Tiny House Assembly With Narrow CLT Panels and Hidden Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing tiny houses using Cross-Laminated Timber (CLT) panels result in high material consumption, transportation costs, and require skilled labor, while also exposing visible brackets and lacking in aesthetic appeal and structural strength, especially in the face of natural disasters.
Innovation Solution
A method and assembly kit for connecting narrow building panels, preferably CLT, using tongue and groove formations with concealed attachment screws, allowing for easy assembly and improved structural integrity without visible brackets, utilizing predrilled channels for screw attachment in staggered patterns to enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large CLT panels are used for construction, then construction speed is improved, but material consumption increases and transportation costs increase
Solution Approach 1:
The patent divides large CLT panels into multiple narrow strips (e.g., 5-10 cm width) that can be efficiently transported and stored. These segmented strips are then reassembled on-site using tongue-and-groove connections to form wall panels of any required size, eliminating the need to transport and store large bulky panels while reducing material waste from cutting operations.
2Productivity
If large CLT panels are used for construction, then construction speed is improved, but transportation costs increase
Solution Approach 1:
The patent segments large panels into narrow strips that fit efficiently into standard transportation containers, maximizing container utilization and reducing the number of trips required. The strips can be stacked and arranged optimally during transport, significantly reducing the volume occupied compared to transporting equivalent area of large panels with all their cutout waste.
3Strength
If various connection methods are used to connect panels, then structural strength is improved, but visible brackets remain and aesthetic appeal deteriorates
Solution Approach 1:
The patent extracts and removes all visible metal connection elements (brackets, screws, nails) from the exterior surface of the wall panels. Instead, it uses concealed tongue-and-groove mechanical interlocking combined with adhesive bonding, where the connection elements are hidden within the panel thickness or covered by the panel surfaces themselves, maintaining both structural integrity and aesthetic appearance.
Solution Approach 2:
The patent applies different connection qualities at different locations: the tongue-and-groove mechanical interlocking provides strong structural connection at the joint interface, while the exterior surfaces maintain uniform panel appearance without visible fasteners or brackets. The connection mechanism is localized within the groove geometry rather than being exposed on the surface.
4Ease of operation
If narrow building panels are connected using traditional methods, then assembly is simplified, but structural strength against natural disasters deteriorates
Solution Approach 1:
The patent merges two connection mechanisms into a unified system: mechanical tongue-and-groove interlocking provides immediate structural rigidity and resistance to lateral forces from natural disasters, while adhesive bonding applied within the groove provides additional bonding strength and seals the joint. This combination maintains assembly simplicity while dramatically improving structural performance.
