Solution Overview

Problem

Current container cleaning devices require manual adjustment of box guides for different container dimensions, leading to inefficiencies, potential damage from excessive force, and increased operator requirements, with malfunctions only detectable after they occur.

Innovation Solution

A device with automatically adjustable container guides and a storage system for container-specific settings, allowing for quick adaptation to varying dimensions, and a rotating mechanism to optimize cleaning access, along with torque monitoring and maintenance features to prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual adjustment of crate guides is used, then the device can be operated with simple structure, but the adjustment time increases and productivity decreases

Engineering Contradiction:
Improveadjustment timeVSAvoidadjustment mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements automatic adjustment mechanisms that dynamically adapt the crate guide positions based on detected container dimensions. The system transitions from static manual positioning to dynamic automated adjustment, enabling rapid reconfiguration when changing container types while maintaining manageable system complexity through modular design.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustment system performs self-adjustment by automatically detecting container dimensions and repositioning guides without operator intervention. The device serves itself by integrating sensors and actuators that autonomously configure the cleaning line for different container specifications, eliminating the need for manual measurement and adjustment.

Inventive Principle:
Principle #25Self-service

2Productivity

If simultaneous adjustment of multiple crate guides is implemented, then adjustment time is reduced, but the risk of excessive force and damage increases

Engineering Contradiction:
Improveadjustment speedVSAvoidadjustment mechanism reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms through torque sensors and force monitoring on each adjustment actuator. When adjusting multiple guides simultaneously, the system continuously monitors the force applied and provides feedback to the control unit, which can adjust the adjustment speed or stop the process if excessive force is detected, preventing damage while maintaining rapid adjustment capability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The adjustment mechanism uses dynamic control where the speed and force of simultaneous guide adjustments are automatically modulated based on real-time conditions. The system can accelerate adjustments when resistance is low and decelerate or stop when excessive force is encountered, enabling fast yet safe multi-guide adjustment.

Inventive Principle:
Principle #15Dynamics

3Reliability

If manual monitoring of crate transport is used, then the device structure remains simple, but malfunction detection is delayed

Engineering Contradiction:
Improvemalfunction detection capabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The monitoring system continuously receives feedback from sensors positioned along the crate transport path, detecting malfunctions such as blocked guides, abnormal container positions, or transport interruptions. This real-time feedback enables immediate detection and alerting, significantly improving reliability compared to manual monitoring while maintaining reasonable system complexity through standardized sensor integration.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Sensors and detectors act as intermediaries between the physical crate transport system and the control unit. These intermediary devices translate physical conditions (container position, guide alignment, transport flow) into electrical signals that the control system can process, enabling automated monitoring without requiring direct human observation of all system components.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If individual manual adjustment of each container guide is performed, then the adjustment mechanism remains simple, but the operator workload increases

Engineering Contradiction:
Improveoperator workloadVSAvoidadjustment efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system performs self-adjustment by automatically detecting container dimensions and repositioning guides without operator intervention. The device serves itself by integrating sensors and actuators that autonomously configure the cleaning line for different container specifications, eliminating the need for manual measurement and adjustment while maintaining ease of operation through a user-friendly interface for initiating adjustments.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The adjustment system is designed to universally handle multiple container types and dimensions through a single automated mechanism. Rather than requiring different adjustment procedures for different container sizes, the system uses sensors to detect container specifications and automatically configures all guides appropriately, reducing operator workload while improving adjustment efficiency across diverse container types.

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