Auxiliary Power Supply Device for Encoder Data Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary power supply systems risk losing encoder information when the main battery is replaced, especially if the spare battery's remaining capacity is insufficient, leading to data loss in industrial machines like robots.
Innovation Solution
An auxiliary power supply device with a backup power source, an auxiliary power source, a remaining capacity determination unit, a display unit, and a switch to indicate insufficient capacity, ensuring continuous power to encoders and preventing data loss by alerting users to replace the backup power source only when the auxiliary power source has sufficient capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spare battery is provided to maintain stored contents when the main battery runs out, then information on encoder positions can be held, but the stored contents are lost if the main battery is replaced while the spare battery's remaining capacity is insufficient
Solution Approach 1:
The system performs preliminary action by detecting the remaining capacity of the spare battery in advance and displaying a warning when it falls below a threshold. This allows users to replace the spare battery before it becomes insufficient, preventing encoder information loss during main battery replacement. The warning display mechanism enables proactive maintenance rather than reactive damage control.
2Device complexity
If the remaining capacity of the auxiliary power source is not monitored, then the device complexity is reduced, but the encoder information may be lost during battery replacement
Solution Approach 1:
The system implements feedback by continuously monitoring the remaining capacity of the spare battery and providing visual feedback through a display unit when the capacity falls below a threshold. This feedback mechanism ensures users are aware of the spare battery's status and can take appropriate action, maintaining encoder information integrity without requiring complex monitoring systems.

AI summary
An auxiliary power supply device supplies electric power to an encoder when supply of electric power of a control device is cut off, and includes: a backup power source for supplying backup electric power to the encoder when supply of electric power of the control device is cut off; an auxiliary power source for supplying electric power to the encoder when the backup power source is removed; a remaining capacity determination unit for determining the remaining capacity of the auxiliary power source; a display unit for displaying an indication that the remaining capacity is insufficient when the remaining capacity determined by the remaining capacity determination unit is lower than a threshold; and a switch for actuating the display unit.
