Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional modeling equipment for manufacturing shoe insoles faces challenges in simplifying the nozzle's moving path complexity when forming regions with different elasticity, improving usability based on pressure distribution, preventing the peeling of covering layers from base layers, and maintaining optimal shapes for users.
Innovation Solution
The solution involves creating a structure with first and second elastic regions using linear resin, where the resin thickness differs between regions, and a manufacturing method that acquires pressure distribution data to generate forming data for the nozzle's path and thickness, ensuring the covering layer is impregnated into the base layer for strong bonding, and using shape memory materials for adaptable designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the arrangement interval of linear resin is changed between different elastic regions to achieve varying elasticity, then the usability of the structure is improved, but the moving path complexity of the nozzle increases
Solution Approach 1:
The patent applies local quality by varying the thickness of the linear resin in different regions (first elastic region with greater thickness, second elastic region with lesser thickness) while maintaining a uniform arrangement interval. This allows different elasticity characteristics in different regions without complicating the nozzle moving path, as the nozzle follows a consistent grid pattern throughout the forming process.
2Adaptability or versatility
If the covering layer is formed with linear resin ejected from a spaced nozzle to create a linear structure, then the structure can be manufactured with various functions, but the bonding strength between covering layer and base layer decreases
Solution Approach 1:
The patent applies the nesting principle by forming the linear resin structure directly onto the base layer, where the linear resin embeds into and integrates with the base layer surface. This nested configuration creates a strong mechanical interlocking between the covering layer and base layer, preventing peeling while maintaining the ability to manufacture structures with various functions through material selection and design.
3Ease of operation
If the linear resin thickness is increased in certain regions to improve cushioning, then the usability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by varying only the thickness parameter of the linear resin in different regions while keeping other parameters (arrangement interval, nozzle moving path, material composition) constant. This selective parameter modification achieves different cushioning performances in different regions without significantly increasing manufacturing complexity, as the same nozzle and forming process are used throughout.
