Segmented Chassis Assembly for Large LCDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size of liquid crystal displays leads to higher material and distribution costs, as well as increased costs and space requirements for assembly equipment and labor, due to the need for large-sized chassis members in large-sized displays.
Innovation Solution
An apparatus for automatically assembling separated type chassis members to a board and backlight unit, using a supply unit to position the chassis members and a screw coupling unit to secure them, reducing the need for manual labor and minimizing assembly errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large-sized chassis members are used in large-sized liquid crystal displays, then the display size and definition can be increased, but material cost and distribution cost increase
Solution Approach 1:
The chassis is divided into multiple separate chassis members instead of using a single large-sized chassis. This segmentation allows each member to be manufactured independently at smaller sizes, reducing material costs and distribution expenses while still providing the necessary structural support for large-sized displays
2Adaptability or versatility
If large-sized chassis members are used in large-sized liquid crystal displays, then the display size and definition can be increased, but distribution cost increases
Solution Approach 1:
By segmenting the chassis into multiple smaller members, the distribution burden is reduced. Smaller individual components are easier and less expensive to transport compared to a single large chassis, thereby reducing distribution costs while maintaining the capability to assemble large-sized displays
3Adaptability or versatility
If large-sized chassis members are used, then assembly equipment size and occupying space increase
Solution Approach 1:
The assembly equipment can handle smaller chassis members individually, requiring less space for the assembly machinery and workspace. The segmented approach allows for more compact assembly equipment compared to what would be needed to manipulate a single large-sized chassis
Solution Approach 2:
Multiple smaller chassis members are assembled together to form the complete chassis structure for large-sized displays. This combining process occurs at the assembly stage rather than requiring large-sized components throughout the entire manufacturing and handling process
4Adaptability or versatility
If large-sized chassis members are used, then the number of assembly workers required increases
Solution Approach 1:
The chassis is segmented into multiple members that can be handled and assembled more easily. This segmentation makes the assembly process more manageable and can be performed with fewer workers compared to assembling a single large-sized chassis, improving productivity

AI summary
An apparatus for assembling a liquid crystal display is disclosed. The assembly apparatus includes a supply unit that supplies a board and backlight assembly including a backlight unit and a liquid crystal display panel received on the backlight unit at a predetermined assembly location, an assembly unit that in turn draws separated type chassis members from a cartridge, into which the separated type chassis members are loaded, and receives the separated type chassis members at edges of the board and backlight assembly supplied at the predetermined assembly location, and a screw coupling unit that screw-couples the separated type chassis members received at the edges of the board and backlight assembly.
