Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating shawls fail to uniformly distribute heat, resulting in uneven heating, low surface temperature, and inadequate hot compress physical therapy effects.
Innovation Solution
A heating shawl design featuring a shawl body with integrated heat conducting lines and a counterweight structure, including a hollow connecting part and counterweight, ensures uniform heat distribution and improved heating efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating element is arranged in the shawl body, then the interior can be heated, but the heat transferred to the surface is insufficient, resulting in low temperature and uneven heating
Solution Approach 1:
The patent introduces heat conducting lines as an intermediary substance between the heating element and the shawl surface. These lines act as thermal conduits that efficiently transport heat from the heating element to the outer surface, solving the problem of insufficient heat transfer and low surface temperature while maintaining energy efficiency.
Solution Approach 2:
The heating system is segmented into distinct functional components: the heating element generates heat, the heat conducting lines transport heat, and the shawl surface distributes heat. This segmentation allows each component to be optimized for its specific function, improving overall heat transfer efficiency and surface temperature uniformity.
2Temperature
If heat is generated in the interior, then heating function is achieved, but the heat distribution across the shawl is uneven
Solution Approach 1:
The patent transitions from point-source heating (heating element) to line-source heating (heat conducting lines distributed across the shawl). By extending the heat conduction path from a single point to multiple lines covering the shawl surface, the system achieves uniform two-dimensional heat distribution without significantly increasing structural complexity.
3Ease of operation
If the shawl is made of soft material, then comfort is improved, but heat conduction capability is reduced
Solution Approach 1:
The shawl employs composite material construction, combining soft, skin-friendly fabric for comfort with heat conducting lines (likely made of materials with high thermal conductivity) for efficient heat transfer. This composite structure allows the shawl to maintain both comfort and effective heat conduction capability simultaneously.
