Interlocking Connector With Trapezoid Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for joining surfaces, such as adhesives and nails, face challenges in ease of removability, speed of construction, and steadfastness, as they often leave residue or holes, take time to dry, and allow surfaces to slide or bend.
Innovation Solution
A system using trapezoid profile protrusions and slots on two surfaces, with a connector having parallel slots that interlock with the protrusions, allowing for easy alignment and secure joining while minimizing gaps and facilitating removal by sliding parallel to the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesives are used to join surfaces, then the surfaces are strongly joined, but the joining process takes a long time to dry and requires additional tools like vice grips
Solution Approach 1:
The patent replaces chemical bonding (adhesives) with a mechanical interlocking system consisting of protrusions and slots. The protrusion on one surface fits into the slot on another surface, creating a strong mechanical connection that provides immediate strength without requiring drying time or additional clamping tools.
2Strength
If adhesives or nails are used to join surfaces, then the surfaces are strongly joined, but removal is difficult and leaves residue or holes
Solution Approach 1:
The connector is designed as a segmented system with separate protrusion and slot components that can be easily separated. The protrusion fits into the slot to create a strong connection during use, but can be cleanly removed without leaving residue or holes, allowing for easy repair and reconfiguration.
3Strength
If traditional interconnecting joints like tongue and groove are used, then the joint is strong, but the surfaces can still slide and bend
Solution Approach 1:
The connector uses an asymmetric trapezoidal profile where the protrusion has a specific angled geometry that fits into a corresponding slot. This asymmetric design prevents sliding and bending by creating a geometric lock that resists movement in multiple directions while maintaining structural strength.

AI summary
A system and method for removably joining two surfaces together with a connector using protrusions and slots. A protrusion rising from the surface is slid into a slot in a parallel direction to the surface so it is secured against being removed in a perpendicular direction to the surface. Various shapes of protrusions and slots are possible, including trapezoid profiles.
