Solution Overview

Problem

Existing bed systems lack efficient and customizable solutions for delivering temperature-controlled air, often requiring the entire mattress to be cooled or heated, which can be inefficient and uncomfortable, especially for shared beds where users may have different temperature preferences.

Innovation Solution

An air system comprising a distribution manifold, layer assembly, and hose assembly that directs air flow through a spacer layer and cover, with flaps and connectors to secure the system on a mattress, allowing for independent temperature control for each user and improved airflow, using a D-shaped hose to prevent kinking and a stitching pattern to direct air effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the entire mattress is cooled or heated, then temperature control is provided, but energy consumption increases and comfort decreases for shared beds with different temperature preferences

Engineering Contradiction:
Improvetemperature controlVSAvoidenergy consumption
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The mattress is divided into multiple independently controllable zones (first zone, second zone, third zone, fourth zone) with separate air delivery systems for each zone. This allows temperature control to be applied only to specific areas where needed, rather than cooling or heating the entire mattress, thereby reducing energy consumption while maintaining temperature control functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different zones of the mattress are provided with different temperature characteristics through independent air delivery systems. Each zone can be customized to have different thermal properties based on local user preferences, allowing one side of the bed to be cooler while the other side remains warmer, thus avoiding the energy waste of conditioning the entire mattress uniformly.

Inventive Principle:
Principle #3Local quality

2Temperature

If the entire mattress is cooled or heated, then temperature control is provided, but comfort decreases when users have different temperature preferences

Engineering Contradiction:
Improvetemperature controlVSAvoiduser comfort
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The mattress is segmented into multiple independently controllable zones that can be adjusted according to each user's preferences. This allows different temperature settings on different sides of the bed, accommodating users with different thermal preferences simultaneously and thereby improving overall user comfort.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each zone of the mattress can be customized with different temperature characteristics to match local user preferences. This personalized approach ensures that each user experiences optimal comfort in their preferred sleeping area without being affected by temperature settings in other zones.

Inventive Principle:
Principle #3Local quality

3Device complexity

If air flow is restricted, then system simplicity is maintained, but air delivery efficiency decreases

Engineering Contradiction:
Improvesystem simplicityVSAvoidair delivery efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The air delivery system incorporates adjustable air flow controllers that allow dynamic regulation of air flow rates to each zone. This dynamic control capability enables the system to optimize air delivery efficiency by adjusting flow rates based on actual cooling or heating requirements, while maintaining relatively simple system architecture through the use of basic valve mechanisms rather than complex control systems.

Inventive Principle:
Principle #15Dynamics
