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
1Strength
If coil springs are complicatedly entangled to form a single cushion member, then the mattress provides cushioning support, but vibrations from one spring are easily transmitted to another spring causing discomfort
Solution Approach 1:
The mattress is divided into multiple independent spring modules arranged in a pocket configuration rather than a single entangled spring system. Each module operates independently, preventing vibration transmission between adjacent springs while maintaining cushioning support functionality.
2Ease of manufacture
If a conventional spring mattress is used, then the structure is simple and manufacturing is easy, but the firmness cannot be adjusted for different users
Solution Approach 1:
The mattress incorporates adjustable firmness mechanisms that allow the support characteristics to be dynamically changed according to different user needs. The spring modules can be configured or adjusted to provide different firmness levels, enabling the same mattress to adapt to multiple users with different preferences.
3Ease of operation
If the mattress surface is in direct contact with the user, then comfort is provided, but sweat and bodily fluids permeate the surface causing moisture accumulation
Solution Approach 1:
The mattress incorporates porous or breathable materials in its construction that allow moisture vapor to pass through while maintaining comfort contact with the user. This prevents sweat and bodily fluids from accumulating on the mattress surface, reducing the risk of mold and mite contamination while preserving user comfort.

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.
