Solution Overview

Problem

The existing methods for installing a light shaft in a thermally insulated basement wall are costly, complex, and create thermal bridges due to direct attachment to the building wall, making it difficult to locate pre-drilled holes and requiring time-consuming plastering.

Innovation Solution

A system where the light shaft is attached to thermal insulation with pre-marked or pre-drilled attachment points, allowing the insulation to be glued or fastened to the wall first, and then the light shaft can be mounted without drilling into the wall, using self-tapping dowels that connect with the insulation material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pre-drilled holes are made in the building wall to attach the light shaft, then the light shaft can be securely attached, but it becomes extremely difficult to locate the holes after thermal insulation is installed

Engineering Contradiction:
Improveattachment reliabilityVSAvoidhole location detectability
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces the thermal insulation board as an intermediary carrier that incorporates attachment points directly into its structure. The light shaft is attached to the insulation board rather than directly to the building wall, and the attachment points are accessible on the outer surface of the insulation board, making them easily locatable without drilling through the insulation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the light shaft is attached directly to the building wall, then secure attachment is achieved, but thermal bridges are created that reduce insulation effectiveness

Engineering Contradiction:
Improveattachment securityVSAvoidthermal energy loss
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The thermal insulation board serves as a mediator between the building wall and the light shaft. The attachment points are created within the insulation board material itself (through melting, punching, or adhesive bonding), allowing the light shaft to be securely attached without penetrating the insulation layer or creating direct thermal bridges to the building wall.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple pieces of insulation are used to piece together around the light shaft, then the light shaft can be installed, but the insulation arrangement becomes extremely complex

Engineering Contradiction:
Improvelight shaft installation capabilityVSAvoidinsulation arrangement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of adapting the insulation to fit around the light shaft (complex piecing together), the patent inverts the approach by first creating attachment points within the insulation board, then attaching the light shaft to these pre-positioned points. This allows the insulation to be installed as complete panels without complex cutting and assembly.

Inventive Principle:
Principle #13The other way round (Inversion)

4Reliability

If fastenings are used to attach the light shaft to the building wall, then attachment is achieved, but subsequent plastering becomes very time-consuming

Engineering Contradiction:
Improveattachment strengthVSAvoidplastering time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The insulation board with its integrated attachment points serves as a ready-made mounting structure. The attachment points are designed to provide secure mechanical attachment (through melted recesses, punched holes with deformation, or adhesive bonding) while maintaining a smooth outer surface that eliminates the need for additional plastering work around fastening locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The insulation unit has an insulation component (4), which is arranged on a building wall (1) made of fresh concrete. The insulation component comprises attachment points (4.1), and a light well is attached to the attachment points. The insulation component is bonded to the building wall and consists of an insulation material (4.3) and a lamination (4.2). A fastening unit i.e. self-cutting anchor bolt, is partially arranged in the attachment points. The light well is arranged at the insulation component by the attachment points. : An independent claim is also included for a method for mounting a light well at a housing wall. USE : Heat insulation unit for use at a light well for a building wall at a basement area of a house. ADVANTAGE : The insulation component is arranged on the building wall, thus fastening the insulation component at a basement wall in a form-fit or force-fit manner, and hence mounting the light well at the basement wall in a simple manner. DESCRIPTION OF DRAWINGS : The drawing shows schematic sectional views of a heat insulation unit. 1 : Building wall 4 : Insulation component 4.1 : Attachment points 4.2 : Lamination 4.3 : Insulation material.
