Furniture assembly and interlock kit thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture assembly systems with interlock functions lack tolerance for assembly errors, which can lead to malfunctioning of the interlock mechanism and potential safety hazards.
Innovation Solution
The proposed furniture assembly system incorporates an interlock kit that includes a first fitting member, a second fitting member, an auxiliary device, and an interlock mechanism. The kit allows for a predetermined gap between the fitting members, enabling the system to accommodate assembly errors and ensure proper operation of the interlock mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the interlock mechanism uses precise fitting members for accurate operation, then the interlock function is reliable, but assembly errors cause malfunctioning
Solution Approach 1:
The patent changes the dimensional parameters of the fitting members by introducing a predetermined gap between the first and second fitting members. This gap is designed to accommodate assembly errors while maintaining the interlock mechanism's reliability. The gap acts as a parameter adjustment that decouples the precision requirement from the assembly process.
Solution Approach 2:
The patent applies beforehand cushioning by pre-designing the gap between fitting members to cushion or absorb assembly errors. This gap serves as a built-in tolerance buffer that prevents assembly errors from causing malfunctioning, ensuring the interlock mechanism operates reliably even with imperfect assembly.
2Stability of the object's composition
If the fitting members are tightly connected for structural integrity, then the furniture assembly is stable, but assembly errors lead to interlock mechanism malfunction
Solution Approach 1:
The patent modifies the structural parameter by introducing a controlled gap between fitting members. This gap maintains structural integrity while providing tolerance for assembly errors, thus preserving both stability and interlock mechanism reliability.
3Measurement precision
If the interlock mechanism is designed with strict dimensional requirements, then the interlock function is precise, but assembly complexity increases due to tolerance requirements
Solution Approach 1:
The patent simplifies assembly by changing the dimensional parameter to include a predetermined gap. This gap reduces the precision requirements for assembly while maintaining interlock mechanism precision, thereby reducing assembly complexity.

AI summary
A furniture assembly is provided and includes a cabinet body, a drawer and an interlock kit. The interlock kit includes a first fitting member, a second fitting member and an interlock mechanism. The first fitting member is detachably mounted on the cabinet body and has a first predetermined height. The second fitting member is detachably mounted on the drawer and has a second predetermined height. A predetermined gap is defined by a difference between the first predetermined height and the second predetermined height. The interlock mechanism is arranged on the first fitting member. The second fitting member can always be moved by the drawer to cause the interlock mechanism to be operated normally as along as the second fitting member is mounted at a position within a mounting range defined by the predetermined gap and a position of the first fitting member. Besides, a related interlock kit is also provided.
