Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding mount systems for electronic displays face challenges in resisting rotational forces, which require loosening a clamp to slide the mount, leading to potential rotation or shifting, necessitating the user to lift the display for adjustment.
Innovation Solution
A double-beam support structure with parallel horizontal bars and a bracket that resists rotation, featuring a releasable clamp jaw and plain bearings to facilitate sliding without lifting the display, ensuring secure and easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a clamp or fastening mechanism squeezes the support bar to resist rotation, then the rotational stability is improved, but the friction increases and prevents sliding
Solution Approach 1:
The invention transitions from a single support bar to a double support bar configuration, adding a vertical dimension to the support structure. The bracket engages both bars simultaneously, distributing the rotational resistance across two separate contact points rather than one, thereby reducing the squeezing force needed on each individual bar and minimizing friction during sliding operations.
Solution Approach 2:
The patent introduces an intermediary mechanism between the bracket and support bars - a bearing surface or sliding interface that facilitates smooth movement. This intermediary element reduces direct friction between the bracket and support bars, allowing the clamp to maintain rotational stability without creating excessive friction that would prevent sliding.
2Ease of operation
If the clamp squeezing force is reduced to enable sliding, then the sliding ease is improved, but the mount rotates or shifts forward
Solution Approach 1:
By utilizing two vertically-spaced support bars instead of one, the system creates additional geometric constraints on the bracket. The bracket's engagement with both bars simultaneously provides inherent positional stability, preventing forward rotation or shifting even when the clamp squeezing force is reduced to levels that allow easy sliding.
Solution Approach 2:
The invention combines the functions of rotational restraint and positional stabilization into a unified double-bar system. The bracket's interaction with both support bars simultaneously addresses both rotational stability and prevention of forward shifting, allowing the clamp to use minimal squeezing force while maintaining both functions.
3Adaptability or versatility
If the user supports the weight of the display to slide it, then the position adjustment capability is improved, but the ease of operation deteriorates
Solution Approach 1:
The bearing surface or sliding interface acts as an intermediary that reduces friction between the bracket and support bars to such an extent that the weight of the display becomes irrelevant during sliding operations. The reduced friction coefficient allows the bracket to slide along the bars with minimal force, eliminating the need for the user to manually support the display weight.
4Device complexity
If a single support bar is used, then the device complexity is reduced, but the ability to resist rotational force deteriorates
Solution Approach 1:
The transition from a single horizontal support bar to two vertically-spaced parallel bars adds a vertical dimension to the support structure. This dimensional change creates a more robust geometric configuration that inherently resists rotational forces applied to the bracket, with each bar providing independent contact points that collectively counteract torque.
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 double-beam support system securely positions the display while allowing easy lateral adjustment without the need to lift the display, reducing friction and preventing binding, thus enhancing user convenience and stability.
Implementation Method 1
The strength and rigidity of the mounting system depend in part on the ability of the support bar to resist the tendency of the mount to rotate forward
Implementation Method 2
The clamp or other fastening mechanism resists the rotational tendency of the mount by squeezing the support bar
Implementation Method 3
This is significant because, in addressing the need to slide the mount along the support bar, a squeezing force at the surface of the support bar creates more friction and prevents sliding
Implementation Method 4
A double-beam support structure with parallel horizontal bars and a bracket that resists rotation, featuring a releasable clamp jaw and plain bearings to facilitate sliding without lifting the display

AI summary
A mounting system includes a double-beam support structure comprising two parallel, horizontal bars spaced apart vertically, and a bracket designed to hang from the double support bars while resisting rotation about the support bars. The bracket is slidably positionable along the support bars and may further include a releasable clamp jaw for clamping one of the support bars to selectively fix the position of the bracket along the support bars. The bracket may support a mounting assembly for an electronic visual display, an extension boom assembly, or another item.
