Heater Base With Layered Heating Bodies and Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heaters with multiple heating bodies, densely disposed terminals often interfere with the inside heating body, leading to temperature decreases on the center side of the base due to insufficient spacing and potential electrical insulation issues.
Innovation Solution
The design includes a disk-shaped base with inside and outside heating bodies spaced in the thickness direction, where terminals are concentrically disposed to avoid interference, with the second terminal connected to the second outside heating body positioned farther from the inside heating body, allowing for increased spacing and preventing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals are densely disposed on the center side of the base to connect heating bodies, then the electrical connection is improved, but the terminals interfere with the inside heating body causing temperature decrease
Solution Approach 1:
The patent resolves the spatial conflict by transitioning from two-dimensional planar arrangement to three-dimensional layered arrangement. Terminals are disposed at different heights (thickness direction) relative to heating bodies, allowing dense electrical connections without planar interference. Specifically, terminals connected to outside heating bodies are positioned at a second height different from the first height of inside heating bodies, enabling both reliable electrical connection and temperature uniformity.
2Device complexity
If the second terminal is connected to the first outside heating body closer to the inside heating body, then the connection is simpler, but the terminal interferes with the inside heating body
Solution Approach 1:
The patent eliminates terminal interference by utilizing the thickness direction (vertical dimension) rather than increasing horizontal separation. The second terminal connected to the second outside heating body is positioned at a second height different from the first height of inside heating bodies, providing sufficient spatial clearance without complicating the connection structure.
3Use of energy by moving object
If the inside heating body is positioned closer to the first surface for optimal heating, then the heating efficiency is improved, but terminals may contact the heating body due to insufficient spacing
Solution Approach 1:
The patent ensures electrical insulation by implementing vertical layering where terminals and heating bodies occupy different heights in the thickness direction. Inside heating bodies are positioned at a first height while terminals are at a second height, providing inherent electrical insulation without requiring increased horizontal spacing, thus maintaining heating efficiency.

AI summary
A heater includes a base, a plurality of heating bodies, a plurality of terminals, and a cylindrical. The base has a first surface on which a heating target is placed, and a second surface opposite to the first surface. The plurality of heating bodies include an inside heating body disposed in a region including a center of the base, and a plurality of outside heating bodies disposed outside of the inside heating body to be concentric with the base. The inside heating body and the plurality of outside heating bodies are disposed to be spaced from each other in a thickness direction of the base. The inside heating body is disposed at a first layer located closest to the first surface in the thickness direction of the base. The plurality of outside heating bodies include a first outside heating body, and a second outside heating body.
