Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing backlight modules with quantum tubes are prone to contact with high-temperature strip lights, leading to reduced luminous efficiency and color gamut due to the brittleness of quantum tubes and their proximity to the light source.
Innovation Solution
A backlight module design that incorporates a buckle mechanism to securely fix the quantum tube on a circuit board, maintaining an interval between the quantum tube and the strip light, preventing direct heat contact and ensuring efficient light transmission through the quantum tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the quantum tube is placed adjacent to the strip light to enable light emission, then the backlight module can be assembled, but the quantum tube contacts with the high-temperature strip light causing reduced luminous efficiency and color gamut
Solution Approach 1:
A buckle is introduced as an intermediary component between the quantum tube and the circuit board. The buckle includes a receiving cavity that holds the quantum tube, and a limiting component that prevents the quantum tube from contacting the strip light directly, thus mediating the spatial relationship and preventing harmful thermal contact.
Solution Approach 2:
The buckle extends in multiple dimensions relative to the circuit board, with a receiving cavity that positions the quantum tube at a specific height and lateral position. This multi-dimensional positioning ensures the quantum tube is elevated and laterally constrained, preventing contact with the strip light while maintaining proper optical alignment.
2Volume of moving object
If the quantum tube is placed close to the strip light for compact design, then the device size is reduced, but the brittleness of quantum tube causes it to break easily under thermal stress
Solution Approach 1:
The buckle's receiving cavity is designed with dimensions that provide a clearance between the quantum tube and the strip light. This pre-established spatial buffer protects the brittle quantum tube from thermal stress and mechanical contact before any damage can occur, effectively cushioning against potential failures.
3Device complexity
If the quantum tube is fixed directly to the circuit board, then the assembly is simple, but the quantum tube cannot be isolated from heat affecting color gamut
Solution Approach 1:
The buckle serves as a thermal isolation intermediary between the quantum tube and the heat-generating strip light. By positioning the quantum tube within the buckle's receiving cavity and using the buckle's structure to maintain separation, thermal contact is prevented while maintaining a relatively simple overall assembly process.
