Solution Overview
Problem
Conventional spring mattresses lack adjustability in firmness, leading to discomfort due to vibration transmission and inability to customize firmness for individual users, and they often suffer from moisture issues that can lead to mold and mite contamination.
Innovation Solution
A bed design featuring a cushion module with adjustable firmness adjusters and a drying module that blows air to dry the mattress, allowing for customizable firmness and improved hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional spring mattresses are used, then the structure is simple and cost-effective, but the firmness cannot be adjusted and vibrations are transmitted between users
Solution Approach 1:
The mattress is divided into multiple independently controllable zones, each with adjustable firmness. The support system is segmented into multiple actuators that can independently adjust the firmness of different mattress regions, allowing customization for each user's preferences and body areas.
Solution Approach 2:
The mattress transitions from a static structure to a dynamic system with adjustable firmness. Electric actuators enable real-time modification of spring pre-loads and support forces, allowing the mattress to adapt its characteristics based on user needs, time of day, or environmental conditions.
2Adaptability or versatility
If fixed firmness mattresses are used, then the structure is simple, but different users cannot have customized firmness preferences
Solution Approach 1:
The system provides automated firmness adjustment through controllers that can operate independently or in response to user input. Sensors detect user presence and preferences, and the control system automatically adjusts actuator positions and spring pre-loads to achieve desired firmness levels without manual intervention.
Solution Approach 2:
The mattress system incorporates feedback mechanisms through sensors that monitor user position, pressure distribution, and environmental conditions. This feedback is used by the control system to dynamically adjust firmness settings, ensuring optimal comfort and support for each user's specific needs.
3Object-affected harmful factors
If traditional mattresses are used, then the structure is simple, but moisture accumulates leading to mold and mite contamination
Solution Approach 1:
The mattress incorporates continuous air circulation and moisture management functions. Fans and air channels operate continuously or periodically to maintain dry conditions, preventing moisture accumulation that would lead to mold and mite growth. This continuous action ensures long-term hygiene without requiring frequent manual intervention.
Solution Approach 2:
The mattress system integrates multiple functions including support, firmness adjustment, and moisture management into a single unified structure. The same actuator system that adjusts firmness also influences air circulation patterns, while integrated fans and heating elements provide comprehensive environmental control to prevent contamination.

AI summary
A bed includes a mattress set on which a user's body is placed, an adjustable bedframe to adjust a position or orientation of the mattress set for various sitting and sleeping positions, and a dryer to dry the mattress set. The dryer includes a fan, a filter, and a heater to discharge filtered hot air toward the dryer to reduce mildew and mites. A humidity sensing sheet may be provided to sense a humidity level at different regions or areas of the bed, and the dryer may be controlled to supply hot air to regions of the bed having a higher humidity level than a predetermined humidity level or humidity range.
