Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing shoe members using electromagnetic wave irradiation struggle to uniformly adjust the intensity of electromagnetic waves for shoe members made of different materials, leading to undesirable effects in some cases and the need for differentiated wave intensities.
Innovation Solution
A method involving a collective body with distinct portions made of different materials, where electromagnetic wave irradiation is partly shielded using a shielding member to reduce the wave intensity on specific areas, and a molding die with a transmissive member and a shielding member to control electromagnetic wave transmissivity and shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If electromagnetic wave is uniformly irradiated to all shoe members, then heating efficiency is improved, but materials with lower dielectric loss coefficients are insufficiently heated while materials with higher coefficients may be overheated
Solution Approach 1:
The patent applies local quality by differentiating electromagnetic wave irradiation intensity for different regions containing different materials. Shielding members are strategically placed to reduce wave intensity for materials with lower dielectric loss coefficients, while allowing full intensity for materials with higher coefficients, thereby achieving appropriate heating for each material type
Solution Approach 2:
The patent segments the irradiation space into multiple zones using shielding members, creating distinct regions with different electromagnetic wave intensities. This segmentation allows independent control of heating conditions for different material portions within the same collective body
2Reliability
If shielding members are added to control electromagnetic wave intensity for different materials, then material compatibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the shielding function with the molding die structure itself, integrating shielding members into the die body or positioning them within the collective body. This integration reduces the need for separate shielding components and simplifies the overall system while maintaining the ability to control electromagnetic wave intensity

Function Achieved in This Case
This approach allows for the effective adjustment of electromagnetic wave intensity for each material, minimizing adverse effects and achieving precise bonding of shoe members with different materials, enhancing the production process.
Implementation Method 1
partly shielding the electromagnetic wave irradiated toward the second member by a shielding member capable of shielding electromagnetic wave
Implementation Method 2
the resin composition is heated by the electromagnetic wave irradiation, thereby causing the first member and the second member to be bonded to each other by the heated resin composition
