Mobile structure for working with computer equipment in reclining chairs or armchairs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile structures for computer equipment in reclining chairs or armchairs suffer from vibrations and instability when used in reclined positions, causing discomfort during prolonged use.
Innovation Solution
A mobile structure with a main arm and a second folding arm that adjusts angularly with the chair, providing additional support and anchorage through a ratchet mechanism or electric motor, ensuring stability and comfort by offsetting pressure and securing the equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single mobile arm is used to support computer equipment in reclining chairs, then the structure can be simple and easy to operate, but vibrations and instability occur during use
Solution Approach 1:
The patent combines a first mobile arm and a second mobile arm into a unified support structure. Both arms work together to support the computer equipment, with the first arm providing primary support and the second arm providing additional stabilization. This merging of multiple support elements resolves the contradiction by maintaining operational simplicity while eliminating vibrations and instability through distributed support.
2Device complexity
If a single mobile arm is used to support computer equipment, then the device complexity is low, but the structure exhibits vibrations and instability
Solution Approach 1:
The patent merges two mobile arms into a coordinated support system. The first mobile arm and second mobile arm are both coupled to the reclining chair and work together to support the computer equipment. This combination increases structural reliability and eliminates vibrations without requiring complex individual components, as each arm uses simple mobile mechanisms that work in unison.
3Device complexity
If support means are fixed only on one side of the chair, then the structure is simple, but vibrations occur causing discomfort during use
Solution Approach 1:
The patent employs asymmetric positioning of the two mobile arms relative to the chair structure. The first mobile arm is coupled to one side of the reclining chair while the second mobile arm is coupled to the same side but at a different position. This asymmetric arrangement creates a balanced support distribution that eliminates vibrations and instability, resolving the harmful effects while maintaining structural simplicity.

AI summary
Mobile structure for working with computer equipment in reclining chairs or armchairs which, comprising a main mobile arm (2) which incorporates at its distal end (21) support means (3) to incorporate different elements of computer equipment or electronic devices, and the proximal end (22) of which is coupled to a reclining chair or armchair (4) incorporates a movement mechanism (5) the actuation of which determines the rotation of said arm (2) together with said support means (3) to vary its inclination with respect to the seat of the chair (4) in at least two positions of use, and being able to place it in accordance with the reclining position of the chair (4), also comprises a second additional folding arm (6) which, at a first end (61), is coupled in an articulated manner to the chair (4) on the side of said chair opposite to the one to which the main mobile arm (2) is coupled, presenting a folded position of non-use, in which it is flush with the seat (4a) of the chair (4), and a raised position of use in which it is attached by its opposite end (62) to the support means (3) of the computer equipment, serving as support for same as a reinforcement of their anchorage to the main mobile arm (2). Optionally, the additional folding arm (6) is attached at its first end (61) to the front part of the seat (4a) of the chair (4).
