Rotating Number Lock for Visible Dial Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing number locks for electronic devices in public places often have number rollers that face downward or rearward when engaging with keyholes, making it difficult for users to see the numbers, hindering operation.
Innovation Solution
A number lock design featuring a main rod with number rollers, a casing with an operating block and ejector, and buckles with arced sections, allowing the main rod, casing, and push knob to rotate axially, ensuring the number rollers are easily visible and operable while maintaining the lock's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the engaging arm engages with the keyhole of the electronic device, then the lock can secure the device, but the number roller faces downward or rearward making it difficult for users to see and operate
Solution Approach 1:
The lock body is designed to be rotatable relative to the engaging arm through a rotating mechanism. After the engaging arm engages with the keyhole, users can rotate the lock body to adjust the orientation of the number roller, making it visible and accessible for operation. This dynamic adjustment resolves the contradiction by allowing the system to transition from a fixed orientation (where visibility is poor) to an optimized orientation (where visibility and operability are improved) while maintaining the locking function.
2Ease of operation
If the number roller is positioned for easy viewing, then usability improves, but the locking mechanism may not properly engage with the keyhole
Solution Approach 1:
The rotating mechanism allows the lock body to be independently positioned relative to the engaging arm. Users can first engage the lock with the keyhole, then rotate the lock body to achieve the optimal viewing angle for the number roller. This dynamic separation of functions ensures that both reliable engagement and easy operability can be achieved at different stages of use.
Solution Approach 2:
The lock system is divided into separate functional components: the engaging arm that interfaces with the keyhole and the lock body containing the number roller. This segmentation allows each component to be optimized for its specific function while maintaining the ability to work together through the rotating mechanism.
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
Enables users to easily view and operate the number rollers during locking and unlocking, enhancing usability and security by allowing the number rollers to be adjusted to a convenient viewing position without compromising the lock's anti-theft functionality.
Implementation Method 1
The casing has an elastic piece pushing against each number roller for positioning
Implementation Method 2
The ejector is a round bar with a tapered head, and each buckle respectively has a receiving slot for accepting the ejector before ejection while are closed to each other

AI summary
A number lock has a main rod, a casing, a push knob and two buckles. The main rod is jacketed with a plurality of number rollers, and each number roller is capable of controlling movement of the main rod. One end of the main rod has an operating block and an ejector. The casing has two corresponding pieces enclosing the main rod and exposes a portion of each number roller. The casing further has a displacement space for accepting the operating block and a semispherical space for accepting the ejector. The casing has an elastic piece pushing against each number roller for positioning. One end of the casing is provided with a round rod, and the round rod has a ball socket connected to a cable. The push knob is partially disposed in the displacement space of the casing and connected to the operating block.
