Solution Overview

Problem

Current modular systems for forming metal containers face challenges in synchronization of motion transmission between modules, requiring complex and costly mechanical parts, leading to increased production time and costs, especially during emergency stops.

Innovation Solution

An electronically coordinated apparatus with independent devices and a centralized control system, using direct drive motors and absolute encoders for precise motion synchronization, allowing for flexible and modular operation with rapid emergency stopping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If modular systems with direct mechanical connection are used for motion transmission between modules, then motion synchronization is achieved, but the system complexity and cost increase due to sophisticated mechanical parts

Engineering Contradiction:
Improvemotion synchronizationVSAvoidmechanical parts complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical motion transmission system with an electronic control system. Each module is equipped with its own drive motor and controller, and modules communicate their position and status electronically. The central controller coordinates module operations through electronic signals rather than mechanical linkages, eliminating complex gears, shafts, and couplings while maintaining synchronization through software-based position matching and coordination algorithms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If complex mechanical parts are used for synchronization, then motion coordination between modules is improved, but production time increases during emergency stops

Engineering Contradiction:
Improvemotion coordinationVSAvoidemergency stop time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

By replacing mechanical motion transmission with independent electronic control of each module, the system eliminates the mechanical coupling that requires gradual deceleration. Each module can be independently commanded to stop immediately through electronic control signals, reducing emergency stop time from several seconds to near-instantaneous response while maintaining position coordination through electronic communication between modules.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system divides the motion control into independent segments, with each module having its own drive system and control logic. This segmentation allows each module to respond independently to stop commands without being constrained by mechanical linkages to other modules, enabling rapid individual stopping while the central controller coordinates the overall system state.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If electronically coordinated independent devices are used, then flexibility and rapid emergency stopping are improved, but synchronization complexity increases

Engineering Contradiction:
Improveprocessing cycle adjustment flexibilityVSAvoidelectronic coordination system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal communication protocol and control architecture that allows the same electronic coordination system to handle multiple functions: motion synchronization, position tracking, emergency stopping, and processing cycle configuration. This multi-functional approach reduces the need for separate specialized systems for each function, managing electronic complexity through integration rather than proliferation of separate components.

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