Solution Overview
Problem
Current wearable sitting-posture assisting devices lack comfort, ergonomics, and safety due to complex and tool-dependent coupling mechanisms, which hinder quick and easy transitions between sitting and standing postures, and can cause unwanted loading on joints.
Innovation Solution
A wearable sitting-posture assisting device with a quick coupling system that allows tool-less, one-handed coupling and uncoupling of shoe adapters and connectors, featuring a combination of magnetic and latch elements, and a bearing unit that enables translational movement of the foot unit, enhancing comfort and safety by simplifying posture changes and reducing joint loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex coupling mechanism is used to connect shoe adapter and shoe connector, then the connection strength and reliability are improved, but the ease of operation and wearing comfort deteriorate due to tool dependency and difficulty in quick coupling/uncoupling
Solution Approach 1:
The patent replaces complex mechanical coupling mechanisms with a magnetic coupling system. The shoe adapter and shoe connector are equipped with magnetic elements that automatically attract and secure the components together without requiring tools or complex manual operations, thereby maintaining connection reliability while dramatically improving ease of operation.
Solution Approach 2:
The magnetic coupling system enables self-aligning and self-securing of the shoe adapter and shoe connector. The magnetic attraction automatically guides the components into proper alignment and maintains secure connection without requiring external tools or complex manual intervention, making the coupling process intuitive and tool-less.
2Reliability
If a secure coupling mechanism is used to ensure stable connection, then the operational safety is improved, but the ease of uncoupling in emergency situations or when changing postures deteriorates due to strong binding force
Solution Approach 1:
The magnetic coupling system provides dynamic connection characteristics where the magnetic force maintains secure binding during normal use but allows for quick release when needed. The magnetic attraction strength is sufficient to ensure operational safety during sitting and standing, but can be easily overcome by simple manual intervention when uncoupling is required for posture changes or emergencies.
Solution Approach 2:
The patent replaces traditional mechanical locking mechanisms with magnetic coupling, which provides inherent security through magnetic attraction while allowing for effortless uncoupling. The magnetic field maintains stable connection during operation but can be easily disrupted by simple manual actions, enabling quick release without tools or complex procedures.
3Stability of the object's composition
If a rigid coupling structure is used to ensure stable connection between foot unit and leg unit, then the structural stability is improved, but the adaptability to different postures (sitting, standing, walking) deteriorates due to inability to accommodate movement variations
Solution Approach 1:
The patent employs dynamic coupling mechanisms including magnetic elements and movable bearing units that allow the foot unit to adapt its position relative to the leg unit. The magnetic coupling provides stable connection while the bearing units enable translational movement, allowing the system to maintain structural stability during sitting and standing while adapting to different posture requirements.
Solution Approach 2:
The coupling system is divided into separate functional components: magnetic coupling elements for secure connection, bearing units for controlled movement, and adjustable components for position variation. This segmentation allows each component to perform its specific function - maintaining stability through magnetic attraction while enabling adaptability through movable bearing units and adjustable elements.
4Manufacturing precision
If tool-dependent coupling mechanisms are used to ensure precise connection, then the manufacturing precision is improved, but the productivity and time efficiency deteriorate due to requirement for tools and complex assembly procedures
Solution Approach 1:
The patent replaces tool-dependent mechanical coupling with a magnetic coupling system that requires no tools for assembly or disassembly. The magnetic elements automatically align and secure the shoe adapter and shoe connector with precise positioning, eliminating the need for tools while maintaining connection precision, thereby dramatically improving coupling speed and productivity.
Solution Approach 2:
The magnetic coupling system performs self-alignment and self-securing of the components. The magnetic attraction automatically guides the shoe adapter and shoe connector into precise alignment and maintains secure connection without requiring external tools or complex assembly procedures, enabling rapid coupling and uncoupling operations.
