Dynamic Consumable Payload for Accurate Remaining Life Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing devices inaccurately estimate the remaining life of consumable items like toner cartridges after remanufacture due to mismatched parameters, leading to premature replacement or depletion, resulting in waste and cost inefficiencies.
Innovation Solution
Storing parameters particular to the consumable item in a payload that reflects the specific replacement components, allowing for accurate estimation of remaining life even after remanufacture, by encoding and updating these parameters in the consumable item itself.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manufacturer-specific parameters are programmed into consumable items, then initial estimation accuracy is improved, but adaptability to remanufactured items deteriorates
Solution Approach 1:
The patent changes the parameter storage approach from fixed manufacturer-specific values to dynamic parameters that can be updated. A payload structure is implemented that can store and update parameters particular to the consumable item, allowing the system to adapt to different manufacturers and remanufactured versions while maintaining accurate remaining life estimation.
Solution Approach 2:
The system transitions from static manufacturer-defined parameters to dynamic parameters that can be modified and updated. The payload can be updated with new parameters when consumable items are remanufactured, making the estimation system adaptive rather than fixed, thus resolving the contradiction between initial accuracy and future adaptability.
2Ease of manufacture
If remanufactured consumable items use different components, then cost and availability are improved, but parameter mismatch causes estimation inaccuracy
Solution Approach 1:
The remanufactured consumable item carries its own updated parameters within the payload, allowing it to self-identify its specific characteristics. When installed in the printing device, the payload is detected and used to calculate remaining life based on the actual components present, eliminating the need for manual parameter reconfiguration and ensuring accuracy despite component variations.
Solution Approach 2:
The parameters particular to the consumable item are pre-programmed into the payload during or before remanufacturing. This preliminary action ensures that when the remanufactured item is installed, the printing device immediately has the correct parameters for accurate remaining life estimation, avoiding the parameter mismatch problem.
3Adaptability or versatility
If generic parameters are used for all consumable items, then compatibility is improved, but estimation precision deteriorates
Solution Approach 1:
The system uses a payload structure that can accommodate both generic and manufacturer-specific parameters. The payload is configured with default generic values for broad compatibility but can be updated with specific parameters for particular consumable items, allowing the system to maintain cross-manufacturer compatibility while achieving high estimation precision when specific parameters are available.
Data Source
AI summary
