Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture box assembly methods require specialized knowledge in carpentry and complex hardware, making them difficult for non-experts to assemble correctly and efficiently.
Innovation Solution
A furniture box assembly system using a bastard tongue and groove mechanism, where panels interlock with complementary shapes and surfaces, allowing for simple alignment and locking without additional hardware, ensuring accurate angles and a clean front appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional assembly methods with hardware accessories (screws, pins, eccentrics) are used, then the assembly can be securely locked, but the device complexity and ease of operation deteriorate due to complicated packaging, preparation, and assembly requirements for non-specialists
Solution Approach 1:
The invention extracts and eliminates the need for separate hardware accessories (screws, pins, eccentrics) by integrating the locking function directly into the panel assembly structure itself. The bastard tongue and groove mechanism with integrated locking grooves and locking tabs provides secure locking without requiring additional components, thus reducing device complexity while maintaining assembly security.
Solution Approach 2:
The assembly system is designed to be self-sufficient, where the panels themselves provide all necessary assembly and locking functions. The bastard tongue and groove structure with integrated locking mechanisms allows the furniture box to be assembled and secured using only the panel components, without requiring external hardware or specialized tools, making it suitable for non-specialist assembly.
2Reliability
If traditional assembly methods with multiple hardware components are used, then the assembly can be securely locked, but the ease of operation worsens due to difficulty in assembly by non-specialists
Solution Approach 1:
By removing the need for separate hardware accessories and specialized assembly tools, the invention simplifies the assembly process to involve only the panel components themselves. The integrated bastard tongue and groove mechanism with locking features requires no specialized knowledge or tools, dramatically improving ease of operation for non-specialists while maintaining secure assembly through the interlocking structure.
Solution Approach 2:
The assembly system is completely self-service, requiring no external hardware, tools, or specialized skills. The panels are designed with built-in bastard tongues, grooves, and locking mechanisms that guide and secure the assembly automatically, allowing any user to assemble the furniture box correctly without training or additional components.
3Ease of operation
If locking grooves open on the front side of panels, then the assembly process is simplified, but the aesthetic appearance deteriorates by revealing the channel and locking mechanism
Solution Approach 1:
The invention applies different functional qualities to different locations of the locking mechanism. The locking grooves are positioned to open on the rear side of the panels, keeping the assembly process accessible while hiding the mechanism from the front view. The bastard tongue and groove structure provides the necessary local interlocking quality at the joint, while the rearward positioning of the groove openings maintains the clean aesthetic appearance of the front faces.
4Adaptability or versatility
If alignment correction is needed during assembly, then the assembly flexibility improves, but the time required worsens due to potential alignment errors along the assembly line
Solution Approach 1:
The bastard tongue and groove structure is designed with built-in alignment guidance features that preliminarily establish correct positioning during the assembly process. The shape and fit of the tongue in the groove provide automatic alignment, allowing for simple correction of alignment errors without requiring complex adjustment procedures or additional time, thus maintaining both flexibility and efficiency.

AI summary
The cabinet has a panel (20) whose locking groove (26) emerges in an assembly housing (21) in a position complementary with that of another locking groove (16) of another panel (10) when the two panels are assembled with each other. An edge bearing surface (15) of the latter panel is applied against an external support surface (25) of the former panel. The grooves are supplemented to form a channel (30) receiving a locking strip, where engagement of a baton strip (11) and the assembly housing ensure blocking in a direction (Y), and the locking strip blocks the assembly.
