Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting arm structures for screens face challenges in supporting different loads, positioning screens at various heights, and maintaining sterility in environments like hospitals, where connecting power and cabling complicates maintaining a sterile environment.
Innovation Solution
The design incorporates a core arm with a non-adjustable gas spring counterbalance and friction elements for up/down resistance, allowing for adjustable positioning and concealed cable routing, along with joint rotation stop structures to prevent cable winding and collisions, enabling 360-degree rotation and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mounting arm structures are used to support screens, then screen support capability is improved, but adaptability to different loads and heights is worsened
Solution Approach 1:
The mounting arm structure incorporates adjustable components including height adjustment mechanisms and rotation joints that allow the arm to adapt to different loads and positioning requirements. The gas spring counterbalance system provides dynamic adjustment capability to maintain balance across various configurations.
Solution Approach 2:
The system enables parameter changes through adjustable height positions, variable rotation angles, and modifiable load capacity settings. These parameter adjustments allow the mounting arm to accommodate different screen sizes, weights, and positioning requirements while maintaining structural integrity.
2Adaptability or versatility
If power and cabling are connected to support arms, then screen functionality is improved, but maintaining sterile environment is worsened
Solution Approach 1:
Cables are routed through the hollow interior of the mounting arm structure, nesting the cabling system within the arm's body. This concealed routing eliminates exposed cables that could compromise sterile environments while maintaining full electrical connectivity for screen functionality.
Solution Approach 2:
The mounting arm incorporates sealed cable access points and protective barriers that prevent contamination along cable pathways while allowing electrical connections to pass through, thus maintaining sterile barriers without sacrificing functionality.
3Reliability
If rotation stop structures are added to prevent cable winding, then cable protection is improved, but device complexity is worsened
Solution Approach 1:
The rotation stop structures are integrated into the existing joint mechanisms of the mounting arm, combining cable protection functionality with the structural components already present. This merging approach provides cable protection without adding separate, independent systems that would increase overall complexity.

AI summary
Structures and systems are disclosed for supporting tablets or displays. A core arm that is configured to have a range of rotation based on angle length of a track or tunnel, an angle length of a joint rotation stop structure, and an angle length of a floating stop key. The core extends from a rear end to a front end of the structure. The core arm can also include a floating stop key that is movable with the track or tunnel of the core arm structure. The structures and systems can thus be readily configured for light or heavy configurations, with or without the use of an extension arm, and can conceal cable routing, which is accessible, via snap fit covers, for easy installation and maintenance.
