Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If heat radiation parts are arranged in a distributed manner on the surface, then heat radiation efficiency is improved, but temperature control at contact points becomes difficult
Solution Approach 1:
The patent applies local quality by creating regions with different thermal conductivities in different locations. Low thermal conductive parts are positioned at specific locations surrounding heat radiation parts, while other areas maintain high thermal conductivity. This spatial variation in material properties enables simultaneous heat radiation efficiency and localized temperature control at contact points.
Solution Approach 2:
The low thermal conductive parts act as intermediary elements between the heat radiation parts and the surrounding structure. These intermediaries control heat flow from the heat radiation parts to adjacent areas, preventing excessive temperature buildup at contact points while maintaining effective heat radiation.
2Temperature
If low thermal conductive parts are introduced to reduce heat transfer, then temperature at contact points is reduced, but device complexity increases
Solution Approach 1:
The patent merges the low thermal conductive parts with the existing heat radiation part structure, creating an integrated configuration where low thermal conductive materials are incorporated into or around the heat radiation parts. This integration approach reduces overall device complexity compared to adding separate, independent temperature control systems.
3Length of stationary object
If heating parts are arranged within a thin layer, then apparatus thickness is reduced, but heat generation efficiency may be compromised
Solution Approach 1:
The patent applies parameter changes by optimizing the thickness parameter of the heating parts and their thermal connection to heat radiation parts. By carefully controlling the thickness parameter and thermal conductivity parameters, the patent achieves effective heat generation and transfer within a reduced overall apparatus thickness, maintaining heat generation efficiency while minimizing thickness.

Data Source
AI summary
A radiation heater apparatus has a plurality of heat radiation parts and a plurality of heating parts. A low thermal conductive part is formed between adjacent two of the heat radiation parts. The low thermal conductive part is provided with resin material which mainly forms a substrate part. The low thermal conductive part thermally isolates the heat radiation part by surrounding a periphery of the heat radiation part. As a body contacts with the surface of the apparatus, the thermal energy of specific heat radiation part directly under the body dissipates heat to the body. Furthermore, heat transfer from the periphery of the specific heat radiation part to the specific heat radiation part is reduced by the low thermal conductive part.
