Code-Changeable Dial Wheel Assembly Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dial wheel devices for combination locks are inconvenient to assemble due to their complex components and multiple parts, making the code-changing process cumbersome.
Innovation Solution
A simplified code-changeable assembly and dial wheel device design featuring a controller with a positioning rod, adjuster, and dial wheel module, where the inner ring is selectively inserted into retaining grooves of the outer ring, allowing for easy code resetting by rotating the adjuster to disengage and reengage the rings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional dial wheel assemblies use multiple components (retaining element, pushing element, torsion spring, outer ring with retaining recess), then the code-changing function is achieved, but the assembly complexity increases and convenience of assembly deteriorates
Solution Approach 1:
The patent combines the retaining element, pushing element, and torsion spring into a single integrated component mounted on the inner ring. This merging of multiple functional elements into one component directly reduces assembly complexity while maintaining the code-changing capability through the coordinated action of the integrated component with the outer ring's retaining grooves
2Adaptability or versatility
If conventional dial wheel assemblies use multiple components and parts, then code-changing functionality is achieved, but the convenience of assembly deteriorates
Solution Approach 1:
Multiple components (retaining element, pushing element, torsion spring) are merged into a single integrated component that mounts on the inner ring, reducing the number of parts to assemble and improving ease of manufacture while preserving code-changing functionality
Solution Approach 2:
The integrated component performs multiple functions simultaneously: it provides retaining engagement through the retaining portion, pushing action through the pushing element, and spring force through the torsion spring, making the component multi-functional and simplifying the overall assembly structure

Function Achieved in This Case
The design simplifies the assembly and operation of the dial wheel device by reducing the number of components and providing a tactile indication during code resetting, making it easier for users to change codes while maintaining the device's functionality.
Implementation Method 1
The torsion spring is mounted on the inner ring and connected to the controller

AI summary
A dial wheel device has a controller. The controller has a positioning rod. An adjuster, a dial wheel module, a seat and a restoring element are mounted on the positioning rod. The dial wheel module has multiple dial wheel assemblies. Each dial wheel assembly has an outer ring and an inner ring. In the code-unchanged state, the outer ring and the inner ring are coactive. In the code-changing state, the adjuster is rotated and the guide element forms a lateral displacement to push the inner ring, and the outer ring and the inner ring are non-coactive. The outer ring is turned to reset the code. When the code-changing state is finished, the adjuster is rotated again and the outer ring and the inner ring are coactive again. Therefore, the components of the code-changeable assembly are simplified and the dial wheel device is easy to assemble and operate.
