Engineering Contradiction Analysis
1Length of moving object
If conventional installation methods are used, then the structure is simple, but the installation space is insufficient for ultra-thin design
Solution Approach 1:
The fixing part is inserted into insertion holes formed in the back frame, light guide plate, and optical film, nesting the fixing mechanism within the existing component structure. This allows multiple components to be combined in a compact manner, reducing overall thickness while maintaining adequate installation space through efficient space utilization of the insertion holes.
Solution Approach 2:
The fixing part extends from one dimension (engaging the side surface of the light guide plate) into another dimension (inserting through holes in the back frame and optical film). This multi-dimensional engagement approach maximizes the use of available space within the ultra-thin structure, allowing secure fixation without increasing overall thickness.
2Shape
If the thickness is reduced for ultra-thin design, then the appearance is improved, but the space for installing components becomes insufficient
Solution Approach 1:
The fixing part is nested within the insertion holes of the back frame, light guide plate, and optical film, allowing secure component fixation within the limited volume of the ultra-thin structure without compromising the thin appearance.
Solution Approach 2:
The fixing part is divided into multiple segments (engagement portion and insertion portions) that can be distributed across different components (back frame, light guide plate, optical film). This segmentation allows the fixation function to be achieved through multiple small-volume elements rather than a single large component, preserving the ultra-thin appearance.
3Productivity
If more components are integrated into the backlight module, then the assembly is more compact, but the manufacturing complexity increases
Solution Approach 1:
The back frame, light guide plate, and optical film are merged into a single integrated backlight module assembly through the fixing part. This combining approach achieves compactness by reducing the number of separate components and assembly steps, while the standardized fixing mechanism keeps manufacturing complexity manageable.
Solution Approach 2:
The fixing part serves multiple functions: it engages the side surface of the light guide plate, inserts into the back frame, and inserts into the optical film. This multi-functionality allows a single component to achieve compact integration of multiple elements, improving assembly compactness while avoiding the need for multiple specialized fastening components that would increase manufacturing complexity.
