Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display swivel arms for information handling systems are cumbersome to set up and move, often requiring tools and causing clutter in small workspaces due to their complexity and weight, and they can invade neighboring spaces or collide with furniture.

Innovation Solution

A tool-less swivel coupling device that rotationally couples a swivel arm to an anchor and display support arm, using a pin and slot mechanism for secure assembly and disassembly without tools, allowing for adjustable rotational movement and preventing accidental disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional display swivel arms are used with multiple rotating components and tools for assembly, then the display can be positioned at various angles and locations, but the setup becomes time-consuming and difficult

Engineering Contradiction:

Improvedisplay positioning flexibilityVSAvoidassembly ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The swivel arm is divided into modular components (mounting bracket, swivel arm, display support arm, counterweight) that can be independently manufactured and assembled. Each component has standardized interfaces that simplify assembly while maintaining positioning flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system incorporates multiple rotating joints with different degrees of freedom (azimuth rotation, elevation rotation, display tilt) that allow dynamic positioning. The counterweight mechanism provides dynamic balance compensation during movement.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If display swivel arms are designed with complex assembly requirements and multiple loose parts, then adjustable positioning is achieved, but the setup process becomes cumbersome and parts are easily lost

Engineering Contradiction:

Improveposition adjustment capabilityVSAvoidassembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Standardized interfaces and components are designed to serve multiple functions. The mounting bracket can accommodate different display types and sizes. The swivel arm structure provides both support and positioning functions. Fasteners are designed to both secure components and allow easy disassembly.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple functions are combined into single components where possible. The mounting bracket integrates clamp mechanism, mounting holes, and adjustment features. The display support arm combines support structure, positioning mechanism, and connection interface.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If display swivel arms are used in small office spaces, then displays can be elevated above the desktop, but the swivel arm may invade neighboring work space or collide with adjacent furniture

Engineering Contradiction:

Improvedesktop space clearanceVSAvoidworkspace intrusion

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The swivel arm incorporates rotating joints that allow the display to be positioned dynamically above the desktop surface. The azimuth and elevation adjustments enable the display to clear the desktop while the counterweight maintains balance during repositioning.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system allows adjustment of multiple parameters (azimuth angle, elevation angle, display height, counterweight position) to optimize the display position. These parameter changes enable the display to be positioned in three-dimensional space above the desktop, clearing the work surface while avoiding collision with surrounding furniture.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If traditional display swivel arms require tools and multiple assembly steps, then secure assembly is achieved, but the setup time increases significantly

Engineering Contradiction:

Improveassembly securityVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The assembly process is segmented into simple, discrete steps with standardized components. Each component can be independently positioned and secured. The modular design allows assembly to proceed in a logical sequence without requiring complex tool operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system incorporates self-aligning features and self-securing mechanisms. Components are designed to guide themselves into proper alignment during assembly. Fasteners are designed to secure components automatically without requiring complex tool operations or multiple adjustment steps.

Inventive Principle:

Principle #25Self-service

AI summary

An information handling system display swivel arm rotates about two axes with selectable amounts of rotation. The swivel arm couples to an anchor and a display support with a tool-less swivel coupling device having a member inserted into a housing and rotationally coupled in place by first and second pins that engage first and second slots of the member. The first slot is disposed around the circumference of the member to support substantially 360 degrees of rotation of the member in the housing. The second slot is disposed only part of the way around the circumference of the member to support partial rotation, such as 180 degrees. Removal of both pins from the member allows withdrawal of the member from the housing to disassemble the swivel arm.
