Wall-Mounted Accessory Holder With Counterbalance Ergonomic Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to provide ergonomic positional adjustment for integrated input and output devices, such as video displays and keyboards, which are often mounted together in limited spaces like hospitals or offices, leading to user discomfort and increased risk of musculoskeletal disorders due to improper posture.
Innovation Solution
A positionally adjustable accessory holder with a vertical track, roller assemblies, and counter-balance mechanisms that allow for three-dimensional adjustment of devices, including a U-shaped carriage with friction-reducing bearing assemblies and a counter-balance system using constant force springs, enabling effortless vertical positioning and relative adjustment between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If input and output devices are integrated and mounted together in limited spaces, then space utilization is improved, but ergonomic positioning capability deteriorates
Solution Approach 1:
The patent applies dynamics by making the mounted devices movable rather than fixed. The roller assembly with wheels allows the input device (keyboard) to move vertically along the mounting surface, and the articulating arm enables the output device (display) to pivot and adjust its position. This dynamic capability provides ergonomic positioning while maintaining compact integration.
Solution Approach 2:
The patent introduces additional dimensions of adjustment beyond simple horizontal placement. The vertical track adds vertical movement capability, while the articulating arm adds rotational and angular adjustment dimensions. This multi-dimensional positioning capability enables ergonomic adaptation within a compact footprint.
2Device complexity
If devices are fixed in rigid positions to simplify mounting, then device complexity is reduced, but user comfort and ergonomics deteriorate
Solution Approach 1:
The patent transforms fixed rigid mounting into dynamic adjustable mounting. The roller assembly provides vertical mobility with simple wheel-based mechanics, and the articulating arm provides angular adjustment through pivot joints. These dynamic mechanisms maintain relatively simple construction while dramatically improving user comfort and ergonomics.
Solution Approach 2:
The patent employs counterbalance springs in the articulating arm mechanism to offset the weight of the display device. This counterweight mechanism enables easy positioning and adjustment without requiring significant user force, maintaining simplicity while enhancing ease of operation.
3Area of stationary object
If multiple devices are mounted in close proximity, then space efficiency is improved, but adjustment range for each device deteriorates
Solution Approach 1:
The patent compensates for limited horizontal space by introducing vertical and angular dimensions of adjustment. The roller assembly enables vertical movement along the mounting surface, while the articulating arm provides rotational and angular adjustment capabilities. This multi-dimensional approach maintains compact horizontal footprint while expanding overall adjustment range.

AI summary
Accessory holders useful for facilitating the support and positional adjustment of secured accessories. More particularly, a positionally adjustable accessory holder for use with one or more accessories, preferably input or output devices, such as video displays, monitors, keyboards, keypads, laptops and the like. The accessory holder further allows for easy three-dimensional adjustment of two such devices to place the devices in relative positions more ergonomically desirable for a variety of users and workspaces, and features a counter-balance mechanism for balancing the weight of the secured accessories.
