Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beds fail to automatically adjust to maintain the human spine's normal physiological curve, leading to poor sleep quality and potential health issues due to inadequate support for the head, neck, and shoulders.
Innovation Solution
An intelligent adjustable supporting module comprising an induction spring, an outer ring spring, and a sensor, with limiting blocks and an induction plate, which allows independent pressure detection and distribution to maintain the spine's curve, reducing noise and enhancing comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single spring structure is used for pressure detection, then the device complexity is reduced, but the reliability and protection of the sensor and spring under extreme pressure deteriorates
Solution Approach 1:
The patent implements a nested spring structure where an inner ring spring is placed inside an outer ring spring. The inner ring spring is directly connected to the sensor for pressure detection, while the outer ring spring provides additional support and protection. This nested configuration allows the system to handle extreme pressure more reliably while maintaining a relatively compact design.
Solution Approach 2:
The spring support system is segmented into two independent ring springs (inner and outer) that can function separately or together. The inner ring spring handles normal pressure detection, while the outer ring spring activates under extreme pressure conditions. This segmentation allows each component to be optimized for its specific function and provides redundancy for improved reliability.
2Device complexity
If the inner ring spring and outer ring spring are in contact, then the structural complexity is reduced, but the noise generation under extreme pressure increases
Solution Approach 1:
The patent introduces an induction plate as an intermediary component between the inner ring spring and outer ring spring. This plate prevents direct contact between the two springs while allowing them to function independently. The induction plate acts as a mediator that maintains separation to avoid noise-generating collisions, especially under extreme pressure conditions when both springs are heavily compressed.
3Device complexity
If existing beds are used without automatic adjustment, then the device complexity is low, but the ability to maintain the human spine's physiological curve deteriorates
Solution Approach 1:
The patent incorporates sensors connected to the spring system that detect pressure distribution across the bed surface. This feedback information is used to automatically adjust the bed's supporting surfaces to maintain the human spine's physiological curve. The system continuously monitors and adapts to the user's body shape and position, providing customized support without requiring manual intervention.
Solution Approach 2:
The bed system transitions from a static structure to a dynamic, automatically adjustable system. The supporting surfaces can move and change position based on real-time pressure detection, allowing the bed to adapt to different sleeping positions and body types. This dynamic capability enables the bed to maintain the spine's natural curve throughout the night regardless of position changes.
