Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base height is adjusted manually for different recording medium types, then collision prevention is improved, but setup time and operational complexity increase
Solution Approach 1:
The system pre-establishes multiple base height positions corresponding to different recording medium types. Before image formation, the controller automatically selects and adjusts the base height according to the detected medium type, eliminating manual adjustment and reducing setup time while ensuring collision prevention.
Solution Approach 2:
The base height is made dynamically adjustable through automated control. The controller receives signals about the recording medium type and automatically changes the base height position, transforming a static manual adjustment system into a dynamic automated one that adapts to different medium types without increasing operational complexity.
2Measurement precision
If the detection range is extended to cover the entire conveyance direction, then collision detection accuracy is improved, but device complexity increases
Solution Approach 1:
Instead of using a single sensor to detect the entire conveyance direction, the system employs multiple sensors positioned at different locations along the conveyance path. Each sensor monitors a specific local zone, and the controller integrates information from all sensors to achieve comprehensive collision detection accuracy without requiring overly complex individual sensor systems.

AI summary
An image forming apparatus includes an image forming device, a base, circuitry, and a detector. The image forming device includes a recording head to form an image on a recording medium conveyed in a conveyance direction. The base supports the recording medium and is movable in the conveyance direction. A type of the base is changeable according to a type of the recording medium. The circuitry sets a detection range in the conveyance direction. The detector detects, before the image is formed, a collision between the recording head and the recording medium on the base, in the detection range set by the circuitry.
