Engineering Contradiction Analysis
1Measurement precision
If a sensor for detecting properties of a medium is disposed in an image formation apparatus to perform medium detection, then medium detection capability is achieved, but detection efficiency is reduced due to sequential processing
Solution Approach 1:
The patent applies preliminary action by performing medium detection using a first detector before the medium enters the conveyance path, and simultaneously using a second detector to detect the same medium at a different location. This allows detection to occur in parallel with other operations, improving efficiency while maintaining accurate medium property measurement.
Solution Approach 2:
The patent introduces a controller as an intermediary that manages multiple detectors and coordinates their operations. The controller receives detection results from both the first detector (on conveyance path) and the second detector (off conveyance path), integrating their data to improve overall detection efficiency without compromising measurement accuracy.
2Productivity
If multiple detectors are used to improve detection efficiency, then detection speed increases, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the detection system where both the first detector and second detector perform the same function of detecting medium properties, but at different locations. This multi-functional approach allows the system to improve detection efficiency through parallel detection while managing complexity by using identical detector types for both measurement points.
Solution Approach 2:
The patent merges the detection functions of multiple detectors under a single controller that coordinates their operations and integrates their results. This combining approach allows the system to benefit from multiple detectors for improved efficiency while reducing overall complexity by centralizing the control and data processing functions.

AI summary
A conveyance device includes a conveyance path on which a medium is carried; a first detector that detects the medium on the conveyance path and generates first property data; and a hardware processor that acquires the first property data and second property data generated by detecting the medium disposed at a position away from the conveyance path.
