Technique for adjusting the posture of a seated person
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable chairs lack the ability to inform users of their posture and may inadvertently be adjusted to facilitate health-adverse positions, leading to chronic health issues due to unawareness of their seating posture.
Innovation Solution
A posture adjustment system that uses sensor arrays and a computing device to monitor and analyze the user's posture, compare it to ergonomic models, and either notify the user or adjust the chair to correct unhealthy postures, thereby improving seating habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional adjustable chairs are manually adjusted by users, then the chair can be configured to support specific postures, but the user may incorrectly adjust the chair to facilitate health-adverse postures due to lack of awareness
Solution Approach 1:
The system continuously monitors user posture using sensor arrays and provides real-time feedback through notifications when health-adverse postures are detected. This closed-loop feedback mechanism enables the chair to automatically correct postures by adjusting its configuration, resolving the reliability issue of manual adjustment while preserving ease of operation through automated control.
Solution Approach 2:
The chair performs self-adjustment based on sensor data and posture analysis, eliminating the need for user intervention in posture correction. The system autonomously monitors, analyzes, and adjusts chair configuration to maintain healthy postures, transforming the chair from a passive manually-adjusted object to an active self-correcting system.
2Reliability
If sensor arrays and computing devices are added to monitor and adjust posture, then posture correction effectiveness is improved, but device complexity increases
Solution Approach 1:
The computing device performs multiple functions including sensor data acquisition, posture analysis, correction determination, and chair control. This multi-functionality consolidates complex operations into a single integrated system, managing device complexity while maintaining high posture correction effectiveness through centralized intelligent control.
Solution Approach 2:
The system merges sensor arrays, computing devices, and chair adjustment mechanisms into an integrated posture management system. By combining these components into a unified system with centralized control logic, the patent manages complexity through integration while achieving reliable automated posture correction.
3Reliability
If the system automatically adjusts the chair based on sensor data, then healthy postures are promoted, but the user may not be aware of their posture habits
Solution Approach 1:
The system provides dual feedback: automatic chair adjustment feedback through physical reconfiguration and informational feedback through user notifications. This dual feedback mechanism both corrects postures automatically and informs users of their posture habits, preventing information loss while maintaining correction effectiveness.
Solution Approach 2:
The system performs preliminary analysis of posture data and provides advance notifications to users about their posture habits before automatic correction occurs. This preliminary informational action ensures users are aware of their posture issues while the system prepares to implement corrective adjustments.
Data Source
AI summary
A posture adjustment system includes a set of sensors coupled to a chair on which a person may sit. The posture adjustment system gathers data from the set of sensors and generates a posture model that reflects a posture associated with the seated person. The posture adjustment system then determines corrections to the posture of the person that could, potentially, improve their posture. The posture adjustment system then indicates those corrections to the person, or, alternatively, applies a set of adjustments to the chair to cause the person to assume a new posture that reflects the posture corrections.
