Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional assembly methods are used to attach light emitting diode modules and light guide plates separately, then the assembly process becomes complex and time-consuming, but the structural stability and optical alignment are compromised
Solution Approach 1:
The patent combines the light guide plate and light emitting diode module into a single integrated assembly unit. The light guide plate is positioned within a housing that also accommodates the LED module, allowing both components to be assembled and positioned simultaneously using a single supporter structure, thereby simplifying the assembly process while maintaining proper optical alignment.
Solution Approach 2:
The supporter structure serves multiple functions: it holds the light guide plate, positions the light emitting diode module, and ensures proper alignment between the two components. This multi-functional design eliminates the need for separate assembly steps and fixtures, reducing assembly complexity while guaranteeing optical performance.
2Productivity
If multiple separate components and assembly steps are used, then the assembly time and cost increase, but the positioning precision of light sources is reduced
Solution Approach 1:
The light guide plate and LED module are merged into a single assembly unit that is installed in one step. The housing structure integrates both components, eliminating multiple assembly operations and reducing assembly time while ensuring precise positioning through the unified structure.
Solution Approach 2:
The light guide plate is pre-positioned within the housing structure before the LED module is installed. This preliminary positioning ensures that when the LED module is subsequently attached, the alignment between the light sources and light guide plate is already optimized, maintaining manufacturing precision while streamlining the assembly process.
3Device complexity
If traditional holder structures are used for light emitting diode modules, then the device complexity and weight increase, but the assembly simplicity is reduced
Solution Approach 1:
The housing structure that holds the light guide plate is designed to also accommodate and position the LED module without requiring separate holders or brackets. This merging of functions reduces structural complexity and eliminates additional components, making the assembly process simpler while maintaining device stability.
Solution Approach 2:
The housing structure serves as both the mounting frame for the light guide plate and the support structure for the LED module. This universal structure eliminates the need for additional holders, reducing overall device complexity while simplifying assembly operations through a single integrated component.

Data Source
AI summary
The present disclosure is a backlight module including a light guide plate, a supporter, and a light source module. The light guide plate has a light incident side. The supporter has a bottom plate, a sidewall, and a top plate corresponding to the bottom plate. The bottom plate extends from a first end of the sidewall toward the light guide plate, and the top plate extends along a second end of the sidewall toward the light guide plate. The length of the sidewall is longer than the length of the top plate, such that the top plate corresponding to the sidewall forms at least one breach to expose the second end of the sidewall. The bottom plate, the top plate, and the sidewall together form an accommodating space, and the light incident side of the light guide plate is disposed between the top plate and the bottom plate. The light source module is disposed in the accommodating space and partially exposed through the at least one breach. The light source module has at least one light emitting unit and a printed circuit board. The light emitting unit is disposed on the printed circuit board, such that an emitting surface of the light emitting unit can face the light incident side of the light guide plate.
