Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In timber frame building construction, traditional methods require skilled labor and significant time to construct separating walls, and the use of metal strips compromises acoustic and vibration insulation, especially when on-site assembly is necessary.
Innovation Solution
A single piece building component with timber studs and acoustic connectors located on the inner edge of the studs, eliminating the need for metal strips and allowing for pre-assembled, easily installable separating walls with guaranteed separation and improved sound insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional on-site construction with metal strips is used to tie timber frame leafs together, then the frames can be structurally connected, but acoustic and vibration insulation performance deteriorates due to sound transmission paths through the metal strips
Solution Approach 1:
The patent removes metal strips entirely from the construction system and replaces them with acoustic connectors made of timber that incorporate sound-absorbing material. This extraction eliminates the harmful sound transmission path while maintaining structural connection through alternative means.
Solution Approach 2:
The acoustic connector acts as an intermediary element between timber frame leafs. It provides structural connection through its timber components while the integrated sound-absorbing material mediates against sound transmission, preventing the harmful effect of direct metal-to-timber sound paths.
2Productivity
If pre-assembled wall leafs are brought to site to speed up construction, then construction time is reduced, but maintaining precise separation between leafs becomes difficult compromising acoustic performance
Solution Approach 1:
The patent merges two separate wall leafs with the acoustic connector into a single pre-assembled unit. The acoustic connector is integrated between the leafs during manufacturing, ensuring precise separation is built-in rather than relying on on-site adjustment. This combined unit maintains acoustic performance while enabling rapid installation.
Solution Approach 2:
The acoustic connector and separation distance are predetermined and built into the pre-assembled unit during manufacturing. This preliminary action ensures precise separation is achieved without requiring skilled on-site adjustment, maintaining acoustic performance while speeding up construction.
3Stability of the object's composition
If multiple metal strips are used to tie frames together to meet regulatory requirements, then structural stability is improved, but the number of sound transmission paths increases deteriorating acoustic performance
Solution Approach 1:
The patent extracts metal strips from the system entirely and replaces them with timber-based acoustic connectors. This eliminates the material that creates sound transmission paths while maintaining frame stability through the timber connector's structural properties.
Solution Approach 2:
The patent changes the material parameter from metal to timber with integrated sound-absorbing material. This parameter change transforms the connector from a sound transmission path to a sound-absorbing element, maintaining stability while reducing harmful acoustic transmission.

AI summary
A single leaf building component for use in separating walls in timber frame building construction. Two timber frame studs are held together at an edge by at least one acoustic connector. The connector holds the frames at a fixed distance, prevents sound transfer and provides a lifting point. Embodiments of the connector are described with the inclusion of a dampening material and having a timber body.
