Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices have a high material and manufacturing cost for back frames due to their unitary design, which also lack a cushioning mechanism to protect the light homogenization mechanism from violent shakes.
Innovation Solution
A back frame comprising multiple primary assembling pieces with elastic members on the upper surface to support the light homogenization mechanism, allowing for shock absorption and reduced material usage through modular design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unitary back frame is used, then the structure is simple, but the material cost and manufacturing cost are high
Solution Approach 1:
The back frame is divided into multiple separate assembling pieces (first back frame piece, second back frame piece, third back frame piece, fourth back frame piece) that can be manufactured independently using smaller, less expensive molds and then assembled together. This segmentation allows each piece to be produced with simpler equipment while achieving the same overall structural function.
2Device complexity
If a unitary back frame is used, then the structure is simple, but the material consumption is high
Solution Approach 1:
By dividing the back frame into separate pieces, each component can be optimized for its specific function and sized appropriately, avoiding the material waste that occurs in unitary designs where material must be provided for the entire frame structure including areas not needed for light homogenization mechanism support.
3Device complexity
If no cushioning mechanism is provided, then the structure is simple, but the light homogenization mechanism is easily damaged by violent shakes
Solution Approach 1:
The elastic members are pre-installed on the back frame pieces to provide cushioning protection for the light homogenization mechanism before any violent shakes occur. This beforehand cushioning allows the system to absorb shock and vibration, protecting the light homogenization mechanism from damage while maintaining overall structural simplicity.
4Reliability
If elastic members are added to protect the light homogenization mechanism, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The elastic members are integrated with the back frame pieces during assembly, merging the cushioning function with the structural support function. This combining approach allows the back frame to simultaneously provide structural integrity and shock protection without requiring separate, additional components that would increase overall device complexity.
