Building Panel Locking Tongue for Easy Snap-Release Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical locking systems for furniture components require precise alignment and insertion of a rod-shaped stick to disassemble, making the process cumbersome and prone to errors.
Innovation Solution
A mechanical locking system featuring a flexible tongue with a guiding protrusion that automatically guides a rod-shaped tool into the tongue groove, allowing for easy and precise disassembly without requiring precise orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rod-shaped stick is used to disassemble the locking system, then the locking connection can be released, but the disassembly process becomes cumbersome and error-prone due to the need for precise alignment and insertion
Solution Approach 1:
The guiding protrusion acts as an intermediary element between the rod-shaped tool and the tongue groove. It mediates the interaction by automatically guiding the tool into the correct position, eliminating the need for precise manual alignment while maintaining the reliability of the locking connection
Solution Approach 2:
The locking system performs self-alignment during disassembly. The guiding protrusion on the flexible tongue automatically guides the rod-shaped tool into the tongue groove without external assistance or precise positioning, making the disassembly process self-servicing and error-proof
2Strength
If the flexible tongue is designed to lock panels securely, then the locking strength is improved, but the disassembly becomes more difficult requiring precise orientation of the tool
Solution Approach 1:
The flexible tongue features an asymmetric design with a guiding protrusion that creates a one-way guidance system. This asymmetric feature allows the rod-shaped tool to be automatically guided into the tongue groove during disassembly, simplifying the procedure while maintaining strong locking capability through the flexible tongue's engagement
3Ease of operation
If the tongue groove is made accessible for tool insertion, then disassembly is facilitated, but the locking mechanism may become less secure
Solution Approach 1:
The flexible tongue exhibits local quality differentiation: the guiding protrusion provides easy tool access in one location, while the tongue groove maintains secure locking engagement in another location. This localized functional differentiation allows both easy disassembly and secure locking to coexist without compromising either function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates simple and efficient disassembly of locked panels by enabling the rod-shaped tool to be inserted sideways into the insertion groove, automatically guiding it into the tongue groove, thereby releasing the mechanical connection.
Implementation Method 1
The separate and flexible tongue is displaceable inwardly towards a bottom of the insertion groove and outwardly into the tongue groove during a locking of the first and second panel
Data Source
AI summary
Panels are shown, which are provided with a mechanical locking system comprising a separate and flexible tongue allowing connection with a snap action. An outer edge part of the separate flexible tongue comprises a guiding protrusion that facilitates easy disassembly of the panels and that is deformed during locking and/or unlocking.
