Forced-Air Bedding Climate Control for Rapid Heating and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bed temperature control methods, such as electric blankets and medical forced air bed heating systems, are limited in heating power, inefficient, unsafe, and lack cooling capabilities, with issues like wire damage, reliability concerns, and inability to provide even heating or cooling without proprietary gowns or sheets.
Innovation Solution
A bedding climate control apparatus that uses forced air, heated by a ceramic thermal element, to adjust temperature and humidity between bed sheets, controlled via wireless commands, with a fan/blower system designed for quiet operation and adjustable airflow, and a flexible hose for efficient air delivery, allowing for remote control and safe heating/cooling of bedding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electric blankets are used for bed heating, then heating function is provided, but heating power is limited and heating speed is slow (30-45 minutes to raise temperature by 20 degrees F)
Solution Approach 1:
The patent replaces the electrical resistance heating mechanism of electric blankets with a forced air heating system using a blower and heating element. This substitution allows for much higher power output and faster heating speeds while eliminating the limitations of embedded wire heating elements.
Solution Approach 2:
The invention uses forced air circulation through a blower system to distribute heat rapidly throughout the bedding. The pneumatic delivery of heated air enables fast heating response and high power transfer to the bedding materials, overcoming the slow thermal conduction of electric blanket wires.
2Reliability
If electric blankets with embedded wires are used, then heating function is provided, but wires can be damaged by pets, children, or sharp objects creating safety hazards
Solution Approach 1:
The patent extracts the vulnerable embedded wire heating elements from the bedding system and replaces them with an external forced air heating system. The heating function is maintained while the harmful exposed wires are completely removed, eliminating the safety hazards associated with wire damage.
Solution Approach 2:
The invention introduces forced air as an intermediary medium to transfer heat to the bedding, replacing direct contact with electrical wires. This intermediary approach maintains heating effectiveness while eliminating the direct safety risks of exposed electrical elements that can be chewed or damaged.
3Productivity
If medical forced air bed heating systems are used, then rapid heating is achieved, but proprietary gowns with airflow channels or perforated sheets are required
Solution Approach 1:
The patent creates a universal forced air heating system that works with standard bedding materials rather than requiring proprietary gowns or specialized perforated sheets. The system uses common materials like comforters and sheets, making the technology accessible and eliminating the need for specialized medical equipment.
Solution Approach 2:
The invention changes the physical parameters of the bedding environment by introducing forced air circulation, which enables rapid heating through convection rather than requiring specialized conductive materials. This parameter change allows standard bedding to function effectively with the heating system.
4Power
If electric blankets are used, then heating function is provided, but no cooling function is available
Solution Approach 1:
The patent implements a dynamic system where the blower can operate in multiple modes: heating mode with the heating element activated, cooling mode with only the blower running to circulate ambient air, and off mode. This dynamic operation provides both heating and cooling capabilities from a single system.
Solution Approach 2:
The forced air system serves multiple functions: it can heat the bedding using the heating element, cool the bedding by circulating cooler ambient air, and provide air circulation independently. This multi-functionality replaces the single-function electric blanket with a versatile climate control system.

AI summary
A bedding climate control apparatus that delivers, in a quiet manner, forced airflow from a fan/blower within a housing to selectively deliver tempered (heated via a thermal element) and untempered (room temperature) air through a flexible hose to bedding. The quiet manner is attained with acoustic dampening material in the path of incoming airflow to the fan/blower and by oversizing each of the components that create a pressure drop including the capacity of the fan/blower over what is needed to deliver a required amount of airflow. Temperature may be set remotely via a wireless remote control and via a protocol access enabled device.
