Solution Overview

Problem

The existing methods for reconfiguring coupling devices on work centers, such as suction cups or clamps, require numerous manual or automatic operations, making the process time-consuming and economically inefficient, especially when transitioning between machining operations.

Innovation Solution

A method that involves acquiring initial and target arrangements of coupling devices, matching them by type and position, and generating commands to minimize the number of steps required to reposition the devices, using a central control unit and display device to guide operators or automated systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual positioning of coupling devices is used, then flexibility in reconfiguration is achieved, but the number of operations and time required increases significantly

Engineering Contradiction:
Improvereconfiguration flexibilityVSAvoidrepositioning time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical positioning operations with an automated control system that uses sensors to detect coupling device positions and a control unit to calculate and execute optimal reconfiguration sequences, thereby reducing repositioning time while maintaining flexibility

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

Solution Approach 2:

The system enables self-service reconfiguration by automatically detecting the current arrangement of coupling devices, computing the optimal transformation sequence to the target arrangement, and executing the repositioning operations without requiring manual intervention for each individual device

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If multiple coupling devices are repositioned individually, then precise positioning is achieved, but the complexity of the reconfiguration process increases

Engineering Contradiction:
Improvepositioning precisionVSAvoidreconfiguration process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The control unit serves multiple functions: it detects current positions of all coupling devices, stores reference arrangements, calculates optimal reconfiguration sequences, and controls the positioning actuators, thereby managing the complex reconfiguration process through a single multi-functional system

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

Solution Approach 2:

The system performs preliminary detection and calculation of the optimal reconfiguration sequence before actual repositioning begins, allowing all coupling devices to be repositioned in a coordinated manner rather than individually, reducing overall process complexity

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If coupling devices are removed and repositioned freely, then adaptability to different machining operations is improved, but the number of operations required increases

Engineering Contradiction:
Improvemachining operation adaptabilityVSAvoidreconfiguration speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system implements dynamic reconfiguration by allowing coupling devices to be removed and repositioned based on real-time detection of their current positions and the calculated optimal sequence, enabling rapid adaptation to different machining operations while minimizing the number of handling operations through intelligent sequencing

Inventive Principle:
Principle #15Dynamics
