Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel assembly technologies require significant force and impact during assembly, making them difficult to assemble efficiently.
Innovation Solution
A mechanical locking device with a flexing groove extending from the transition between the locking strip surface and the panel edge at an angle, allowing the locking strip to flex during assembly, thereby reducing the required force and facilitating easier assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid locking strip is used in the mechanical locking device, then the locking strength and structural stability are improved, but the force and impact required for assembly increase significantly
Solution Approach 1:
The locking strip is designed with a flexing groove that allows it to dynamically change its shape during assembly. The groove enables the locking strip to flex and deform elastically when panels are being joined, reducing the peak force required for assembly. Once assembled, the locking strip returns to its original rigid shape, maintaining strong locking capability.
Solution Approach 2:
The stiffness parameter of the locking strip is made variable through the flexing groove design. During assembly, the groove allows the locking strip to exhibit lower effective stiffness, requiring less assembly force. After assembly, the locking strip maintains its high stiffness for secure locking. This parameter change resolves the contradiction between assembly ease and locking strength.
2Reliability
If a rigid locking strip is used in the mechanical locking device, then the structural stability and locking reliability are improved, but the ease of assembly deteriorates due to high impact requirements
Solution Approach 1:
The locking strip transitions from a static rigid structure to a dynamic structure with flexing capability. The flexing groove allows the locking strip to adapt its rigidity during the assembly process, making installation easier while maintaining reliable locking performance once assembled.
Solution Approach 2:
The flexing groove acts as a built-in cushioning element that absorbs assembly impacts and forces. By designing this flexibility feature beforehand, the system prevents damage during assembly while ensuring reliable locking, eliminating the need for external cushioning mechanisms.
3Ease of operation
If the locking strip is made more flexible to reduce assembly force, then the ease of assembly is improved, but the locking strength and structural stability may be compromised
Solution Approach 1:
The locking strip is segmented by the flexing groove, creating distinct zones: a flexible zone at the groove location and rigid zones in the main body. This segmentation allows the strip to flex only where needed during assembly while maintaining overall structural integrity and locking strength in the non-groove portions.
Solution Approach 2:
The flexing groove introduces localized flexibility only at the specific location where it is needed for assembly, while the rest of the locking strip maintains its full rigidity and strength. This local quality change ensures that the overall locking capability is not compromised while enabling easier assembly.

AI summary
A set of panels includes first and second panels and a mechanical locking device for assembly by vertical relative displacement of the panels. A locking strip extends from a first edge of the first panel in a direction parallel to first and second panel surfaces of the first panel. The locking strip includes a locking strip edge, and first and second locking strip surfaces respectively extending in directions substantially corresponding to those of the first and second panel surfaces. A locking element of the locking strip cooperates with a locking groove at the second edge of the second panel for locking in a direction parallel to the first panel surface. Opposite edges respectively include cooperating tongue and tongue groove for vertical locking. A flexing groove extends from a first locking strip surface/first edge transition and into the first panel at an angle α from the first panel surface.
