Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display supporting apparatuses have limitations in height adjustment range, compatibility with different display sizes and loads, inconvenient height adjustment methods, unstable fixation to surfaces, and restricted installation environments due to limited rotation ranges and poor structural design.
Innovation Solution
A display supporting apparatus with a clamp unit, pillar unit, neck unit, arm unit, and connection unit that allow for adjustable height, wide rotation ranges, and stable fixation, featuring a coil spring with adjustable tension to accommodate various display sizes and loads, and a design that enables easy installation near walls by fitting into cable through-holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the elastic force of the spring is fixed, then the structure is simple, but it can only support one type of display device with limited compatibility
Solution Approach 1:
The spring elastic force is made adjustable rather than fixed, allowing the supporting apparatus to adapt to different display device weights and sizes. The adjustment mechanism enables dynamic modification of the spring tension to match various load requirements.
Solution Approach 2:
The elastic force parameter of the spring can be changed by adjusting its pre-tension or replacing it with springs of different stiffness. This allows the same apparatus to support display devices of varying weights and dimensions without structural redesign.
2Ease of operation
If the fixing portion is loosened for height adjustment, then the arm portion can be repositioned, but the display panel may descend due to load
Solution Approach 1:
The spring is pre-loaded with elastic force before the fixing portion is loosened. This preliminary action ensures that when the fixing is released, the spring immediately provides upward force to counteract the display panel's weight, preventing unintended descent during adjustment.
Solution Approach 2:
The spring acts as a cushioning element that compensates for the instability caused by loosening the fixing portion. It provides continuous force support during the transition state, preventing the display panel from dropping while allowing repositioning.
3Ease of operation
If the pressure plate area is small, then the clamp unit structure is compact, but the supporting apparatus is not stably fixed to the desk
Solution Approach 1:
The clamp unit employs an asymmetric design where a small pressure plate concentrates force on a specific point of the desk edge, while the bracket provides a larger contact area on the opposite side. This asymmetric force distribution achieves both compact structure and stable fixation.
Solution Approach 2:
The pressure plate and bracket are designed with curved surfaces that conform to the desk edge geometry. This curvature allows the small pressure plate to effectively engage with the desk edge, distributing localized pressure to achieve stable fixation without requiring a large contact area.
4Adaptability or versatility
If the bracket must be coupled to the desk edge, then the installation position is restricted, but the clamp unit can be mounted near walls
Solution Approach 1:
The clamp unit is designed with a universal mounting mechanism that can adapt to different installation environments. It can clamp onto desk edges when installed in open positions, or engage with wall surfaces when installed near walls, providing multi-functional installation capability.
Solution Approach 2:
The clamp unit incorporates adjustable and movable components that allow it to adapt its configuration based on the installation environment. The dynamic structure enables transformation between edge-clamping mode and wall-mounting mode, expanding installation flexibility.
