Touch Screen Support Arms for Variable Ground Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for large touch screens face difficulties in navigating uneven floors and obstacles due to fixed ground clearance, making them hard to move over small steps or inclined ramps, which hinders their deployment in external operational sites.
Innovation Solution
A support device with oscillating arms equipped with gas springs and directional wheels, allowing adjustable ground clearance and enhanced stability, facilitating easy transport and deployment on varied terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the support device has a fixed ground clearance, then it provides stable support for the touch screen, but it becomes difficult to move on floors with variations in level such as steps or inclined ramps
Solution Approach 1:
The support device employs oscillating arms that can dynamically adjust their angle relative to the base, transforming the fixed ground clearance into a variable parameter. This allows the device to adapt its ground clearance to different terrain conditions while maintaining stability during operation
Solution Approach 2:
The device changes the parameter of ground clearance by allowing the oscillating arms to pivot between different angular positions. This parameter change enables the base to either elevate for mobility or lower for stability depending on operational requirements
2Adaptability or versatility
If the support device uses oscillating arms with elastic means, then it achieves variable ground clearance for easy transport, but it requires additional locking means to maintain position
Solution Approach 1:
The elastic means (gas springs) automatically provide the force necessary to maintain the oscillating arms in their desired angular positions without requiring active control systems. The locking means simply needs to hold the position, while the elastic elements do the work of maintaining that position against gravitational and operational forces
3Ease of operation
If the support device has directional wheels, then it improves steering capability, but it increases the complexity of the wheel assembly
Solution Approach 1:
The wheel assembly is segmented into distinct functional components: the wheel itself, the directional control mechanism, and the connection to the oscillating arm. This segmentation allows each component to be optimized independently while simplifying the overall design and maintenance of the steering system
