Prefabricated Wooden Elements with Integrated Functional Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current prefabricated wooden building elements often require extensive on-site processing and post-processing, leading to inefficiencies and incomplete surfaces due to the lack of integrated functional recesses that can accommodate various functions such as insulation, ventilation, and fire protection, which are not addressed in existing manufacturing processes.
Innovation Solution
The development of prefabricated building elements with integrated functional recesses that are not relevant to connections, allowing for the incorporation of features like thermal insulation, active fire protection, ventilation systems, and lighting during production, thereby simplifying construction and ensuring flawless surfaces without on-site modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional gluing methods with synthetic resins are used to produce layered wooden building elements, then manufacturing strength and connection reliability are improved, but environmental harm and indoor climate quality deteriorate due to chemical outgassing and odors
Solution Approach 1:
The invention extracts and eliminates the harmful adhesive substance from the construction system. Instead of using synthetic resin adhesives that cause outgassing and odors, the patent employs mechanical connection elements (dowels, nails, or screws) that physically join the wood layers without requiring chemical bonding agents, thereby removing the source of harmful emissions while maintaining structural integrity
Solution Approach 2:
The wood layers themselves provide the bonding function through mechanical interlocking with connection elements. The structure serves its own joining function without external chemical adhesives, using the natural properties of wood and mechanical fasteners to achieve reliable layer connection while avoiding harmful substances
2Adaptability or versatility
If extensive on-site processing is performed to add functional recesses for insulation and ventilation, then functional versatility is improved, but construction time and labor costs worsen
Solution Approach 1:
The invention performs preliminary action by manufacturing the building elements with all necessary functional recesses, channels, and openings for insulation, ventilation, and fire protection already integrated during factory production. This advance preparation eliminates the need for time-consuming on-site modifications, as the elements arrive ready for immediate assembly with all functional features pre-configured
Solution Approach 2:
The invention merges multiple functions (structural support, thermal insulation, ventilation, fire protection) into a single integrated building element. By combining these previously separate components into one prefabricated unit with integrated recesses and channels, the system reduces the number of separate installation steps and accelerates construction while maintaining full functional versatility
3Object-generated harmful factors
If layered construction without glue is used to improve environmental performance, then environmental harm is reduced, but manufacturing precision and connection reliability worsen
Solution Approach 1:
The invention replaces the chemical bonding system (adhesives) with a mechanical bonding system (dowels, nails, or screws). This substitution maintains connection precision and reliability through controlled mechanical fastening while eliminating chemical emissions. The mechanical connection elements provide precise positioning and secure joining without requiring adhesive application and curing processes

AI summary
The element has two layers (4, 5) connected with each other in a fixed manner. One of the layers (5) has a functional recess (15) on a side, which faces the other layer (4). The recess lies at a distance to one of both laminar outer sides (2, 3). The recess is provided free from a connection function between the layers. The recess is designed in type of a channel, container and passage, and the layers are designed as massive wood layers. The recess is provided with a light unit i.e. LED light unit, for direct or indirect illumination of the recess. An independent claim is also included for a method for manufacturing a prefabricated construction element.
