Adjustable Support Frame for Display Device Circuitry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The configuration of flat display devices with signal control and power supply boards moved to the base limits the accommodation space within the support frame, making the length of the support frames non-adjustable, which restricts the functionality of the frame and prevents the accommodation of limiting stoppers.
Innovation Solution
A display device with a support frame assembly comprising an inner rail, an outer rail, and a first stop member, where the outer rail is movably connected to the inner rail, forming an accommodation space for flexible circuitry that connects the display to the base, and a slide assembly allows the outer rail to move within a defined range, preventing damage to the circuitry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If signal control and power supply boards are moved to the base of the support frame, then the display device can be made thinner, but the accommodation space within the support frame is limited and no space is left for disposing limiting stoppers
Solution Approach 1:
The support frame is divided into an inner rail and an outer rail, creating a nested structure. The inner rail is disposed within the outer rail, forming an accommodation space between them. This segmentation allows the support frame to accommodate both the flexible circuitry and the limiting stoppers simultaneously, resolving the space limitation issue while maintaining the thin profile of the display device.
2Weight of stationary object
If signal control and power supply boards are moved to the base of the support frame, then the display device can be made thinner, but the length of the support frame becomes non-adjustable
Solution Approach 1:
The outer rail is configured to be movable relative to the inner rail along the inner rail's length. The movable support frame assembly includes a moving component that allows the outer rail to slide along the inner rail, enabling adjustment of the support frame length. This dynamic configuration provides adaptability for different viewing heights while maintaining the thin display device profile.
3Device complexity
If limiting stoppers are not disposed in the support frame, then the support frame structure is simpler, but the outer rail cannot be restricted to move within a defined range
Solution Approach 1:
The support frame is segmented into inner and outer rails with a limiting stopper disposed between them. The limiting stopper is positioned to extend from the inner rail toward the outer rail, defining the movement range of the outer rail. This segmentation approach protects the flexible circuitry from damage while maintaining a relatively simple overall structure.
Solution Approach 2:
The limiting stopper acts as an intermediary element between the inner rail and the outer rail. It restricts the movement of the outer rail along the inner rail to a predetermined range, preventing the flexible circuitry from being damaged during movement while maintaining structural simplicity.

AI summary
A display device includes a display, a base, a flexible circuitry connecting the display to the base, and a support frame assembly disposed between the display and the base. The support frame assembly includes an inner rail connecting to the base, an outer rail connecting to the display, and a first stop member. The outer rail is movably connected to the inner rail so that the outer rail is disposed at a first position or a second position relative to the base. An accommodation space is formed between the outer rail and the inner rail for accommodating the flexible circuitry. The first stop member is disposed between the inner rail and outer rail and extends from the inner rail and away from the accommodation space for restricting the outer rail to move along the inner rail between the first position and the second position.
