Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing methods for structures like shoe insoles using three-dimensional modeling equipment face challenges in achieving varying elasticity across different parts without increasing the complexity of the two-dimensional moving path of the nozzle, which can lead to discontinuity and longer forming times.
Innovation Solution
The method involves using a three-dimensional modeling equipment that alternately laminates linear structures with different thicknesses to create first and second elastic regions, allowing for continuous and smooth changes in elasticity by adjusting the thickness of the linear resin ejected from the nozzle, while maintaining a constant moving pitch, thereby avoiding the need to change the arrangement interval of the linear resins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the arrangement interval of linear resins is changed to vary elasticity across different parts, then elasticity distribution is improved, but the two-dimensional moving path of the nozzle becomes complex and discontinuous
Solution Approach 1:
The patent applies local quality by varying the thickness of linear resin at different locations while keeping the arrangement interval constant. The thickness is controlled by adjusting the ejection amount of linear resin from the nozzle, allowing different parts of the formed body to have different elasticity (first elastic region with greater thickness and second elastic region with lesser thickness) without changing the nozzle's moving path or arrangement interval
2Adaptability or versatility
If the arrangement interval of linear resins is changed to vary elasticity, then elasticity distribution is improved, but forming time increases
Solution Approach 1:
The patent changes the parameter of linear resin thickness (via ejection amount) rather than the arrangement interval to achieve varying elasticity. This allows the nozzle to maintain a constant moving pitch and simple two-dimensional moving path, thereby reducing forming time while still creating different elastic regions through controlled variations in resin thickness
3Adaptability or versatility
If the thickness of linear resin is varied to change elasticity, then elasticity distribution is improved, but the complexity of controlling the nozzle increases
Solution Approach 1:
The patent varies the thickness of linear resin by controlling the ejection amount from the nozzle while maintaining a constant moving pitch. This approach simplifies nozzle control compared to changing arrangement intervals, as it only requires adjusting the ejection parameters rather than reprogramming the entire moving path or pitch, thereby achieving elasticity distribution with manageable control complexity
