Solution Overview
Problem
Existing precision devices face challenges in accurately tracking the consumption degree of replaceable components, particularly in minimizing storage rewriting and ensuring accurate recognition of component usage history, especially when components are replaced, as existing solutions often require frequent rewriting and are inefficient in power management.
Innovation Solution
A device with a replaceable component that includes a component-side storage, transmitter/receiver, hardware processor, and power generator, which uses electromagnetic waves and vibration-generated power to manage and update consumption data, allowing for efficient rewriting and accurate recognition of component usage even when power is off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the consumption degree is rewritten in the component-side storage each time one image forming operation is finished, then the accurate consumption degree can be stored in the component-side storage, but the number of rewriting times increases and consumption of the component-side storage is expedited
Solution Approach 1:
The patent extracts the consumption degree information from the main body storage and transfers it to the component-side storage only when needed (at detachment). This eliminates continuous rewriting operations and stores the data externally on the component, resolving the contradiction between accuracy and storage consumption.
Solution Approach 2:
The patent performs the data transfer operation in advance at the moment of detachment, before the component is removed. By updating the component-side storage at this specific timing rather than after each operation, the system ensures accurate consumption tracking while minimizing rewriting frequency to just one update per detachment event.
2Loss of information
If the information in the storage on the main body side is written in the storage on the component side each time one image forming operation is finished, then the accurate consumption degree can be reflected on the component side, but the rewriting operation consumes power and increases storage consumption
Solution Approach 1:
The patent extracts the consumption degree information from the main body storage and transfers it to the component-side storage only at detachment events. This eliminates continuous power-consuming rewriting operations while ensuring the component always has the latest consumption data when removed from the device.
Solution Approach 2:
Instead of continuous or frequent rewriting operations, the patent implements periodic action by updating the component-side storage only at specific intervals - specifically at the moment of detachment. This reduces power consumption significantly while maintaining data accuracy.
3Reliability
If replacement of components is performed in a state where power is off since it is dangerous, then safety is improved, but the information such as the use history in the storage on the main body side cannot be written in the storage on the component side
Solution Approach 1:
The patent performs the data transfer operation in advance at the moment of detachment, before the component is removed and before power is turned off for safety. This preliminary action ensures that all consumption degree information is successfully transferred to the component-side storage while maintaining the safe practice of powering off during actual component replacement.
