Solution Overview
Problem
The existing methods for fixing a light bar to a heat dissipation mechanism using screws result in loose connections and non-uniform heat dissipation, leading to inconsistent light emission and potential premature failure due to local overheating.
Innovation Solution
A light bar fixing device utilizing a helical spring with a pitch matching the threaded hole of the heat dissipation mechanism, featuring a stop end with a larger outer diameter and a tapered columnar body, ensures secure connection by compressing and engaging tightly with the threaded hole, reducing clearance and maintaining uniform heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the light bar to the heat dissipation mechanism, then the light bar can be connected to the heat dissipation mechanism, but the connection becomes loose during use and clearance appears between the light bar and heat dissipation mechanism
Solution Approach 1:
The patent replaces static screw connections with a dynamic spring-based connection system. The elastic component continuously applies pushing force to maintain contact between the light bar and heat dissipation mechanism, adapting to any dimensional variations or settling that occurs during use, thereby preventing loosening and maintaining consistent thermal contact.
Solution Approach 2:
The patent changes the connection mechanism from rigid (screws) to elastic (spring), utilizing the elastic deformation parameter of the spring material. The spring's ability to deform and recover provides continuous contact pressure, ensuring stable connection and consistent thermal coupling between the light bar and heat dissipation mechanism throughout operation.
2Reliability
If screws are used to fix the light bar, then the light bar can be mounted, but non-uniform heat dissipation occurs due to clearance, causing inconsistent light spectrum and potential premature failure
Solution Approach 1:
The elastic component provides dynamic, continuous contact pressure that ensures uniform thermal coupling between the light bar and heat dissipation mechanism. This eliminates clearance-induced non-uniform heat dissipation, maintaining consistent temperature distribution across the light bar surface and preventing localized overheating that would reduce service life.
Solution Approach 2:
The elastic component acts as an intermediary element between the light bar and heat dissipation mechanism, ensuring optimal thermal contact. It mediates the thermal transfer process by maintaining consistent pressure and contact area, thereby achieving uniform heat dissipation and consistent light emission spectrum throughout the light bar's operational life.

AI summary
A light bar fixing device comprises a light bar defining a through-hole and a heat dissipation mechanism defining a threaded hole corresponding to the through-hole. The light bar fixing device further comprises a helical spring having a pitch identical to that of the threaded hole. A columnar body of the helical spring is adapted to be threaded into the threaded hole, and an outer diameter of a stop end of the helical spring is greater than that of the columnar body. By threading the helical spring into the threaded hole, the light bar can be securely connected to the heat dissipation mechanism with a clearance therebetween being reduced. Also, the light bar can dissipate heat evenly via the heat dissipation mechanism to allow a uniform temperature distribution in the light bar, thus resulting in a desirable light emitting effect and a prolonged service life of the light bar.
