Detachable Base for LCD TV with Arc-Shaped Pillar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LCD TV bases face issues with structural strength due to concentrated bending forces, electromagnetic interference (EMI), and increased packaging costs due to the complex assembly and large 'T' shape of the base and body, making it difficult for consumers to detach and assemble, and requiring larger packaging volumes.
Innovation Solution
A detachable base comprising a base-plate with a positioning block and a supporting pillar, connected via a connecting assembly that allows easy assembly and disassembly, providing structural strength while reducing packaging volume and EMI through the use of insulating materials and a stable supporting structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the base-plate and body of LCD TV are assembled to form a reverse 'T' shape, then the structural support is improved, but the packaging volume increases and costs increase
Solution Approach 1:
The base assembly is divided into separable components: the base-plate and the connecting assembly can be detached from each other. This allows them to be stacked efficiently in packaging boxes, reducing packaging volume while maintaining structural support when assembled
Solution Approach 2:
The base structure transitions from a fixed permanent assembly to a dynamic detachable design. The connecting assembly can be easily attached and detached, allowing the base-plate to be separated for compact packaging and reassembled for structural support during use
2Strength
If the connecting base is made of metal to ensure strength, then the structural support is improved, but electromagnetic interference problems occur frequently
Solution Approach 1:
The connecting assembly uses composite construction combining metal components (for strength in the bearer and connecting base) with insulating materials (such as plastic or rubber coatings and insulating washers). This composite structure maintains structural support capability while preventing electromagnetic interference through the insulating layers
3Device complexity
If the fastener length is limited to maintain compact design, then the device complexity is reduced, but the bending force becomes highly concentrated causing critical conditions
Solution Approach 1:
The bearer is designed with a curved arc-shaped structure instead of a straight configuration. This curvature distributes the bending force along the arc, reducing stress concentration on the fastener while maintaining a compact design. The arc shape allows the fastener to engage more effectively with the connecting base, improving reliability without increasing fastener length

AI summary
A detachable base, for supporting an object as a flat-panel display comprises a base-plate, a supporting pillar, and a connecting assembly. The base-plate has a positioning block disposed on an upper surface thereof. The positioning block has a fillister. The supporting pillar has an upper end and a lower end, the lower end of the supporting pillar is received in the fillister of the positioning block. The connecting assembly is connected with the object and has an accommodating space for receiving the supporting pillar and the positioning block when the connecting assembly is connected with the base-plate.
