Posture-Sensing Desk and Chair Control for Ergonomic Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ergonomically designed computer desks often require manual and inflexible adjustments, failing to adapt to users' changing postures over time, leading to discomfort and pain due to prolonged standing or sitting.
Innovation Solution
An intelligent computer desk and chair system equipped with a control unit and image sensing devices that automatically adjust the position of the desk and chair based on user posture, sending control signals to move the carriage and chair to optimize user comfort and posture changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the height of the computer desk is manually adjusted to comply with ergonomic requirements, then the user can work in a standing position to release shoulder, neck, or hips tensions, but the adjustment is inconvenient and inflexible as it can only be done in one single direction
Solution Approach 1:
The patent implements a carriage system that can dynamically adjust between sitting and standing positions automatically. The carriage moves along a guide rail to change the desk height, allowing the user to switch between seated and standing postures without manual intervention, thus resolving the contradiction between adaptability and ease of operation
Solution Approach 2:
The system incorporates sensors that automatically detect user posture and trigger carriage movement to adjust desk height accordingly. The desk serves itself by automatically adapting to the user's needs without requiring manual adjustment, eliminating the inconvenience of single-direction manual adjustment while maintaining full ergonomic adaptability
2Adaptability or versatility
If the desk height is fixed to maintain a specific working posture, then the structure is simple and stable, but the user experiences discomfort and pain due to prolonged maintenance of the same posture
Solution Approach 1:
The patent introduces a movable carriage system that enables the desk to transition between fixed (seated) and dynamic (standing) states. The carriage moves along a guide rail and can be positioned at different heights, allowing posture variation while maintaining structural stability through the guided movement mechanism
Solution Approach 2:
The desk is divided into a stationary base and a movable carriage component. The carriage contains the computer and can be independently moved along the guide rail, separating the stable support function from the adjustable positioning function, thus enabling posture variation without compromising overall structural simplicity
3Productivity
If the computer desk is designed with adjustable height for ergonomic compliance, then it can accommodate standing position work, but the adjustment mechanism requires manual operation which is time-consuming and interrupts workflow
Solution Approach 1:
The system uses sensors to automatically detect when the user needs to change posture and triggers the carriage movement accordingly. This self-service mechanism eliminates the need for manual adjustment, preventing workflow interruption and reducing the time lost to posture changes, thus improving productivity
Solution Approach 2:
The patent incorporates sensors that provide feedback about user posture and automatically trigger carriage adjustment. This closed-loop feedback system ensures the desk adapts to user needs in real-time without requiring manual input, maintaining workflow continuity and minimizing adjustment time

AI summary
An intelligence computer desk and chair system includes a platform, a carriage, and a control unit. The carriage is located on the platform. The control unit is electrically connected to the carriage. The control unit controls the carriage to move relative to the platform according to a built-in program.
