Solution Overview
Problem
Existing construction modules require additional insulation steps post-assembly, leading to complexity, non-uniform insulation, and thermal bridge issues, necessitating further specialist interventions to meet thermal regulations.
Innovation Solution
A composite construction element with three superimposed layers, including a wood layer, a thermally insulating layer, and another wood layer, where spacers are filled with insulating material during prefabrication, ensuring uniform insulation and minimizing thermal bridges, and featuring assembly means for interlocking with other elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulation is performed after assembly by blowing insulation into cavities, then insulation can be added to the construction, but insulation uniformity cannot be guaranteed and thermal bridges remain at rod junctions
Solution Approach 1:
The patent applies preliminary action by integrating insulation material into the construction elements during the prefabrication process, before assembly. The insulation material is placed in cavities and covered with additional insulation layers during manufacturing, ensuring uniform insulation distribution and eliminating the need for post-assembly insulation operations.
Solution Approach 2:
The patent uses composite materials by combining structural wood components with insulation materials in a single integrated construction element. The wood elements provide structural support while the insulation material fills cavities and covers surfaces, creating a composite structure that simultaneously provides both mechanical strength and thermal insulation properties.
2Reliability
If additional insulation steps are required after assembly to meet thermal regulations, then thermal insulation can be improved, but the construction process becomes more complex and requires specialist companies
Solution Approach 1:
The patent applies preliminary action by integrating insulation material into the construction elements during the prefabrication process, before assembly. The insulation material is placed in cavities and covered with additional insulation layers during manufacturing, ensuring uniform insulation distribution and eliminating the need for post-assembly insulation operations.
Solution Approach 2:
The construction elements are designed to be self-insulating through integrated insulation layers and cavity filling during prefabrication. The elements arrive at the construction site ready-to-assemble with complete insulation, allowing unskilled workers to assemble them without requiring specialist insulation companies or additional insulation steps.
3Strength
If spacers are made of wood only, then structural strength is maintained, but thermal bridges are generated at junctions between plates and module core
Solution Approach 1:
The patent uses composite materials by combining structural wood components with insulation materials in a single integrated construction element. The wood elements provide structural support while the insulation material fills cavities and covers surfaces, creating a composite structure that simultaneously provides both mechanical strength and thermal insulation properties.
Solution Approach 2:
The patent introduces an intermediary insulation layer between wooden spacers and wooden plates at their junctions. This intermediary insulation material acts as a thermal break, preventing direct thermal conduction between the wood components while maintaining the structural connection, thereby eliminating thermal bridges at critical junction points.
4Adaptability or versatility
If reception spaces are left open for post-assembly insulation, then flexibility is maintained, but insulation material is exposed to weather and insulation uniformity cannot be ensured
Solution Approach 1:
The patent applies preliminary action by integrating insulation material into the construction elements during the prefabrication process, before assembly. The insulation material is placed in cavities and covered with additional insulation layers during manufacturing, ensuring uniform insulation distribution and eliminating the need for post-assembly insulation operations.
Solution Approach 2:
The patent uses covering layers (such as insulation boards or protective films) to seal the reception spaces during prefabrication. These flexible covers enclose the insulation material, protecting it from weather exposure while allowing the element to be manufactured and assembled. The covers are integrated into the element design and do not compromise the insulation performance.
