Solution Overview

Problem

Existing bed dryers fail to effectively circulate air, leading to loss of air pressure on mattresses and inability to dry items in drawers, while also being costly and inefficient in preventing germ propagation.

Innovation Solution

A bed dryer system with modularized air blowing devices at the frame and drawers, featuring a first air blowing device for the mattress and a second for the drawer, allowing for controlled warm air circulation and modular fan and heater configurations to ensure efficient drying and germ prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a warm air/cold air device is installed to dry the mattress, then germ propagation is prevented, but air circulation is poor causing loss of air pressure

Engineering Contradiction:
Improvegerm prevention effectivenessVSAvoidair circulation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The air blowing device is divided into multiple independent blowing holes distributed across the mattress surface. Each blowing hole operates independently to supply warm air to different regions, improving overall air circulation efficiency while maintaining effective germ prevention coverage across the entire mattress area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the mattress receive warm air through locally distributed blowing holes. The system provides localized air supply tailored to specific areas, ensuring uniform air pressure distribution and effective germ prevention across different zones of the mattress without losing overall air pressure.

Inventive Principle:
Principle #3Local quality

2Reliability

If professional bed care companies are used for cleaning and sterilization, then thorough germ removal is achieved, but high costs are incurred

Engineering Contradiction:
Improvesterilization effectivenessVSAvoidoperational cost
Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The bed system includes an integrated air blowing device with heater that enables the mattress to dry and sterilize itself. By generating warm air internally and circulating it through the mattress via multiple blowing holes, the system achieves self-sterilization without requiring external professional services, significantly reducing operational costs while maintaining effective germ removal.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If air blowing devices are integrated into the frame and drawer, then drying coverage is improved, but device complexity increases

Engineering Contradiction:
Improvedrying coverageVSAvoidair blowing device configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The air blowing device integrates the heater and multiple adjustable blowing holes into a single unified component mounted on the frame. This merged design provides comprehensive drying coverage for both the mattress and drawer contents while minimizing the number of separate parts, thereby reducing overall device complexity despite the enhanced functionality.

Inventive Principle:
Principle #5Merging (Combining)
