Solution Overview

Problem

Unloading synthetic resin containers on a vehicle body results in low unloading efficiency due to site constraints, leading to slow vehicle turnover speed.

Innovation Solution

An unloading platform with a tilting frame that can switch between initial and tilted positions, allowing containers to be carried and raised off the vehicle body, featuring limiting frames to secure the container during unloading and a lifting mechanism for smooth transition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If unloading is performed on a vehicle body, then the unloading process can be completed at the vehicle location, but the vehicle turnover speed is slow and unloading efficiency is low

Engineering Contradiction:
Improveunloading efficiencyVSAvoidvehicle turnover time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The unloading system is segmented into a platform portion and a tilting frame that can be independently positioned. The tilting frame carries the container away from the vehicle body to a dedicated unloading position, separating the unloading operation from the vehicle location. This allows the vehicle to remain stationary while the container is unloaded at an optimized position, improving unloading efficiency and reducing vehicle turnover time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tilting frame acts as an intermediary carrier between the vehicle body and the unloading position. It receives the container from the vehicle, transports it to the platform, and enables unloading without requiring the vehicle to move or reposition. This intermediary mechanism resolves the contradiction by decoupling the vehicle location constraint from the unloading operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If the tilting frame raises the container off the vehicle body, then unloading speed increases, but the container may become unstable or fall off

Engineering Contradiction:
Improveunloading speedVSAvoidcontainer stability
Core Design Contradiction:
SpeedVSStability of the object's composition

Solution Approach 1:

The limiting frame is positioned in advance to prevent the container from falling off before it can happen. The limiting frame includes limiting members that create a physical barrier against the container, providing preliminary protection against instability and falling during the tilting and unloading process. This preventive measure allows the tilting frame to raise the container quickly while maintaining safety.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The limiting frame serves as an intermediary safety mechanism between the tilting frame and the container. It monitors and restricts the container's movement during the tilting process, providing stable support while allowing the rapid motion needed for efficient unloading. The limiting frame mediates between the dynamic motion of the tilting frame and the stability requirements of the container.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention provides an unloading platform and an unloading method. The unloading platform includes: a platform portion; a tilting frame, used for carrying a container, the tilting frame having a first working state, wherein when the tilting frame is in the first working state, a first side of the tilting frame is hingedly connected to the platform portion, and a second side of the tilting frame has a first initial position in which it is in contact with the platform portion and a first tilted position in which it is raised relative to the platform portion; lifting members, provided between the platform portion and the tilting frame, wherein the lifting members drive the tilting frame to switch between the first initial position and the first tilted position; and a first limiting frame, provided on a first side portion of the platform portion, wherein when the tilting frame is in the tilted position, the tilting frame or the container is in limiting engagement with the first limiting frame. The technical solution of the present application effectively solves the problem in the related art that unloading a synthetic resin container on a vehicle body results in low unloading efficiency.
