Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the image forming device uses a fuse-based detection method to identify new toner bottles, then it can detect new bottles, but it fails to accurately detect new bottles when they are replaced after being stored improperly
Solution Approach 1:
The system performs preliminary detection of toner supply status when the toner bottle is first attached, before the fuse cutting operation. This preliminary check ensures that even if the fuse detection fails to recognize a newly replaced bottle, the system has already recorded the initial toner quantity state, allowing for subsequent accurate tracking.
Solution Approach 2:
The system continuously monitors toner quantity through the detector and compares it against expected consumption patterns. When the toner bottle state transitions from new to old, the system uses feedback from toner quantity measurements to verify and update the detection status, ensuring accurate identification even when fuse-based detection fails.
2Ease of operation
If the image forming device updates toner quantity to full-up state when a new bottle is detected, then it recovers toner availability display, but it incorrectly updates to full-up when the bottle is actually empty due to aggregation
Solution Approach 1:
The system performs a preliminary toner quantity measurement using the detector immediately when a new bottle is attached, before updating the user interface. This preliminary action ensures that the system records the actual initial toner quantity (which may be zero due to aggregation) rather than assuming full-up state, preventing incorrect UI updates.
Solution Approach 2:
The system replaces reliance on the mechanical fuse-based detection system with an electrical detection system that measures actual toner quantity. This substitution allows the system to accurately determine true toner availability regardless of the bottle's new/old status, preventing incorrect full-up state updates when toner aggregation has depleted available toner.
3Reliability
If the image forming device requires users to shake toner bottles before attachment, then it improves toner fluidity, but it increases operational complexity and user burden
Solution Approach 1:
The system performs automatic detection and verification of toner supply status through its built-in detector, eliminating the need for users to manually shake bottles. The system self-verify whether toner is actually available in the attached bottle and provides appropriate feedback or error messages, making the operation simple while maintaining reliable toner supply.
Solution Approach 2:
The system replaces the mechanical shaking requirement with an electrical detection system that automatically measures toner quantity and fluidity status. The detector can identify when toner has aggregated or depleted, and the system responds by providing appropriate guidance or error messages, eliminating the need for users to perform manual shaking operations.
4Measurement precision
If the image forming device uses fuse cutting to mark toner bottles as old, then it tracks bottle usage, but it cannot reset the state when bottles are removed and reattached
Solution Approach 1:
The system performs preliminary detection and recording of the toner bottle's initial state when first attached, storing this information before any fuse cutting operations. This preliminary record allows the system to track the bottle's true usage status independently of the fuse state, enabling proper state management when bottles are removed and reattached.
Solution Approach 2:
The system continuously monitors toner quantity through the detector and uses this feedback to dynamically adjust the bottle state classification. When a bottle is reattached, the system compares the current toner quantity against the initial recorded quantity and updates the state accordingly, providing flexible state management that adapts to various usage scenarios including removal and reattachment.

AI summary
An image forming device may comprise: an attaching unit to which a removable toner bottle is attached; a toner storage that stores toner supplied from the toner bottle attached to the attaching unit; a detector that detects an empty state of toner in the toner storage; and a hardware processor that: supplies toner to the toner storage from the toner bottle when the toner bottle attached to the attaching unit is new; and switches a state of the toner bottle to an old state from a new state if the empty state detected by the detector is released.
