Drive Device Recording Working Status for Failure Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drive devices lack the ability to independently record and retrieve working status data, making it difficult to diagnose failures and improve performance, especially when remote control hosts are disconnected or unavailable.
Innovation Solution
A drive device with a sensing unit that monitors the working status of the drive mechanism and records data in a storage unit, allowing for post-failure analysis, comprising a motor, gear train, temperature, angle, voltage, current, control signal, acceleration, and angular speed sensors, with data stored in a memory or memory card for later retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drive devices rely on remote-control hosts for recording working status data, then the recording function can be centralized, but the drive devices cannot independently record data when disconnected from remote control hosts
Solution Approach 1:
The drive device is equipped with its own sensing unit and storage unit, enabling it to independently sense and record working status data without relying on external remote-control hosts. This self-service capability ensures data can be recorded even when disconnected from remote control systems.
Solution Approach 2:
A storage unit is introduced as an intermediary between the sensing unit and remote control host. The storage unit temporarily holds working status data locally, serving as a buffer that allows the drive device to maintain recording capability independent of remote control host availability.
2Loss of information
If working status data is stored in remote control hosts, then data can be accessed remotely, but data loss occurs when connection is lost or power fails
Solution Approach 1:
The drive device performs preliminary recording of working status data in its local storage unit before any potential connection loss or power failure occurs. This ensures data is preserved in advance, preventing information loss when remote control host becomes unavailable.
3Reliability
If drive devices have independent recording capability, then data can be recorded during disconnection, but the device structure becomes more complex
Solution Approach 1:
The sensing unit and storage unit are integrated within the drive device structure, merging multiple functions into a unified system. This consolidation achieves independent recording capability while managing complexity through integrated design rather than separate distributed components.

AI summary
A drive device capable of recording a working status includes: a drive mechanism, including a housing, an actuating unit configured inside the housing and a transmission unit configured inside the housing and in connection with the actuating unit; a sensing unit, configured inside the housing and in electric connection with the actuating unit; and a storage unit, configured inside the housing and in electric connection with the sensing unit. Whereby, the drive device can be installed inside a unmanned control or automatic machine, utilizes the sensing unit to sense a working status of the drive mechanism, and records working status data in the storage unit; the working status stored in the storage unit can be read after the machine fails or is damaged, the working status of the drive mechanism of the damaged machine, and the cause of the failure occurrence is clarified, as a basis for subsequent performance improvement.
