Multi-Monitor Rocker Arm Mount for Ergonomic Chair Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitor holding devices for operator chairs in industrial settings, such as offshore and maritime systems, face challenges with mechanical stress, ergonomic positioning, and ease of entry/exit due to the weight and size of monitors, which often hinder operator movement and cause structural failures under dynamic conditions.
Innovation Solution
A device with an arm arrangement comprising a support structure and rocker arms with restricted rotation, connected by link arms and pivots, allowing the monitors to be positioned ergonomically and shifted between operational and non-operational poses to facilitate entry/exit while distributing load across multiple pivots for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If monitors are mounted on the operator chair to comply with ergonomic requirements, then the operator can view monitors at reading distance, but the device is subjected to high mechanical stress and may fail under dynamic conditions
Solution Approach 1:
The patent implements a dynamic arm arrangement with multiple rocker arms and pivots that allows the monitor holder to move between different positions (operational pose during work, non-operational pose during entry/exit). This dynamic capability resolves the contradiction by enabling ergonomic positioning during operation while maintaining structural integrity through controlled movement paths that reduce mechanical stress on individual components.
Solution Approach 2:
The monitor holding device is segmented into multiple rocker arms (first, second, third rocker arms) connected by pivots, distributing the mechanical load across multiple joints rather than concentrating stress at a single point. This segmentation enhances reliability by preventing failure at any single joint while maintaining ergonomic positioning capabilities.
2Quantity of substance
If multiple monitors are arranged side by side to provide sufficient information display, then the operator can access all process information, but the monitors hinder the operator from entering and exiting the chair easily
Solution Approach 1:
The arm arrangement is designed to be shiftable between operational and non-operational poses. During entry/exit, the monitors can be moved to a non-operational position that clears the path, while during operation, they are positioned to provide sufficient display information. This dynamic reconfiguration resolves the contradiction between having multiple monitors and maintaining ease of entry/exit.
3Manufacturing precision
If monitors are arranged to be directed towards the operator's eyes to avoid glare, then readability is improved, but the operator must move eyes more to view all monitors
Solution Approach 1:
The patent arranges monitors in a three-dimensional configuration using the arm arrangement with multiple rocker arms, positioning them at different angles and depths relative to the operator. This spatial arrangement allows monitors to be directed towards the operator's eyes to avoid glare while distributing them in a configuration that minimizes eye movement, resolving the contradiction between optimal orientation and viewing comfort.
4Adaptability or versatility
If the arm arrangement allows free movement between poses, then adaptability is improved, but the cable connecting monitors experiences increased wear
Solution Approach 1:
The cable is routed along the movement path of the arm arrangement, following the trajectory of the rocker arms and pivots. This dynamic cable routing ensures that the cable moves with the arm arrangement rather than being dragged or twisted, maintaining adaptability while reducing wear and extending cable durability.

AI summary
A device is for holding two or more monitors at an operator chair. The device comprises an arm arrangement adapted to be shifted between different horizontal poses. The arm arrangement comprises a support structure, a first rocker arm, a second rocker arm and a third rocker arm that are rotatably attached at separate locations of the support structure via a respective first pivot, second pivot and third pivot. The support structure is adapted to be attached to or in vicinity of the operator chair. The arm arrangement further comprises a connection arrangement between the first rocker arm, the second rocker arm and the third rocker arm.
