Rotary Frame Locking Mechanism for Adjustable Wardrobe Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock and connection devices for frames in wardrobes only allow for reciprocal position fixing through sliding movements, failing to accommodate rotational movements between frames, which limits adaptability to different wardrobe dimensions and configurations.
Innovation Solution
A lock and connection device featuring two parts that can be manually rotated to stretch elastic fins, blocking further sliding between rods, and utilizing geometric coupling means with stop screws to secure frames in any reciprocal position, including rotational configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stop screws are used to fix the rods in reciprocal positions through sliding movement, then the position can be fixed, but the device cannot accommodate rotational movements between frames
Solution Approach 1:
The lock and connection device is designed to perform multiple functions: it can fix rods in reciprocal positions through both sliding movements and rotational movements. The two parts (5a, 6a) with elastic fins and geometric coupling means create a universal mechanism that adapts to different movement types without requiring separate locking mechanisms for each movement type.
Solution Approach 2:
The device transitions from a static locking mechanism (stop screws) to a dynamic one where elastic fins can stretch and compress to accommodate different movement types. The geometric coupling means with stop screws work in conjunction with the elastic fins to provide adaptive locking that responds to the type of movement being applied.
2Adaptability or versatility
If the device is designed for sliding movements only, then the structure is simple, but it fails to accommodate rotational movements between frames
Solution Approach 1:
The same two parts (5a, 6a) and elastic fins mechanism that work for sliding movements also effectively constrain rotational movements. The geometric coupling means with stop screws provide the additional constraint needed for rotational positioning, creating a universal solution that handles both movement types through the same basic structure.
3Reliability
If elastic fins are stretched to block sliding between rods, then the blocking function is achieved, but the device must handle additional forces from rotational movements
Solution Approach 1:
The device combines elastic fins (providing flexibility and blocking force) with geometric coupling means featuring stop screws (providing rigid structural support). This composite approach allows the elastic fins to effectively block movements while the rigid geometric coupling structure handles the additional forces generated by rotational movements, distributing the mechanical loads appropriately.

AI summary
A lock and connection device (1a; 1b) is used for fixing the rods (2a,3a; 2b,3b) of two distinct frames in a reciprocal position, chosen from a plurality of possible reciprocal positions; the first frame acts as a support for a structure for placing objects (4a; 4b) and the second frame is connected, if necessary also indirectly, to the side walls of a wardrobe; in order to make the device allow the fixing of the two frames in reciprocal position both when the two frames are reciprocally translated and when they are reciprocally rotated, according to the invention it is envisaged that the lock and connection device is in two parts (5a,6a; 5b,6b) suitable for being reciprocally rotated by means of the manual action of a user, the reciprocal rotation of the two parts (5a,6a; 5b,6b) determining the fixing of the rods (2a,3a; 2b,3b) of the two frames in said reciprocal position.
