Multi-Face Stand Fastening for Large Display Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen plasma display apparatuses experience instability and safety concerns due to their weight, as existing stand-attaching structures fail to securely fasten the devices, leading to wobbling and increased manufacturing costs when reinforcing members are added.
Innovation Solution
A stand-attaching structure that uses a hollow, bar-shaped main frame extending vertically and fixed to the upper and lower portions of the outer frame, with the leg portion of the stand inserted into the main frame and secured at different heights, providing additional stability and safety without increasing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-face fastening structure is used to attach the main frame to the stand, then the device complexity is reduced, but the stability and quake resistance deteriorate
Solution Approach 1:
The patent transitions from single-face fastening to multi-face fastening, attaching the main frame to the stand at multiple locations including front, rear, and side faces. This dimensional expansion of attachment points significantly enhances stability without adding complex reinforcing members, directly resolving the contradiction between structural simplicity and stability.
Solution Approach 2:
The hollow bar-shaped main frame is inserted into the stand's support structure, creating a nested configuration where the main frame fits within the stand's internal cavity. This nesting approach provides inherent structural support and stability while maintaining a simple overall design, eliminating the need for additional reinforcing members.
2Reliability
If reinforcing members are added to enhance quake resistance, then the reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The main frame serves multiple functions simultaneously: it supports the display module, provides structural rigidity, and acts as the attachment interface to the stand through multi-face fastening. This multi-functionality eliminates the need for separate reinforcing members, achieving high reliability without increasing manufacturing complexity or cost.
Solution Approach 2:
The patent combines the support function and the fastening function into a single integrated main frame structure. The hollow bar-shaped main frame both supports the display module and provides attachment surfaces for the stand, merging multiple structural roles into one component and avoiding the need for additional reinforcing elements.
3Area of stationary object
If the screen size is increased to provide larger display area, then the visual comfort is improved, but the weight increases causing stability issues
Solution Approach 1:
The patent addresses the stability issue of large-screen displays by transitioning from single-point or single-face support to multi-dimensional multi-face fastening. The main frame is attached to the stand at multiple locations (front, rear, and side faces), distributing the weight load across multiple attachment points and enhancing stability despite the increased weight of large-screen displays.
Solution Approach 2:
The main frame utilizes a hollow bar-shaped structure that provides high strength-to-weight ratio, combining structural rigidity with weight efficiency. This composite-like structure supports large-screen displays effectively while maintaining overall apparatus stability through its inherent structural properties and multi-face fastening configuration.

AI summary
A large-screen image display apparatus includes a stand for supporting the display module, which has a leg portion. The leg portion of the stand is inserted into the main frame. The leg portion and the main frame are fastened together at a first screw hole formed through the leg portion. In addition, the leg portion and a fixing part of the outer frame are fastened together at a second screw hole formed through the leg portion. The first screw hole and the second screw hole are formed on different faces of the leg portion and at different heights. This can provide a large-screen image display apparatus with a less-wobble, high-safety, high-reliability, and low-cost stand-attaching structure.
