Solution Overview

Problem

Current large-scale environmental control systems, such as HVAC, cannot provide personalized thermal comfort within a bed, leaving users dependent on ambient conditions for sleep comfort.

Innovation Solution

An air distribution pad system placed on a mattress, comprising an upper and lower layer with a spacer material, and an air distributor that directs heated or cooled air from an engine through channels to provide personalized heating or cooling to a user's personal space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If large-scale environmental control systems (HVAC) are used to control ambient temperature, then building-wide thermal comfort is improved, but personalized thermal comfort within the bed cannot be provided

Engineering Contradiction:
Improvepersonalized thermal comfort controlVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mattress is divided into multiple independent air channels that can be individually controlled. Each channel receives conditioned air through separate pathways, allowing different zones of the mattress to be heated or cooled independently, thus providing personalized thermal comfort for different body regions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the mattress are provided with different thermal characteristics through the channel system. The air distribution pad creates localized temperature zones that match the user's personal comfort requirements, rather than applying uniform temperature control across the entire mattress surface.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If air channels are added to the mattress structure to enable personalized climate control, then personalized thermal comfort is improved, but the complexity of the mattress structure increases

Engineering Contradiction:
Improvepersonalized climate controlVSAvoidmattress structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The air distribution pad serves multiple functions simultaneously: it provides structural support as a mattress layer, creates air channels for climate control, and distributes conditioned air through its integrated channel system. This multi-functionality reduces the need for separate components and simplifies the overall system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The air channels are integrated within the layers of the mattress structure itself, with channels formed between the first and second layers. This nesting approach embeds the climate control functionality within the existing mattress architecture rather than adding separate external components.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If multiple air channels are formed through the mattress layers, then air distribution and personalized comfort are improved, but manufacturing complexity increases

Engineering Contradiction:
Improveair distribution efficiencyVSAvoidmanufacturing complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The air channels utilize pneumatic principles to distribute conditioned air throughout the mattress structure. The channels are designed to work with air pressure differentials, allowing efficient air flow distribution without requiring complex mechanical pumps or valves, thereby simplifying manufacturing while maintaining high air distribution efficiency.

Inventive Principle:
Principle #29Pneumatics and hydraulics

AI summary

An air distribution pad (12) comprises an upper layer (34), a lower layer (36), and a spacer material (32) located between the upper layer and the lower layer, the spacer material configured to allow air to pass therethrough. An air distributor (38) is configured to distribute air to the spacer material, wherein the air distributor comprises a port (40) configured to receive an air hose (16), wherein the port is directed laterally sideways from the air distributor. At least one joining structure (44) is coupled to the upper layer and the lower layer, the at least one joining structure providing one or more channels (46) formed through the spacer material in fluid communication with the air distributor. The one or more channels are configured to direct generally laterally flowing air from the port of the air distributor to a generally longitudinal direction along the at least one channel.
