Pet Light Guide Bar Heat Dissipation and Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet lasso tools, such as chest harnesses and collars, lack light-emitting devices, making it difficult to detect pets in dark conditions, and existing LED light strips generate heat, causing discomfort to pets.
Innovation Solution
A pet light-emitting safety device using a light guide bar with two light-emitting diodes that emit light to the ends of the guide bar, controlled by a light source controller, providing various lighting modes and low heat generation, which can be easily integrated into pet harnesses and collars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED light strips are used as light-emitting devices on pet lasso tools, then the pet position can be detected in dark conditions, but the light-emitting devices generate a lot of heat which makes pets feel uncomfortable
Solution Approach 1:
The patent introduces a light guide bar as an intermediary component between the LED light source and the pet's body. The LED emits light that is guided and distributed along the light guide bar, which has a larger surface area for heat dissipation. This mediator structure allows the light-emitting function to be achieved while the heat is dispersed over a larger area, reducing the temperature felt by the pet.
Solution Approach 2:
The light guide bar extends the light-emitting function from a point source (LED) to a linear distribution along the bar. This dimensional extension allows heat to be distributed along the length of the bar rather than concentrated at one point, effectively reducing the temperature at any single location where the pet contacts the harness.
2Device complexity
If conventional pet lasso tools without light-emitting devices are used, then the device complexity is low, but the pet position cannot be easily detected in dark conditions
Solution Approach 1:
The light guide bar serves multiple functions: it guides and distributes light along its length, provides a structural mounting element for the LED, and acts as a heat dissipation pathway. This multi-functionality allows the visibility feature to be added without proportionally increasing device complexity, as the light guide bar integrates several roles into a single component.
3Illumination intensity
If LED light strips are used to provide illumination, then the lighting effect is achieved, but the heat generated causes discomfort to the pet
Solution Approach 1:
The light guide bar acts as a mediator that separates the heat-generating LED from the pet's body. It transmits the light function while dissipating heat over its extended structure, reducing the harmful thermal effect on the pet.
Solution Approach 2:
The light guide bar can be implemented as a flexible, thin structure that conforms to the pet's body contours. This flexible design allows for better heat distribution across a larger surface area while maintaining close contact with the pet for effective heat dissipation without causing discomfort.

AI summary
A pet light-emitting safety device includes a light guide bar and a light source controller controlling light transmitting to the light guide bar. The light guide bar includes a light-emitting body and fixing portions connected to the light-emitting body. The fixing portions define end surfaces configured to input the light. The light source controller includes a box body, a main control board accommodated in the box body, and light sources connected to the main control board. Sides of the box body defines channels fixing the fixing portions. The fixing portions are separately inserted into a corresponding channel. Each of the light sources is arranged on one end of each of the fixing portions away from the corresponding channel. Light-emitting surfaces of the light sources face the end surfaces of the fixing portions. A pet chest and back harness and a pet collar include the pet light-emitting safety device.
