Solution Overview

Problem

Recessed lights in attics often have insulation accumulate on them, leading to heat trapping and potential damage due to the inability of existing solutions to effectively manage insulation distribution around these fixtures.

Innovation Solution

A transformable enclosure for recessed lights with sloped surfaces that deflect loose fill insulation, allowing heat to escape and preventing insulation accumulation, featuring a housing with a variable upward-facing surface and a bottom opening for easy installation and insulation placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If insulation is installed in the attic to a predetermined height, then thermal insulation performance is improved, but insulation material accumulates on recessed lights causing heat trapping and potential damage

Engineering Contradiction:

Improvethermal insulation performanceVSAvoidheat trapping and insulation accumulation

Core Design Contradiction:

Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The enclosure divides the attic space into two distinct zones: an insulated region above the recessed light and a non-insulated region around the light fixture. This segmentation allows insulation to be installed in the attic while preventing it from accumulating on the light, thereby maintaining thermal insulation performance without causing heat trapping damage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The enclosure acts as an intermediary barrier between the insulation material and the recessed light. It interfaces with the insulation material to deflect it away from the light fixture while allowing heat to escape through its thermally conductive properties, thus mediating between insulation installation and heat dissipation requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the enclosure is made transformable between flat and housing configurations, then ease of installation is improved, but device complexity increases

Engineering Contradiction:

Improveease of installationVSAvoidtransformable configuration mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The enclosure incorporates transformable elements that allow it to transition between a flat configuration for easy installation and a three-dimensional housing configuration for proper light enclosure. This dynamic adaptability simplifies the installation process while maintaining the necessary structural complexity to fulfill its protective and thermal functions.

AI summary

An enclosure for a recessed light in an attic is transformable between a first configuration in which the enclosure is flat and a second configuration in which the enclosure defines a housing. The housing has an opening at a bottom end for receiving the recessed light and an upwardly-facing surface opposite the opening. The upwardly-facing surface has a variable height relative to the bottom end.
