Stand for supporting a computing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The prevalent use of laptops at a lower screen position leads to head-down user posture, contributing to repetitive use injuries due to prolonged computer use.
Innovation Solution
A portable, collapsible stand that elevates the laptop screen to near eye-level, featuring rotating legs with gripping mechanisms, high-tack resting surfaces, and a scissor mechanism for easy adjustment and portability, allowing users to maintain an ergonomically correct working position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the laptop screen is positioned at a lower height (one to three feet below eye level), then the laptop can be placed on a standard desk or table, but this positioning forces a head-down user posture that contributes to repetitive use injuries
Solution Approach 1:
The stand acts as an intermediary device between the laptop and the user, elevating the laptop to an ergonomic height. The stand includes support legs with gripping mechanisms that attach to the laptop chassis, and cross-members that position the laptop at the correct height, thereby mediating the interaction between the laptop and user to eliminate the harmful head-down posture
Solution Approach 2:
The stand introduces a vertical dimension adjustment by elevating the laptop from the horizontal desk surface to a higher position that aligns the screen with the user's eye level. This dimensional change transforms the workspace geometry to achieve ergonomic positioning without requiring the user to change their posture
2Reliability
If the stand includes multiple components such as rotating legs, gripping mechanisms, sliding mechanisms, and cross-members, then the stand provides stable and adjustable support, but the device complexity increases
Solution Approach 1:
The stand is divided into distinct functional segments: support legs with gripping mechanisms for attachment, sliding mechanisms for height adjustment, cross-members for structural stability, and rotating legs for positioning. Each segment performs a specific function, allowing the complex system to be managed through modular functional decomposition
Solution Approach 2:
The stand incorporates dynamic elements including sliding mechanisms that allow height adjustment, rotating legs that enable positioning adjustments, and ratcheting stoppers that provide stable locking positions. These dynamic features allow the stand to adapt to different ergonomic requirements while maintaining stability when locked in position

AI summary
A stand for supporting a computing device and a method of assembling the stand are provided. The stand may support the computing device at a height such that a screen of the computing device is at or near eye-level of a user. The stand may include a frame member and a gripping mechanism attached to an end of the frame member. The gripping mechanism may secure the computing device to the stand.
