Solution Overview

Problem

Existing conveyor systems struggle with real-time control of physical distance between contiguous packages during transfer between conveyors with different speeds and friction conditions, leading to potential sliding and electrical absorption overload, especially when handling heavy batches.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conveyor belts operate at different speeds to arrange items, then item positioning is improved, but package sliding occurs due to friction differences

Engineering Contradiction:
Improveitem positioningVSAvoidpackage sliding
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent applies dynamics by making the friction characteristic variable through a mobile belt with adjustable friction conditions. The mobile belt can change its friction coefficient dynamically to match between conveyors, preventing package sliding while allowing speed variations for precise positioning. This resolves the contradiction by making the system adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the friction parameter of the mobile belt to resolve the contradiction. By adjusting the friction coefficient of the mobile belt, the system can compensate for friction differences between conveyors operating at different speeds, thereby preventing package sliding while maintaining precise positioning capability.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If conveyor speed is increased to improve productivity, then transport efficiency is improved, but electrical absorption overload occurs

Engineering Contradiction:
Improvetransport efficiencyVSAvoidelectrical absorption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies periodic action through controlled acceleration and deceleration ramps. Instead of maintaining constant high speed, the system uses periodic speed variations with optimized ramps that reduce electrical absorption during transitions. This allows high productivity during constant speed phases while minimizing energy overload during speed changes.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent uses dynamics by implementing variable speed control with optimized acceleration and deceleration ramps. The mobile belt and controlled conveyor adjust their speeds dynamically, using smoother transitions that reduce peak electrical absorption while maintaining overall transport efficiency through coordinated motion control.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If real-time detection is implemented to control package distance, then positioning precision is improved, but system complexity increases

Engineering Contradiction:
Improvepackage distance controlVSAvoiddetection and control system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses the mobile belt as an intermediary element that simplifies the control system. Instead of complex detection and control systems on each conveyor, the mobile belt passively mediates the friction matching between conveyors, achieving precise package distance control through its adaptive friction characteristic rather than active sensing and control mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)
