Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing duvet systems fail to provide effective temperature regulation for fluctuating room temperatures and varying user comfort needs, requiring multiple duvets and incurring storage and cost inefficiencies, while existing solutions do not adequately address these issues.
Innovation Solution
A duvet system with integrated temperature, humidity, and motion sensors, inflatable air chambers, and a control unit to adjust thermal insulation by pumping or releasing air, allowing for dynamic temperature regulation based on ambient and vital parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple duvets (summer and winter) are used for temperature regulation, then temperature control capability is improved, but device complexity and storage requirements increase
Solution Approach 1:
The patent implements dynamic temperature regulation by making the duvet's thermal insulation properties adjustable in real-time. The duvet transitions from a static structure to a dynamic system where air chambers can be inflated or deflated on demand, allowing the user to adapt the duvet's insulation level to match changing ambient temperatures and personal comfort needs throughout the year.
Solution Approach 2:
The patent creates a universal duvet system that can serve multiple seasonal needs with a single device. By incorporating adjustable air chambers that modify thermal insulation, the same duvet can provide light insulation for warm summer nights or heavy insulation for cold winter mornings, replacing the need for separate summer and winter duvets.
2Adaptability or versatility
If multiple duvets are used for different seasons, then temperature adaptability is improved, but storage space and cost increase
Solution Approach 1:
The patent creates a universal duvet system that can serve multiple seasonal needs with a single device. By incorporating adjustable air chambers that modify thermal insulation, the same duvet can provide light insulation for warm summer nights or heavy insulation for cold winter mornings, replacing the need for separate summer and winter duvets.
Solution Approach 2:
The system allows users to discard excess insulation by deflating air chambers when not needed, and recover insulation by inflating them when required. This on-demand adjustment eliminates the need to permanently maintain multiple duvets for different seasons, reducing storage requirements and overall quantity of textile materials needed.
3Ease of manufacture
If traditional passive duvet design is used, then manufacturing simplicity is maintained, but temperature regulation effectiveness deteriorates
Solution Approach 1:
The patent introduces pneumatic elements (air chambers) into the duvet structure, allowing control of thermal insulation through air pressure and volume adjustments. This approach maintains relative manufacturing simplicity by using basic pneumatic components while dramatically improving temperature regulation effectiveness through active control of the insulation layer.
Solution Approach 2:
The system incorporates temperature sensors that continuously monitor the sleeping environment and provide feedback to a control unit. Based on this feedback, the system automatically adjusts the air chamber inflation level to maintain optimal temperature, transforming the passive duvet into an active temperature regulation system that responds dynamically to environmental changes.
4Difficulty of detecting and measuring
If external sleep tracking devices are used, then vital parameter monitoring is achieved, but device complexity and cost increase
Solution Approach 1:
The patent merges the functions of the duvet with sleep tracking capabilities by integrating sensors directly into the duvet structure. Temperature, humidity, and acceleration sensors are incorporated into the duvet layers, combining the sleeping cover function with health monitoring function into a single integrated system, eliminating the need for separate wearable or external tracking devices.
Solution Approach 2:
The duvet performs self-monitoring of sleep parameters through its integrated sensors, automatically detecting temperature, humidity, and movement without requiring external assistance. The system serves its own monitoring function, eliminating the need for users to wear separate tracking devices or set up external equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables cost-effective, energy-efficient temperature control without additional duvets, maintaining optimal sleeping temperature through scalable and comfortable operation, reducing the need for external sleep tracking devices.
Implementation Method 1
The layer of textile, inflatable air chambers serves as a heat-regulating air insulation layer. The more air there is in the air chambers, the greater the thermal insulation.
Implementation Method 2
The less air there is in the air chambers, the lower the thermal insulation.
