Insulating Panel Tongue Groove Connection Load Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating panel systems with triangular tongue and groove connections are prone to damage under load, leading to compromised insulation and rainproofing, as the thin upper groove cheek is susceptible to damage from handling and environmental factors.
Innovation Solution
The tongue angle is made greater than the bevel angle, with a rectilinear portion that increases the thickness of the upper groove cheek, shifting the notch effect point away from the top side and enhancing the system's load resistance while maintaining rain safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tongue and groove connection is made with a triangular groove design, then the assembly speed and dimensional accuracy are improved, but the upper groove cheek becomes thin and susceptible to damage under load
Solution Approach 1:
The patent changes the geometric parameters of the tongue and groove connection by introducing a rectilinear portion with a specific tongue angle (greater than the bevel angle) instead of a purely triangular design. This parameter change increases the upper groove cheek thickness while maintaining the connection's assembly advantages
Solution Approach 2:
The patent adds a rectilinear portion that extends in a direction perpendicular to the bevel, creating a multi-dimensional geometry. This dimensional addition transforms the purely triangular cross-section into a composite shape with enhanced structural properties without compromising the tongue and groove connection functionality
2Reliability
If the tongue extends from the top of the board to maintain connection integrity, then the rainproofing is improved, but the thin upper groove cheek is easily damaged by loads
Solution Approach 1:
By changing the tongue geometry to include a rectilinear portion with a larger tongue angle, the patent simultaneously maintains the tongue's extension from the top of the board (preserving rainproofing) while increasing the upper groove cheek thickness (improving damage resistance)
3Strength
If thicker insulation boards are used to strengthen the connection, then the load resistance is improved, but the tongue must extend very long from the top which makes it susceptible to damage
Solution Approach 1:
The patent changes the tongue angle parameter to be greater than the bevel angle, which allows the tongue to achieve sufficient structural support with a shorter extension length from the top of the board, thereby reducing damage susceptibility while maintaining connection strength
Solution Approach 2:
By adding the rectilinear portion that extends in a different dimensional direction, the patent provides structural reinforcement without requiring the tongue to extend longer along the board thickness, thus avoiding increased damage susceptibility
