Replaceable Backlight Light Control Circuit with Securing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight module light systems in LCD panels are difficult to replace and maintain, leading to reduced lifespan as damaged components cannot be easily disassembled, resulting in the entire monitor becoming unusable.
Innovation Solution
A replaceable light apparatus with a light control circuit, securing device, and conducting wires, where the light control circuit is restricted by the securing device to prevent movement in specific directions, allowing for stable assembly and easy disassembly, featuring a guiding structure and fastening mechanism to securely attach to the back plate and frame body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lamp tube is directly plugged into the back plate with rubber caps, then the light system is securely fastened, but the lamp tube cannot be easily replaced when broken
Solution Approach 1:
The light system is divided into separable modules: the lamp tube assembly with rubber caps can be independently removed from the back plate through the dedicated slot, allowing replacement without damaging other components. The back plate structure is segmented to include a specific opening that accommodates the lamp tube assembly for easy insertion and removal.
Solution Approach 2:
The lamp tube assembly is extracted as a separate removable component from the back plate system. The rubber caps with conducting wires extending outward allow the lamp tube to be pulled out through the slot in the back plate, separating the replaceable lamp tube from the permanent back plate structure.
2Device complexity
If the light system is plugged into the internal space of the back plate, then the structure is compact, but the light system cannot be disassembled for maintenance
Solution Approach 1:
The back plate is designed with a dedicated slot that separates the light system insertion path from the main structural body. This segmentation allows the light system to be inserted compactly into the internal space while providing a clear removal path through the slot for maintenance purposes.
Solution Approach 2:
The slot in the back plate acts as an intermediary structure that facilitates both compact insertion and easy removal of the light system. The conducting wires extending through the rubber caps serve as intermediaries that allow electrical connection while enabling the light system to be pulled out for maintenance.
3Reliability
If the lamp tube is secured to the back plate, then the light system is stable, but the entire monitor becomes unusable when components are damaged
Solution Approach 1:
The light system is segmented into a removable lamp tube assembly and a permanent back plate structure. When the lamp tube breaks or conducting wires are damaged, only the lamp tube assembly needs to be removed through the slot and replaced, while the back plate and other components remain intact and reusable.
Solution Approach 2:
The design allows selective discarding and replacement of only the damaged lamp tube assembly while recovering and retaining the functional back plate, frame, and other components. The slot structure enables the damaged lamp tube to be removed and a new one installed without wasting the entire light system or monitor.
