Bedding Climate Control Using Forced Air for Rapid Heating and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bed temperature control methods, such as electric blankets, are limited in heating power, take a long time to raise temperature, provide no cooling, and lack fresh air circulation, posing safety risks and inefficiencies.
Innovation Solution
A bedding climate control apparatus that uses a quiet fan/blower with an oversized ceramic thermal element and air duct to deliver tempered or untempered air, controlled by a wireless remote or smartphone, providing adjustable heating and cooling with a flexible hose and retention unit to maintain consistent temperature and airflow.
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 time is long (30-45 minutes)
Solution Approach 1:
The patent replaces the resistive heating elements (mechanical/electrical system) of traditional electric blankets with a forced air heating system that uses a blower motor to circulate heated air through the bedding. This substitution enables much higher heating power delivery and significantly reduces heating time from 30-45 minutes to just a few minutes, while also providing cooling capability through the same air circulation system.
2Adaptability or versatility
If electric blankets are used, then heating is provided, but no cooling function is available
Solution Approach 1:
The patent implements a multi-functional climate control system where a single forced air circulation system provides both heating and cooling functions. The same blower motor and air circulation mechanism that delivers heated air for warming the bedding can also deliver cool air for cooling, eliminating the need for separate heating and cooling devices and reducing overall system complexity despite the expanded functionality.
3Adaptability or versatility
If electric blankets are used, then heating is provided, but fresh air circulation is not available
Solution Approach 1:
The forced air circulation system serves multiple purposes simultaneously: it distributes heated or cooled air throughout the bedding, provides fresh air circulation to improve air quality, and enables both heating and cooling functions. This multi-functional approach adds air circulation capability without requiring a separate ventilation system, thereby avoiding increased complexity.
4Reliability
If electric blankets with embedded wires are used, then heating is provided, but safety risks exist from wire damage and fires
Solution Approach 1:
The patent eliminates the embedded wire heating elements that pose safety risks by replacing them with a forced air heating system. The heating function is achieved through air circulation rather than direct contact with electrical wires, removing the hazards of wire chewing by pets, wire damage by children, and fire risks from damaged wires, while maintaining effective heating capability.
5Object-affected harmful factors
If acoustic dampening is added to reduce fan noise, then noise level decreases, but device size increases
Solution Approach 1:
The patent incorporates acoustic dampening material within the housing during the manufacturing process, before the device is assembled and installed. This preliminary integration of noise reduction features allows for effective sound absorption without requiring additional external space, as the dampening material is built into the existing housing structure rather than added as a separate component.

Implementation Method 1
tempered (heated via a ceramic thermal element) air
Implementation Method 2
forced airflow from a fan/blower within a housing to selectively deliver tempered (heated via a ceramic thermal element) and untempered (room temperature) air through an air duct to bedding

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 foam 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 Bluetooth enabled device.
