Movable Display Support With Trolley Wheels and Brake Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices are cumbersome and difficult to move manually, especially when they are large and heavy, as they lack a mechanism for easy horizontal movement.
Innovation Solution
Incorporation of a support body with trolley wheel assemblies and stoppers, where the stoppers can be engaged to brake the wheels, allowing the display device to be easily moved horizontally by operating the moving controller, which includes a driver with a knob, screw, gear, and steel wires to switch between moving and braking modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device is made large and heavy to improve display quality, then the display performance is improved, but the ease of moving the device deteriorates
Solution Approach 1:
The support body is divided into a stationary base and a movable platform section. The platform can be separated from the base by lifting it using the screw mechanism, allowing the display device to be moved without moving the entire heavy structure. This segmentation enables the heavy display unit to remain stable while the support platform becomes movable.
Solution Approach 2:
Trolley wheels are introduced as intermediary elements between the platform and the surface it rests on. These wheels enable the platform to be easily moved horizontally across surfaces, solving the problem of moving heavy display devices without requiring direct manual handling of the entire device.
2Device complexity
If manual moving of the display device is used to simplify the structure, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The device includes self-contained moving mechanisms (screw driver, trolley wheels, stoppers) that enable the user to easily move and reposition the display device without requiring external assistance or complex handling procedures. The system serves itself by providing built-in mobility features.
3Ease of operation
If the moving controller allows easy movement of the display body, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The moving controller functions are extracted into separate, simple mechanical components: a screw mechanism for lifting, trolley wheels for horizontal movement, and stoppers for braking. Each component has a single, clear function, avoiding the need for complex integrated control systems while achieving the desired ease of operation.

AI summary
An exemplary display device (2) includes a display body (22) and a support body (23) configured for supporting and moving the display body. The support body includes at least one trolley wheel assembly (28) capable of moving horizontally, and at least one stopper (380) corresponding to the trolley wheel assembly, which is capable of braking the trolley wheel assembly. The display body is moved horizontally when the trolley wheel assembly is moved horizontally.
