Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged sitting leads to various physical issues such as posture problems, blood circulation issues, muscular and skeletal pain, and early mortality, as people spend extended periods seated due to lifestyle or necessity, with existing seating technologies failing to adequately address these concerns.
Innovation Solution
A chair with synchronized motion mechanisms that induce contra-lateral shoulder and pelvic movements, utilizing actuators like hydraulic or pneumatic systems to mimic walking motions, and incorporating sensors and processors for adjustable and therapeutic effects, which can be integrated into or attached to various seating types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If people sit for extended periods, then productivity and convenience are improved, but physical health deteriorates due to posture problems, pressure sores, and circulation issues
Solution Approach 1:
The chair incorporates actuators that dynamically adjust the seat and backrest positions, transforming a static seating system into a dynamic one that can actively counteract the harmful effects of prolonged sitting through synchronized movements mimicking walking motions
Solution Approach 2:
The system employs periodic actuators that cycle through synchronized seat and backrest movements, creating rhythmic motions that simulate walking patterns and provide continuous physical stimulation to prevent health deterioration during extended sitting
2Ease of operation
If existing seating technologies are used, then basic comfort is provided, but they fail to adequately address posture problems and circulation issues
Solution Approach 1:
The chair is divided into independently controllable segments including the seat platform and backrest, each capable of synchronized movement with precise control over their respective motions to address specific physical issues
Solution Approach 2:
The system incorporates sensors that detect user behavior and intent, providing feedback to the controller to adjust actuator operations and customize the synchronized movements to better address individual user needs and prevent physical deterioration
3Object-affected harmful factors
If actuators are added to enable synchronized movements, then health benefits are improved, but device complexity increases
Solution Approach 1:
The patent employs pneumatic or hydraulic actuators that utilize fluid pressure to generate the required forces for synchronized seat and backrest movements, providing smooth and controlled motion while managing system complexity through well-established mechanical principles
