Solution Overview
Problem
Existing manufacturing methods for warming tools with perfumes face issues of contamination, inefficient production due to perfume adherence, and compromised heat generating performance or user discomfort, particularly when switching between perfume-scented and non-scented models or different perfume types.
Innovation Solution
A warming tool design with specific arrangements of adhesive and perfume regions, using air-permeable and non-air-permeable sheets to separate adhesive and perfume areas, ensuring effective joining, reducing contamination, and maintaining heat generating performance while enhancing user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If perfume is added to the warming tool during manufacturing, then the warming tool gives off pleasant scent during use, but the perfume adheres to the manufacturing apparatus and contaminates it
Solution Approach 1:
The patent segments the warming tool structure into distinct regions: a first region containing the heat generating element and a second region containing the perfume, with these regions separated by a partition wall. This segmentation prevents perfume from adhering to the manufacturing apparatus during production while still allowing the perfume to function properly in the finished product.
Solution Approach 2:
The partition wall acts as an intermediary barrier between the perfume and the manufacturing apparatus. It allows the perfume to be contained within the warming tool structure during manufacturing, preventing contamination of the apparatus while maintaining the perfume's functionality after production.
2Ease of manufacture
If perfume is added to the warming tool, then the warming tool provides pleasant fragrance, but the heat generating performance may be compromised
Solution Approach 1:
The warming tool is divided into functionally independent regions: the first region for heat generation and the second region for perfume storage. This spatial segmentation ensures that the perfume does not interfere with the heat generating element's performance while still allowing the perfume to volatilize and provide fragrance during use.
Solution Approach 2:
Different regions of the warming tool are assigned different functional properties: the first region is optimized for heat generation with appropriate material properties, while the second region is designed for perfume storage and volatilization. This local differentiation ensures that each component performs its function optimally without compromising the other.
3Strength
If adhesive is applied to join components, then the warming tool structure is secured, but the adhesive may contaminate the perfume area
Solution Approach 1:
The partition wall creates distinct zones that separate the adhesive application areas from the perfume storage area. Adhesive can be applied to join components in the first region without contaminating the second region where the perfume is stored, as the partition wall acts as a physical barrier.
Solution Approach 2:
The partition wall serves as an intermediary structure that prevents adhesive from migrating into the perfume storage region. It allows the adhesive to perform its joining function in the first region while blocking any potential contamination of the perfume in the second region.

AI summary
The present invention relates to a warming tool (1) in which a heat generating element (3) is held between a topsheet (5) that faces a heating target and a backsheet (6) that is located on a side away from the heating target, and a method for manufacturing the same. The heat generating element (3) has a first sheet (3f) arranged opposing the topsheet (5), a second sheet (3g) arranged opposing the backsheet (6), and a heat generating portion (3a) sandwiched between the first sheet (3f) and the second sheet (3g). In the warming tool (1), a perfume (8) and an adhesive (7) are arranged between the second sheet (3g) and the backsheet (6), and a region in which the adhesive (7) is arranged and a region in which the perfume (8) is not arranged overlap each other in a plan view. In the manufacturing method, the perfume is added to a surface of the second sheet (3g) that is planned to oppose the backsheet (6), or to a surface of the backsheet (6) that is planned to oppose the heat generating element (3), and the heat generating element (3) is held such that the backsheet (6) and the second sheet (3g) oppose each other.
