Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual control of hydraulic cylinder extension based on angle indicators is used, then the unloading process can be completed, but the unloading efficiency is low and unloading time varies significantly
Solution Approach 1:
The patent implements feedback control by using pressure sensors to detect the real-time weight of bulk goods in the container and automatically adjusting the hydraulic cylinder extension based on this feedback. The control system compares the detected weight with preset weight thresholds and automatically controls the hydraulic cylinder to extend or retract, eliminating the need for manual observation of angle indicators and achieving consistent, efficient unloading timing.
Solution Approach 2:
The unloading system performs self-service by automatically monitoring its own state through pressure sensors and autonomously controlling the hydraulic cylinder operation based on detected weight conditions. The system serves itself by making real-time decisions about when to tilt the container and when to return it to vertical position without requiring external manual intervention, thereby standardizing unloading time and improving efficiency.
2Ease of operation
If manual observation of angle indicator is used to control rotating angle, then the container can be tilted for unloading, but the method relies on operator experience leading to variable unloading time
Solution Approach 1:
The patent replaces the mechanical angle indicator observation system with an electronic pressure sensing and automated control system. Instead of mechanically observing angle indicators and manually controlling the hydraulic cylinder, the system uses pressure sensors to detect weight conditions and electronically controls the hydraulic cylinder through automated logic, eliminating reliance on operator experience and ensuring consistent unloading timing.
Solution Approach 2:
The control system acts as an intermediary between the pressure sensors and the hydraulic cylinder. It receives weight detection signals from the pressure sensors, processes them according to preset conditions, and automatically sends control signals to the hydraulic cylinder. This intermediary automation layer eliminates the need for direct manual operation while ensuring reliable and consistent unloading timing across different operations.
3Productivity
If the synthetic resin container is tilted for unloading, then goods can flow out, but the tilting process requires precise control to ensure complete unloading
Solution Approach 1:
The patent uses parameter changes in the form of weight thresholds to control the tilting process. The control system monitors the weight parameter detected by pressure sensors and automatically adjusts the container tilt angle based on preset weight thresholds. When the weight drops below certain thresholds, the system automatically returns the container to vertical position, ensuring precise control of the tilting process without requiring manual angle measurement, thereby achieving both high unloading speed and complete emptying.

AI summary
The present application provides an unloading method for a synthetic resin container, including: maintaining a synthetic resin container at a vertical position, opening an unloading door on a side wall of the synthetic resin container, and when a detection signal of a pressure sensor arranged at a bottom of the synthetic resin container satisfies a preset condition, controlling the synthetic resin container to start to tilt with a long side of a bottom wall as an axis; controlling the synthetic resin container to gradually tilt from the vertical position to a tilted position within a first preset duration; and after the synthetic resin container reaches the tilted position, controlling the synthetic resin container to move from the tilted position to the vertical position within a second preset duration. The technical solution of the present application effectively solves the problem of low unloading efficiency of the synthetic resin container in the related art.
