductive substances is formed into a linear shape, then the material can be used as electric cable material, but the physical properties change and conductivity lowers
Solution Approach 1:
The patent uses a hollow body (flexible shell structure) to accommodate the powder material during processing. The hollow body maintains the linear shape while allowing the powder inside to retain its original physical properties, preventing conductivity loss during the forming process
Solution Approach 2:
The invention segments the material system into three distinct parts: the hollow body structure, the powder material inside, and the sublime substance coating. This segmentation allows each component to perform its specific function independently, with the hollow body providing structural support while the powder maintains its conductive properties
2Adaptability or versatility
If powder of insulating substances is formed into a linear shape, then the material can be used as optical fiber material, but physical properties change
Solution Approach 1:
The hollow body acts as a protective shell that accommodates the insulating powder material during the linear forming process. This shell structure enables the material to be shaped into linear forms suitable for optical fibers while maintaining the original physical properties of the powder
Solution Approach 2:
The hollow body serves as an intermediary structure between the powder material and the external environment. It allows the powder to be transported and formed into linear shapes without direct exposure to processing conditions that would alter its physical properties
3Quantity of substance
If the hollow body is compressed to compact the powder, then the powder density increases, but the hollow body structure may deform
Solution Approach 1:
The patent applies controlled compression force parameters to the hollow body, optimizing the balance between compacting the powder inside and maintaining the hollow body's structural integrity. The compression is applied gradually and uniformly to achieve dense powder packing without excessive deformation of the outer shell

AI summary
A method for manufacturing a linear member reduces changes in the physical properties of a substance serving as a material for the linear member that may be caused when the substance is formed into a linear shape from powder. A manufacturing device usable for the method for manufacturing a linear member is a device for manufacturing a linear member having a predetermined function. The device includes a compressor. The compressor compresses, from an outer periphery of an elongated hollow body (9), the hollow body (9) accommodating powder of a substance having the predetermined function at an inner periphery of the hollow body (9) to compact the powder to allow the powder to substantially show the predetermined function. The linear member can be freely deformed while linearly accommodating the powder and maintaining the powder compacted. This structure can reduce changes in the physical properties of a substance in the linear member having the predetermined function that may be caused when the substance is formed into a linear shape from the powder.
