Wall Cupboard Hooking Assembly With Stable Anti-Disengagement Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-disengagement systems for wall cupboards require multiple operators to manually disable the automatic locking mechanism during dismantling, leading to inefficiency and loss of control, potentially resulting in incorrect hooking and unstable assembly.
Innovation Solution
The proposed assembly group features anti-disengagement means with movable laminas and actuation mechanisms, such as saw-toothed notches, beads, or gripping flaps, allowing for controlled movement between locking and unlocking positions without the need for continuous operator intervention, ensuring stable and secure engagement/disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic anti-disengagement systems are used, then safety is improved, but device complexity increases and requires multiple operators for dismantling
Solution Approach 1:
The patent combines multiple anti-disengagement mechanisms into a single integrated plaque structure. The movable lamina and elastic element work together as one unified system rather than separate mechanisms, reducing the number of independent components while maintaining safety functionality.
Solution Approach 2:
The elastic element automatically returns the movable lamina to its initial blocking position after the hooking means is inserted, without requiring continuous operator intervention. The system serves itself by using the insertion force to trigger the elastic recovery mechanism.
2Reliability
If automatic anti-disengagement systems are used, then safety is improved, but ease of operation deteriorates during dismantling
Solution Approach 1:
The patent extracts the anti-disengagement function from a complex multi-operator system and implements it through a single plaque with an integrated movable lamina mechanism. This allows one operator to control the disengagement of multiple hooking means simultaneously by acting on one plaque only.
Solution Approach 2:
The movable lamina mechanism serves multiple functions: it blocks the passage span for safety during assembly, allows passage during controlled disassembly, and can be reset automatically. One mechanism handles multiple operational states and multiple hooking means.
3Reliability
If automatic anti-disengagement systems are used, then safety is improved, but loss of control increases
Solution Approach 1:
The movable lamina provides visual and tactile feedback to the operator about the engagement state. When the lamina blocks the passage span, the operator can see and feel the safety mechanism is active. When moved to allow passage, the operator receives immediate feedback that disengagement is permitted.
4Reliability
If multiple operators are required for dismantling, then safety is maintained, but productivity decreases
Solution Approach 1:
The patent merges the control of multiple hooking means into a single plaque mechanism. One operator acting on one plaque can simultaneously control the disengagement of multiple hanging brackets, eliminating the need for multiple operators working in parallel.
Solution Approach 2:
The movable lamina is pre-positioned to block the passage span during assembly, ensuring safety is automatically maintained. During dismantling, the operator only needs to perform the single action of moving the lamina, and the system is already prepared to allow controlled disengagement of all hooking means.
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
This solution enables efficient and controlled disengagement of wall cupboards, maintaining safety and preventing unintended disengagement, while allowing for single-operator operation and reducing the risk of assembly malfunctions.
Implementation Method 1
an elastic element, such as a metallic lamina or spring, which moves, under thrust, to allow the hooking means to pass into an engagement seat and then returns (elastically) to its initial position

AI summary
A wall assembly group (1A, 1B, 1C) of a wall cupboard of the type comprises: - a plaque (3A, 3B, 3C) to be fixed to a wall; - hooking means (2A, 2B, 2C) which can be coupled with said plaque; - anti-disengagement means (30A, 30B, 30C) which can be moved at least in a first stable position wherein, in a hooking condition, said means (2A, 2B, 2C) are engaged with the plaque (3A, 3B, 3C) and intercept said anti-disengagement means (30A, 30B, 30C) to prevent the decoupling of the same hooking means from the plaque (3A, 3B, 3C). According to the invention, said anti-disengagement means (30A, 30B, 30C) can be moved in a second stable position in which they release said hooking means (2A, 2B, 2C) to allow the decoupling of the same from the plaque (3A, 3B, 3C).
