Solution Overview
Problem
Existing mail sorting machine drive mechanisms are complex and difficult to assemble, with individual components not optimized for compactness and space efficiency.
Innovation Solution
A drive mechanism for a mail sorting machine with a base plate that integrates a shaft, bearing assembly, stator, and rotor, where the base plate serves as a support and heat dissipation element, allowing for simple assembly and compact installation, featuring a connection dome for easy rotor installation and ribs for stability, along with a heat dissipation area between the base plate and stator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual components (base plate, shaft, bearing assembly, stator, rotor) are arranged separately, then each component can be manufactured independently, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple individual components (base plate, bearing assembly, stator, rotor mounting structures) into an integrated base plate assembly. The bearing assembly is mounted directly on the base plate, the stator is secured to the base plate, and the rotor is rotatably mounted on the base plate, creating a pre-assembled unit that reduces overall assembly complexity while maintaining independent manufacturability of sub-components.
Solution Approach 2:
The base plate serves multiple functions simultaneously: it provides structural support, mounts the bearing assembly, secures the stator, and provides mounting surfaces for the rotor. This multi-functionality reduces the number of separate components needed and simplifies the overall assembly process.
2Ease of manufacture
If components are arranged separately, then manufacturing and maintenance are easier, but the final assembly occupies more space and is less compact
Solution Approach 1:
By integrating the bearing assembly, stator, and rotor mounting structures onto a single base plate, the patent achieves a compact configuration that minimizes the overall volume occupied by the drive mechanism while maintaining the ability to manufacture and maintain individual components.
3Device complexity
If the base plate is used only as a support structure, then the structure is simple, but heat generated by coils and sheet packets cannot be effectively dissipated
Solution Approach 1:
The base plate is designed to serve dual functions: structural support and heat dissipation. The heat dissipation devices are arranged in the area of the stator on the base plate, allowing the base plate to act as a heat sink while maintaining its structural role.
4Reliability
If the rotor is mounted with complex mounting structures, then the rotor is securely fixed, but the assembly process becomes more difficult and time-consuming
Solution Approach 1:
The rotor mounting structure is integrated with the base plate, combining the mounting function with the existing structural platform. This reduces the number of separate mounting components and simplifies the assembly process while maintaining secure rotor fixation.
