Solution Overview
Problem
Existing panel assembly methods require tools and do not facilitate a tight fit between panels, lacking efficient tool-free mounting solutions.
Innovation Solution
A mechanical connection arrangement using misaligned rod-shaped elements and insertion recesses with angles differing by 0.5° to 6°, allowing for elastic and plastic deformation upon assembly to achieve a secure, tool-free connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional tool-based assembly methods are used, then connection strength can be achieved, but assembly complexity and time consumption increase
Solution Approach 1:
The rod-shaped element and insertion recess are designed to automatically lock together through their geometric configuration without requiring external tools. The misalignment angle creates a self-locking mechanism where the rod deforms elastically to engage with the recess, achieving self-service assembly
Solution Approach 2:
The patent replaces traditional mechanical fastening systems (screws, bolts, clips requiring tools) with a purely geometric elastic deformation system. The connection is achieved through the elastic deformation of the rod-shaped element as it engages with the misaligned insertion recess, eliminating the need for mechanical assembly tools
2Strength
If panels are connected with parallel surfaces, then a tight fit is achieved, but the connection strength may be insufficient without additional locking mechanisms
Solution Approach 1:
The patent changes the angular parameter of the rod-shaped element and insertion recess from the conventional 0-degree alignment to a misaligned configuration (0.5° to 6° difference). This parameter change creates both the tight fit between parallel panel surfaces and the self-locking connection strength through elastic deformation, eliminating the need for additional locking mechanisms

AI summary
A mechanical connection arrangement for panels (1, 2), comprises a first panel (1), a second panel (2) and a mechanical locking device for locking the first panel (1) to the second panel (2). A surface of the first panel (1) and a surface of the second panel (2) are parallel and in contact in a locked position of the first and second panels (1, 2). The mechanical locking device comprises at least one rod-shaped element (3) at said surface of the first panel (1) and at least one corresponding insertion recess (4) at said surface of the second panel (2). The rod-shaped element (3) is configured to be inserted in the insertion recess (4). The lateral surface of the rod-shaped element (3) extends at a first angle (α) from the surface of the first panel (1) and the lateral side of the insertion recess (4) extends into the second panel (2) at a second angle (β) from the surface of the second panel (2). The difference between the first angle (α) and the second angle (β) is between 0.5 and 6, 2 and 4, or about 3 in an unlocked position of the first and second panels (1, 2). The rod-shaped element (3) and the insertion recess (4) are configured such that the difference between the first angle (α) and the second angle (β) is smaller in the locked position compared to when in the unlocked position.
