Solution Overview
Problem
Current bed systems lack effective microclimate control, leading to discomfort due to temperature and humidity fluctuations, which can disrupt sleep quality.
Innovation Solution
A bed system with a microclimate control subsystem that includes airflow pads and a fan assembly to condition air, providing heated or cooled air to the mattress, and a thermal module with temperature sensors for closed-loop control, ensuring precise temperature management and humidity regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heating and cooling systems are used in beds, then temperature control is provided, but microclimate control precision is insufficient leading to discomfort
Solution Approach 1:
The bed system is divided into multiple independent climate control zones (head zone, middle zone, foot zone) that can be controlled separately. Each zone has its own airflow pads and temperature control, allowing precise microclimate management for different body regions simultaneously, resolving the contradiction between temperature precision and control effectiveness.
2Productivity
If airflow pads are integrated into the mattress structure, then air distribution is improved, but mattress structural complexity increases
Solution Approach 1:
The airflow pads are integrated directly into the mattress support structure, merging the air distribution function with the structural support function. This combination improves air distribution efficiency while avoiding the need for separate, complex air delivery mechanisms, thus resolving the contradiction between productivity and device complexity.
3Adaptability or versatility
If multiple airflow zones are created for different body regions, then comfort is improved, but system complexity increases
Solution Approach 1:
Different zones of the mattress (head, middle, foot) are equipped with different airflow pad configurations and control settings optimized for local requirements. The head zone may have higher airflow for cooling, while the foot zone has lower airflow, providing adaptability and versatility for different body regions without requiring a completely complex centralized control system.

AI summary
A bed system includes microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.
