Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a standard sorting machine with multi-column divergence area is used, then packages can be sorted efficiently, but design redundancy occurs and conveying efficiency decreases when handling large packages

Engineering Contradiction:
Improvepackage sorting efficiencyVSAvoiddesign redundancy
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent removes the divergence area from the standard sorting machine configuration when handling large packages. Since large packages occupy significant space and cannot be effectively separated into multiple columns, the divergence area is extracted/removed to eliminate design redundancy and simplify the system for this specific application scenario.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements a dynamic adjustment mechanism where the belt conveyor speed and package spacing are continuously adjusted based on real-time package detection. The system transitions from fixed multi-column arrangement to a flexible single-column dynamic arrangement that adapts to the actual size and position of large packages, optimizing conveying efficiency.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a single distance-increasing operation is used to create spacing between packages, then the structure is simple, but package jamming occurs and conveying efficiency reduces

Engineering Contradiction:
Improvespacing adjustment structureVSAvoidpackage conveying efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent divides the single distance-increasing operation into multiple staged operations. Instead of one abrupt spacing adjustment, the system uses multiple belt conveyor sections that progressively increase package spacing in stages, preventing package jamming while maintaining structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent ensures continuous package conveying by coordinating multiple belt conveyors to operate at different speeds and spacing intervals. The useful action of package transport continues without interruption as packages move through the staged spacing adjustment zones, eliminating the stop-start nature of single operation spacing increase.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If large packages are conveyed at high speed, then productivity increases, but package jamming risk increases

Engineering Contradiction:
Improvepackage conveying speedVSAvoidpackage jamming risk
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent incorporates package detection devices that continuously monitor package position and spacing in real-time. Based on this feedback, the belt conveyor speed and spacing are dynamically adjusted to maintain optimal conditions, preventing package jamming even at high conveying speeds.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent dynamically changes operational parameters including belt conveyor speed, package spacing, and spacing increment rate based on real-time package characteristics. By continuously adjusting these parameters, the system maintains high productivity while preventing package jamming through adaptive control.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The machine efficiently sorts large packages by eliminating redundant design, reducing jamming, and extending conveyor belt life through synchronized support and spacing adjustments, ensuring safe and efficient operation.

Implementation Method 1

the circulation driving member is in transmission connection with a belt roller in the belt conveyor through the transmission member; and when the belt conveyors in the input belt conveyor, the separation belt conveyor set, and the multi-stage distance-increasing belt conveyor set operate, the belt roller rotates under the driving action of the conveying belt, and in this case, the belt roller drives the circulation driving member to operate through the transmission member

AI summary

A single-package separating and sorting machine for large packages, relates to the field of logistics package sorting apparatuses. The present invention includes an input belt conveyor (1), a separation area (2), and a multi-stage distance-increasing belt conveyor set (3) that are sequentially spliced. In the present invention, a divergence area included in a standard sorting machine is removed, such that the sorting machine is more suitable for conveying and sorting large and heavy packages, and the equipment cost is saved by eliminating a redundant design; and the multi-stage distance-increasing belt conveyor set is arranged, such that when a separation belt conveyor set and a visual inspection system (23) cooperate to convey packages to the multi-stage distance-increasing belt conveyor set in a single column and at a relatively small spacing, by means of multiple distance-increasing adjustments, the multi-stage distance-increasing belt conveyor set adjusts packages fed by the separation belt conveyor set stage by stage to increase the package spacing, so as to adjust the package spacing to a specified spacing at a distal end of the multi-stage distance-increasing belt conveyor set. Compared with distance increasing by means of a single long-duration pause, the efficiency of increasing the distance between the packages is significantly improved, thereby improving the efficiency of separating and sorting the packages by means of the sorting machine, and reducing the jamming of packages.
