Slim Display Lift Structure Using Nested Rail and Constant-Force Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevatable supporting devices for displays are too bulky due to their wide design, which inefficiently uses space and results in a visually unappealing, bulky appearance.
Innovation Solution
The design incorporates a single lateral rail module and frame components within an inner space defined by a sliding element, utilizing a U-shaped configuration with constant force springs and friction structures to allow the rail module to slide efficiently, reducing the overall width and volume of the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the main board is disposed outside the sliding device, then the sliding device can have a simpler structure, but the overall width of the elevatable structure becomes too large and bulky
Solution Approach 1:
The patent applies nesting by placing the first rail module inside the inner space defined by the sliding element, and positioning the main board within the space created by this nested arrangement. This allows multiple components to occupy overlapping or nested spatial volumes, reducing the overall width of the elevatable structure while maintaining functional independence of each component
Solution Approach 2:
The patent repositions components from a lateral arrangement (outside the sliding device) to a depth-oriented arrangement (inside the inner space). By utilizing the depth dimension (thickness direction) rather than only the width dimension, the design achieves compactness in the width direction while accommodating all necessary components through three-dimensional spatial optimization
2Ease of manufacture
If conventional elevatable structures are designed with wider spacing for component placement, then components can be easily assembled and maintained, but the device appears visually bulky and uses space inefficiently
Solution Approach 1:
The sliding element's inner space is utilized to nest the rail module and main board, creating a compact configuration that reduces overall device volume. The U-shaped structure with lateral flanges defines this inner space, allowing components to be positioned within rather than around the sliding element, thereby achieving space efficiency without compromising assembly feasibility

AI summary
An elevatable supporting device for holding a display module which is defined with a normal direction is provided. The elevatable supporting device comprises a frame, at least one rail module, a sliding element, and at least one constant force spring. The rail module includes an outer rail and an inner rail, wherein the outer rail is fastened to the frame and formed with a lateral opening for the inner rail sliding therein. The sliding element is formed with an inner space for the rail module penetrating through. The sliding element is secured to the inner rail so as to slide on the frame. The constant force spring is disposed on the top of the frame and connects to the sliding element at a free end thereof. Thus, the elevatable supporting device is characterized in having a slim structure.
