Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional frame stands for display panels are limited in adjustable tilting angles, cannot switch between landscape and portrait modes, and may not sustain the shock applied by users, leading to potential shaking and eye strain.
Innovation Solution
A frame stand design featuring a board, first and second shafts, an interface plate, and a supporting rack that allows flexible adjustment of viewing angles, enabling switching between landscape and portrait modes, with a guiding groove and member for controlled rotation, and a returning unit for stability, reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional frame stand uses a fixed return module, then the structure is simple, but the tilting angle is limited to maximum 60° and cannot be freely adjusted
Solution Approach 1:
The frame stand is divided into multiple functional modules: a return module for tilting adjustment, a rotating module for orientation switching, and a supporting rack for stability. Each module independently provides a specific function, allowing the overall system to achieve greater adaptability while managing complexity through modular design.
Solution Approach 2:
The frame stand incorporates dynamic adjustment capabilities through the return module which allows continuous tilting angle adjustment within a wide range (not limited to 60°), and the rotating module which enables switching between different orientations. This dynamic adaptability resolves the contradiction by making the structure adjustable rather than fixed.
2Adaptability or versatility
If a conventional frame stand allows only fixed orientation, then the structure is simple, but the display panel cannot switch between landscape and portrait modes
Solution Approach 1:
The orientation switching function is implemented as a separate rotating module that connects the display panel to the supporting rack. This modular approach allows the rotating module to handle orientation changes independently, enabling landscape and portrait mode switching without complicating the overall frame stand structure.
Solution Approach 2:
The rotating module serves multiple functions: it enables orientation switching between landscape and portrait modes, provides additional support stability, and works in conjunction with the return module for comprehensive position adjustment. This multi-functionality achieves versatility while maintaining structural efficiency.
3Reliability
If a conventional frame stand lacks shock absorption, then the structure is simple, but user tapping causes considerable shock and shaking
Solution Approach 1:
The supporting rack is designed with shock-absorbing characteristics and friction-based stabilization elements that preemptively cushion against user tapping and shaking. The rack's structure and connection methods are configured to absorb and dissipate shock before it propagates to the display panel, ensuring stability during normal use.
Solution Approach 2:
The frame stand utilizes friction between the supporting rack and the display panel, as well as between rack feet and the supporting surface, to convert the harmful effect of tapping into beneficial stabilization. The friction forces generated during normal interaction help dampen vibrations and reduce shaking, turning potential instability into enhanced stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The frame stand provides flexible and stable support for display panels, allowing adjustable viewing angles and orientations, reducing eye strain and manufacturing costs through a simple and effective design.
Implementation Method 1
The first shaft connects the board while the interface plate pivotally connects to the board by the first shaft. Thus the interface plate can rotate to a first angle in respect to the board.
Implementation Method 2
The supporting member can swing by using the second shaft as an axis to a second angle and therefore the distance between the second shaft and the working surface varies.
Implementation Method 3
The guiding groove is formed on the interface plate. One end of the guiding member connects the board while the other end fits to the guiding groove. When the interface plate rotates to the first angle, the guiding member moves along the guiding groove.
Implementation Method 4
The returning unit connects the interface plate and pivotally connects the supporting member to provide a return force to the supporting member.
Implementation Method 5
The stop enhances the friction when the supporting member rests on the working surface.

AI summary
A frame stand includes a board, an interface plate and a supporting rack. The board is mounted on a display panel. The interface plate pivotally connects the board by a first shaft. The interface plate rotates in parallel with respect to the board and form a first rotate angle. The supporting rack connects the interface plate and has a second shaft and a supporting member. The supporting member swings a second angle by using the second shaft as an axis. The second shaft selectively approaches or moves away from a working surface. The frame stand switches between a first state and a second state. In the first state, the supporting member and the first side of display panel rest on the working surface. In the second state, the supporting member and the second side of display panel rest on the working surface.
