Heater Element Mounting Structure with Temporary Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heater element mounting structures are unstable, leading to a high risk of the heater element falling out of the board during assembly, due to the lack of secure fixation of the lead terminal within the guide hole, especially when the radiator plate is mounted in a reversed configuration.
Innovation Solution
A mounting structure that includes a supporting member temporarily fixed to the board, providing a predetermined play between the supporting member and the board, allowing the heater element to be easily positioned and secured, with a snap-fit structure and elastic legs to ensure stable fixation and alignment with the cooling member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the heater element is mounted on the board using a guide hole and fixing screws without a supporting member, then the structure is simpler, but the heater element becomes unstable and may fall out during assembly
Solution Approach 1:
A supporting member is introduced as an intermediary component between the heater element and the board. This supporting member includes a supporting hole that receives the lead terminal and provides stable support during assembly, preventing the heater element from falling out while maintaining relative simplicity of the overall structure.
Solution Approach 2:
The supporting member is temporarily fixed to the board before mounting the heater element. This preliminary action creates a stable foundation that guides and secures the heater element in the correct position, ensuring stability during the assembly process before the final fixing screws are applied.
2Reliability
If the heater element is temporarily fixed with a supporting member, then the stability during assembly is improved, but the device complexity increases
Solution Approach 1:
The supporting member serves as a temporary intermediary that facilitates stable assembly. After the heater element is securely mounted using fixing screws, the supporting member can be removed, having fulfilled its purpose of preventing instability during the critical assembly phase without becoming a permanent part of the final structure.
Solution Approach 2:
The supporting member is designed as a temporary, disposable component that is used only during the assembly process. It can be a simple, low-cost part that is discarded after serving its function of preventing the heater element from falling out, thereby minimizing the impact on overall device complexity and cost.
3Productivity
If the lead terminal is inserted into the guide hole without temporary fixation, then the assembly process is faster, but the lead terminal may fall out due to gravity when the radiator plate is mounted in reverse
Solution Approach 1:
The supporting member is temporarily fixed to the board before the heater element is installed. This preliminary action ensures that when the lead terminal is inserted into the supporting hole, it is immediately supported and cannot fall out due to gravity, even when the radiator plate is mounted in reverse orientation.
Solution Approach 2:
The supporting member acts as an intermediary structure that provides a stable receiving hole for the lead terminal. This intermediary structure prevents the lead terminal from falling out during assembly operations, allowing for faster assembly without compromising retention reliability.

AI summary
A mounting structure for a heater element includes a heater element having a surface to be cooled, a board on which the heater element is mounted, a cooling member that cools the surface to be cooled of the heater element mounted on the board, and a supporting member temporarily fixed to the board, the supporting member temporarily fixing the heater element.
