Solution Overview

Problem

Existing three-dimensional modeling equipment for manufacturing structures like shoe insoles faces challenges in simplifying the nozzle's moving path complexity when forming regions with different elasticity, peeling issues between layers, and limited usability due to inadequate pressure distribution data integration and shape retention.

Innovation Solution

The solution involves a structure with first and second elastic regions formed by varying the thickness of linear resin, acquiring pressure distribution data to generate forming data, and using a three-dimensional modeling system with a nozzle that changes thickness and moving path based on this data to improve usability and prevent layer peeling, along with a base layer and covering layer configuration that includes a shape memory material for shape retention.
