Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connecting structures in automobile lamps, such as those using LED luminous chips, suffer from slow heat diffusion due to restricted air circulation, leading to higher temperatures and reduced performance and service life.
Innovation Solution
A threaded connecting member with a radiating function, featuring a radiating passage that runs through its length, allowing for heat exchange between spaces on either side of the connector, enhancing heat diffusion capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional screw connecting structure is used to fix the substrate and radiator, then the structural simplicity is maintained, but the heat diffusion capability is insufficient due to restricted air circulation
Solution Approach 1:
The screw is segmented into multiple functional zones: a threaded rod portion for mechanical fastening, and a radiating portion with radiating fins extending from the surface. This segmentation allows the single screw to simultaneously perform both structural and thermal functions, resolving the contradiction between simplicity and heat diffusion capability
Solution Approach 2:
The invention merges the mechanical fastening function and the heat dissipation function into a single integrated screw component. The radiating fins are directly formed on the screw body, combining what would traditionally require separate fastening hardware and separate thermal management components, thus maintaining structural simplicity while improving heat diffusion
2Temperature
If additional metal radiators are added to improve radiating capabilities, then the heat diffusion is improved, but the device complexity increases
Solution Approach 1:
The screw is designed as a multi-functional component that simultaneously serves as a mechanical fastener and a thermal radiator. The radiating fins on the screw body enable it to perform heat dissipation in addition to its fastening function, eliminating the need for separate dedicated radiator components and thus avoiding increased device complexity
Solution Approach 2:
The screw serves itself by incorporating radiating fins directly on its body. The same component that performs mechanical fastening also performs thermal management, making the system self-sufficient and eliminating the need for additional dedicated radiating components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The threaded connecting member improves heat diffusion by enabling gas exchange through the radiating passage, reducing temperature and extending the service life and performance of connected devices like automobile lamp systems.
Implementation Method 1
the heat firstly is transferred to the substrate 1 and then is convectively dissipated into surrounding air through the radiator 2
Implementation Method 2
the heat produced by the LED luminous chip 3 is transferred to the radiator 2 only through the heat transfer effect of the substrate 1

AI summary
The present invention provides a threaded connecting member and a threaded connecting structure with a radiating function. Since a radiating passage which extends along a length direction of the threaded connecting member is provided on the threaded connecting member and the radiating passage runs through one end of the threaded connecting member to the other end of the threaded connecting member, when the threaded connecting member with the radiating function provided by the present invention is used, the threaded connecting member is provided in a connecting hole in a connector in a penetrating manner, the radiating passage communicates spaces on two sides of the connector, gas in the spaces on the two sides of the connector can perform heat exchange through the radiating passage and thereby the heat diffusion capability of a connected device is improved.
