Solution Overview

Problem

Conventional attic hatches often result in significant heat loss due to improper insulation and thermal bridging, as heat rises into the attic and escapes through the roof, leading to inefficient energy use.

Innovation Solution

An attic hatch system with hanger parts that include a top flange member, skirt, and base flange member to support the hatch within the attic access conduit, combined with a peripheral insulative collar and thermal breaks to minimize heat transfer, using materials with low thermal conductivity and a two-part expanding foam system to fill gaps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional attic hatches with peripheral flanges are used, then the hatch can be mounted in the ceiling, but significant heat loss occurs due to thermal bridging and improper insulation

Engineering Contradiction:

Improveheat lossVSAvoidinsulation effectiveness

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The patent introduces hanger parts as intermediary elements between the attic hatch and the ceiling structure. These hanger parts include thermal breaks that mediate the thermal connection, preventing direct thermal bridging through the ceiling joists while still providing structural support for the hatch assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The hanger parts are constructed using composite materials with different thermal conductivities. The structure combines materials that provide both structural strength and thermal resistance, creating a multi-layered system that supports the hatch while minimizing heat transfer through the assembly.

Inventive Principle:

Principle #40Composite materials

2Loss of energy

If the hatch panel supports insulative material directly, then insulation is provided, but thermal bridging occurs through the hatch structure

Engineering Contradiction:

Improveheat lossVSAvoidhatch structure

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The hatch assembly is segmented into distinct functional components: the hatch panel, insulative material layer, hanger parts, and ceiling mounting structure. This segmentation allows each component to be optimized independently for its specific function while reducing thermal bridging pathways between components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the hatch assembly have different thermal and structural properties tailored to their specific functions. The hanger parts have localized thermal breaks at critical junctions, while the hatch panel provides continuous insulation, creating a non-uniform but optimized thermal resistance distribution throughout the assembly.

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If simple mounting methods are used, then installation is easy, but proper thermal breaks and insulation cannot be achieved

Engineering Contradiction:

Improveinstallation simplicityVSAvoidheat loss

Core Design Contradiction:

Ease of manufactureVSLoss of energy

Solution Approach 1:

The hanger parts are pre-configured with integrated thermal breaks and insulation features during manufacturing. This preliminary preparation of thermal management components allows for simpler on-site installation while ensuring proper thermal performance is achieved without requiring complex field assembly procedures.

Inventive Principle:

Principle #10Preliminary action

AI summary

An attic hatch system for mounting within an attic access conduit defined by a ceiling, has an attic hatch structured to mount within the attic access conduit, the attic hatch comprising an insulative hatch body; one or more hanger parts structured to support the attic hatch within the attic access conduit in use, with each of the one or more hanger parts comprising: a top flange member extended laterally outward from the insulative hatch body to extend over and secure on a top shoulder of a structural member of the ceiling in use; a skirt structured to depend from the top flange member through the attic access conduit in use; and a base flange member extended laterally inward from the skirt to define a seat that supports a base surface of the attic hatch.
