Solution Overview

Problem

Current systems for loading commercial vehicles do not enable continuous loading using a reusable chute, leading to inefficiencies and potential delays, especially when vehicles are far apart or when human errors occur.

Innovation Solution

A system utilizing a reusable 'trouser chute' that branches material flow via gravity, combined with a passage control system, presence sensors, and a computer system to manage the switching states of the chute based on data from presence and material level detection sensors, ensuring continuous loading across multiple vehicles arranged in rows.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single reusable chute is used to load commercial vehicles sequentially, then the device complexity is reduced, but the productivity decreases due to loading interruptions and waiting time

Engineering Contradiction:
Improvechute system complexityVSAvoidloading efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The chute system is segmented into multiple independent chutes (first chute, second chute, third chute) that can operate simultaneously or independently. Each chute can serve different vehicles at different times, allowing parallel loading operations and eliminating the sequential bottleneck of a single chute system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multiple chutes are designed to serve universal loading functions for different commercial vehicles. The system can dynamically assign any chute to any vehicle based on readiness and position, making the chute infrastructure multi-functional and adaptable to varying loading demands.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If vehicles are positioned hundreds or thousands of meters apart, then the adaptability of the loading system increases, but the loss of time increases due to vehicle movement and positioning delays

Engineering Contradiction:
Improvevehicle positioning flexibilityVSAvoidvehicle positioning time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Vehicles are positioned in advance in designated rows (front row, middle row, rear row) and prepared for loading before actually needing to be loaded. The system pre-positions multiple vehicles at different distances from the loading point, so when one vehicle is being loaded, others are already in position and ready to receive material, eliminating waiting time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous loading action by having multiple vehicles in different rows at various stages of readiness. While one vehicle is being loaded, another is moving into position, and a third is being prepared, ensuring the loading process never stops and material flow remains continuous despite vehicles being spread over large distances.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If multiple rows of vehicles are used with vehicles facing opposite directions, then the productivity increases through parallel loading, but the device complexity increases due to traffic control requirements

Engineering Contradiction:
Improveparallel loading capacityVSAvoidtraffic control system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

A computer system acts as an intermediary controller that manages the complex traffic control requirements. The computer receives data from presence sensors and material level sensors, processes this information, and automatically controls the chutes and traffic flow, simplifying the overall system architecture by centralizing control logic rather than requiring complex distributed control mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback loops where presence sensors detect vehicle positions and material level sensors monitor loading status, with this data fed back to the computer control system. The computer adjusts chute operation and traffic control based on this real-time feedback, enabling automated coordination of multiple vehicles in opposite rows without requiring manual traffic management.

Inventive Principle:
Principle #23Feedback

4Measurement precision

If presence sensors and material level sensors are deployed for each vehicle, then the measurement precision increases for loading control, but the device complexity increases due to the sensor network

Engineering Contradiction:
Improvevehicle presence and material level detection accuracyVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The presence sensors and material level sensors are merged into a unified sensor network managed by a single computer system. Rather than treating these as separate independent systems, they are integrated so that the computer receives combined data from all sensors and coordinates chute operation based on the aggregate information, reducing overall system complexity through consolidation.

Inventive Principle:
Principle #5Merging (Combining)
