Document holder with horizontally displaceable file support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional copy holders cause ergonomic issues such as neck strain and reduced workspace ergonomics due to the need to lean forward to view documents, and they often fail to accommodate heavy files effectively.
Innovation Solution
A desk-based apparatus with a slide and inclined file support that allows horizontal motion above the keyboard, featuring adjustable inclination, anti-slip surfaces, and mechanical stops for secure file positioning, enabling ergonomic document handling without requiring users to adjust their posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the copy holder is arranged next to the keyboard, then the distance between the document and the typist is reduced, but viewing the document results in a torsion of the upper body or the cervical spine which promotes headache and neck pain
Solution Approach 1:
The file support is designed to move horizontally along guide rails rather than being fixed at an angle, allowing the document to be positioned directly in front of the typist in the same horizontal plane as the keyboard, eliminating the need for lateral leaning and body torsion
2Length of moving object
If the copy holder is arranged between the monitor and the keyboard, then the template can be positioned above the keyboard, but the monitor has to be set up into a higher position than necessary which results in a reduced number of degrees of freedom for providing better ergonomics
Solution Approach 1:
The copy holder is divided into separate functional components: a base that remains stationary on the desk, and a file support that moves horizontally on guide rails. This segmentation allows the file support to be positioned optimally above the keyboard without affecting monitor placement or ergonomic adjustments
3Ease of operation
If an inclined file support is used, then the template positioning is facilitated, but the file support cannot accommodate heavy paper files effectively
Solution Approach 1:
The file support structure incorporates a horizontal motion mechanism along guide rails with arrestors, changing the positioning parameter from fixed inclined angles to adjustable horizontal positions. This allows the support to accommodate heavy files effectively while maintaining ease of positioning through the horizontal sliding mechanism
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 apparatus allows for efficient and ergonomic handling of files by maintaining a clear workspace, reducing strain on the neck and accommodating heavy files without obstructing the monitor, thus enhancing user comfort and productivity.
Implementation Method 1
The slide may be slidably attached to or on the base
Implementation Method 2
The base may have—at least in part—an anti-slip-lower surface
Implementation Method 3
The support may provide an inclined plane and/or an adjustable inclination with respect to the slide
Implementation Method 4
The support may comprise a mechanical stop which is arranged to secure the file on the support
