Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing backframes for liquid crystal displays are rigid and volumetrically heavy, leading to inefficient transportation and storage due to their large dimensions, resulting in high costs for container usage.
Innovation Solution
A collapsible backframe design featuring interlinked primary struts and secondary bars with pinshafts and stoppers, allowing the backframe to be compacted during non-use and extended when needed, reducing overall volume and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the backframe is integrally formed with a planar configuration to provide structural support, then the strength and stability are improved, but the volumetric weight and transportation efficiency deteriorate
Solution Approach 1:
The backframe is divided into multiple independent struts (first struts and second struts) that can be separated and reconfigured. Each strut maintains structural integrity while the segmented design allows compact folding arrangements, reducing volumetric weight during transportation while preserving strength during use
Solution Approach 2:
The backframe transitions from a static planar configuration to a dynamic reconfigurable structure. The struts are designed to be movable relative to each other through folding mechanisms, enabling the frame to adapt between an extended operational state (providing structural support) and a compact storage state (reducing volume)
2Area of stationary object
If the backframe is designed with large dimensions to match the liquid crystal display panel, then the support coverage and stability are improved, but the transportation and storage efficiency deteriorate
Solution Approach 1:
The large-area backframe is segmented into multiple struts that can be folded together, allowing the structure to maintain full coverage area during operation while compacting to a fraction of that volume during transportation and storage
Solution Approach 2:
The struts are designed to nest within each other when folded, with smaller struts fitting inside larger ones, maximizing space utilization during storage and transportation while maintaining full structural coverage when deployed

AI summary
The present invention discloses a liquid crystal display and a backframe for a liquid crystal display. The backframe is configured by interlinked linkages such that the backframe can be locked in a fully extended position in use, or be collapsible when not in use in a way that the overall dimension of the collapsible backframe is smaller than the fully extended backframe. The backframe can be switched from a fully extended position under normal use, or a collapsible position under a transportation or storage. The collapsible position occupies less volumetric weight as compared to the fully extended position so as to reduce the volumetric weight when the backframe is in transportation and storage. As a result, the performance of the transportation and storage can be therefore increased, while the cost is reduced.
