Solution Overview

Problem

Existing display support arm assemblies lack the ability to provide adjustable and stable force throughout the range of vertical adjustment, leading to limited user flexibility and potential instability in mounting displays or other objects.

Innovation Solution

The proposed display support arm assembly incorporates a gas strut and torque elements, along with a unique washer and gasket system to resist rotational movement, allowing for adjustable force and enhanced stability during vertical adjustment, and includes a cable management system for organized cable retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a gas strut is used to provide force throughout the vertical adjustment range, then the stability and user control are improved, but the device complexity increases due to additional components

Engineering Contradiction:
ImprovestabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The gas strut acts as a counterweight mechanism that provides upward force to balance the weight of the display and support arm assembly. This allows the display to be held at any vertical position within the adjustment range, improving stability and user control during positioning operations.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

2Adaptability or versatility

If torque elements are added to provide adjustable force throughout the vertical adjustment range, then the adaptability and user control are improved, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveadjustable forceVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The torque elements provide dynamically adjustable resistance to rotational movement of the support arm. By varying the number or configuration of torque elements, the system adapts to different display weights and user preferences, allowing continuous adjustment of the force required to change vertical position throughout the adjustment range.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the physical parameter of torque resistance by adding or removing torque elements. This allows the same basic mechanism to provide different levels of force resistance, enabling adaptation to various display sizes and weights without redesigning the entire assembly.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If washers and gaskets are used to resist unintended rotational movement, then the stability is improved, but the device complexity and manufacturing precision requirements increase

Engineering Contradiction:
ImprovestabilityVSAvoidmanufacturing precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The gasket is positioned between the first and second washers to provide friction-based resistance against unintended rotational movement. This cushioning effect prevents slippage and maintains the desired orientation of the support arm relative to the display, ensuring stability during operation.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Adaptability or versatility

If a cable management extension with loop portion and keeper is added, then the adaptability and organization are improved, but the device complexity increases

Engineering Contradiction:
Improvecable managementVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable management extension serves multiple functions: it provides structural support as part of the upper support arm, manages cables through the loop portion to prevent tangling during rotation, and uses the keeper to secure cables in place. This multi-functional design improves adaptability without requiring separate cable management components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
