Figure Wheel Locking Device with Interlaced Rotating Axes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional compound figure wheel locking devices are easily unlocked when the figure wheels are axially disposed in serial, compromising the locking mechanism's effectiveness.
Innovation Solution
The figure wheel locking device incorporates a housing with a key locking mechanism, a pushing assembly, figure-detecting members, and a figure locking mechanism, where the first and second rotating axes are interlaced to prevent axial disposition of figure wheels, ensuring secure locking with either an exact key or figure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the figure wheels are axially disposed in serial, then the device structure is simple, but the locking function is weak and容易被 unlocked
Solution Approach 1:
The patent changes the arrangement dimension of the figure wheels from axial serial disposition to radial disposition around a central axis. The figure wheels are arranged in a radial pattern with their rotation axes perpendicular to the main rotation axis, creating a multi-dimensional configuration that prevents the simple axial stacking and improves locking reliability while maintaining structural compactness
2Ease of manufacture
If the figure wheels are axially disposed in serial, then the manufacturing process is simple, but the security against unauthorized opening is reduced
Solution Approach 1:
The patent reconfigures the figure wheels from an axial serial arrangement to a radial arrangement where each figure wheel rotates around a common central axis. This dimensional change creates a more complex interaction geometry that is harder to manipulate and less susceptible to unauthorized opening, while the manufacturing process remains relatively straightforward through standardized wheel components
3Ease of operation
If the figure wheels are axially disposed in serial, then the device is easy to operate, but the locking mechanism is easily compromised
Solution Approach 1:
The patent transitions from an axial serial arrangement to a radial arrangement where figure wheels are positioned around a central axis. This dimensional reconfiguration maintains operational ease through intuitive rotation while significantly enhancing security by eliminating the vulnerable axial alignment that allows easy manipulation and unauthorized opening

AI summary
A figure wheel locking device includes a housing, a key locking mechanism, a pushing assembly, a plurality of figure-detecting members, and a figure locking mechanism. The key locking mechanism is sleeved in the housing. The pushing assembly is movably located in the housing. Each of the figure-detecting members has a first rotating member. The figure locking mechanism has a plurality of figure wheels, and each of the figure wheels has a second rotating member. The direction of the first rotating member is defined as a first rotating axis. The direction of the second rotating member is defined as a second rotating axis. The second rotating axis and the first rotating axis are interlaced to each other. The second rotating member drives the first rotating member. Thereby, the compound locking device having a key locking mechanism and a figure locking mechanism prevents the figure wheels from becoming axially disposed in serial.
