Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing key ring technologies are inconvenient for mounting and dismounting keys due to complex structures that can easily get stuck, making key management difficult.
Innovation Solution
A press control key ring featuring a split ring with a locking module comprising an inner and outer casing, an elastic member, and a press block that allows for easy opening and closing of the split ring for key insertion and removal, using an annular wire rod with a locking mechanism that includes supporting blocks and a spring for secure key management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple split ring is used, then the structure is simple and easy to manufacture, but mounting and dismounting keys requires force and is inconvenient
Solution Approach 1:
The locking module is divided into separate components: inner casing, outer casing, elastic member, and press block. This segmentation allows each part to be manufactured independently and assembled, maintaining manufacturing simplicity while enabling the complex locking function for convenient key mounting and dismounting.
Solution Approach 2:
The press block is designed to be movable within the inner casing, controlled by the elastic member. When the press block moves, it shifts the annular wire rod to open the opening. This dynamic mechanism transforms the simple split ring into a convenient locking system that requires minimal force for operation.
2Ease of operation
If a complicated locking mechanism is used to facilitate key mounting and dismounting, then ease of operation is improved, but device complexity increases and fabrication becomes difficult
Solution Approach 1:
The locking mechanism uses a nested structure where the press block is housed within the inner casing, which is itself housed within the outer casing. The elastic member is nested within the inner casing. This nesting approach consolidates multiple components into a compact unit, reducing overall device complexity while maintaining the convenient locking function.
Solution Approach 2:
The elastic member automatically returns the press block to its initial position after the key is mounted or removed. This self-service feature eliminates the need for additional mechanisms to reset the locking block, simplifying the overall structure while ensuring reliable operation for repeated key mounting and dismounting.
3Ease of operation
If a complicated locking mechanism is used, then ease of operation is improved, but the mechanism can easily get stuck making key removal difficult
Solution Approach 1:
The press block is designed to be extractable from the inner casing through the first open end. When the press block is extracted, it creates sufficient space for the annular wire rod to move freely and open the opening completely. This extraction design prevents the mechanism from getting stuck by ensuring full separation of the locking components during key removal.
Solution Approach 2:
Before the key can be mounted or removed, the press block must first be extracted to open the opening. This preliminary action ensures that the path for key insertion or removal is completely clear, preventing any potential sticking or jamming during the subsequent key mounting or dismounting operation.
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 easy and secure mounting and dismounting of keys by allowing controlled sliding movement of the annular wire rod, reducing the risk of keys getting stuck and simplifying the process, while maintaining structural rigidity and capacity for multiple keys.
Implementation Method 1
The elastic member is mounted in the inner casing, having one end thereof fastened to the inner bottom wall of the inner casing
Implementation Method 2
The elastic member is mounted in the inner casing, having one end thereof fastened to the inner bottom wall of the inner casing
