Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the sock liner designing apparatus focuses on improving the fit of the foot in the footwear, then the fit function is improved, but other desired functions such as cushioning, stability, and grip are neglected
Solution Approach 1:
The designing apparatus is enhanced to perform multiple functions: it calculates the three-dimensional void based on foot shape data, adjusts design data according to user-selected footwear functions (cushioning, stability, grip), and generates comprehensive design information. This multi-functional approach allows the same apparatus to address both fit precision and various footwear functions simultaneously.
Solution Approach 2:
The apparatus dynamically adjusts design parameters (material properties, structure, cup height, thickness, compressibility) based on the calculated three-dimensional void and user-selected functions. By changing these parameters according to different function requirements, the system can optimize both fit precision and other desired functions like cushioning and stability.
2Reliability
If the sock liner is designed to keep the foot in a desired state for improved fit, then the fit function is enhanced, but the apparatus becomes too focused on fit and neglects other functions
Solution Approach 1:
The design process is segmented into distinct steps: (1) acquiring foot shape data, (2) calculating the three-dimensional void, (3) adjusting design data based on user-selected functions, and (4) generating final design information. This segmentation allows the apparatus to systematically address fit reliability through the void calculation while separately optimizing for other functions through the design data adjustment step.
Solution Approach 2:
The apparatus incorporates user feedback by receiving input on desired footwear functions (cushioning, stability, grip) and using this feedback to adjust the design data. This feedback mechanism ensures the apparatus maintains focus on fit reliability through the three-dimensional void calculation while simultaneously responding to user needs for other functions, preventing excessive focus concentration on any single aspect.

AI summary
A sock liner designing apparatus, a sock liner designing method and a recording medium for a recording program are provided that are used to design sock liners that enable functions of footwear desired by a user to be attained when the user wears the footwear. A sock liner designing apparatus includes: an input circuitry that receives an input of measured foot data; a processor that calculates design data of a sock liner based on the foot data received through the input circuitry; and an output circuitry that outputs the design data calculated by the processor. The processor adjusts the design data based on a difference between received footwear functions and footwear data.
