A detent device with a disc-shaped body and U-shaped, C-shaped, V-shaped, L-shaped, groove-shaped, or trapezoidal detent mouth, combined with a rotating disc and gear system for torque transmission, including a fixed shaft, detent gear, and bridge gear, to minimize sliding friction and ensure smooth installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a slideway and sliding shaft structure is used for toner container installation, then the structure is simple, but the friction force is large causing easy wear of key parts
Solution Approach 1:
The patent replaces the traditional slideway-sliding shaft mechanical structure with a magnetic field-based detent mechanism. The detent device uses magnetic attraction between the detent main body and the toner container to achieve positioning and locking, eliminating the need for physical sliding contacts that generate friction and wear. This substitution of mechanical contact with magnetic field interaction directly resolves the contradiction by maintaining structural simplicity while dramatically improving wear resistance.
Solution Approach 2:
The patent changes the fundamental operating parameter from mechanical friction-based sliding to magnetic field-based attraction. By transforming the interaction mechanism from contact-based to field-based, the system achieves the same functional goals (positioning, locking, conveying) without the harmful effects of sliding friction, thereby improving reliability while keeping the device simple.
2Reliability
If a detent device with rotational friction is used, then sealing performance is improved and part wear is reduced, but the device complexity increases
Solution Approach 1:
The detent device employs a nested structure where the detent gear is integrated within the rotating disc, and the bridge gear connects the detent gear to the fixed gear. The magnetic detent main body is positioned within the rotating disc assembly. This nested arrangement achieves the sealing and wear reduction benefits of rotational friction while containing the complexity within a compact, integrated structure rather than adding separate external components.
Solution Approach 2:
The bridge gear serves as an intermediary element that transmits torque from the fixed gear to the detent gear, enabling the detent mechanism to function without requiring direct complex linkages. This intermediary component simplifies the overall structure by providing a straightforward torque transmission path while maintaining the sealing performance through the rotational friction mechanism.
