Solution Overview

Problem

Existing positionable robot cells for manufacturing devices, such as sheet metal processing machines, require precise alignment and are limited by a defined positioning grid, making them inflexible and hindering manual operation and setup in new production environments.

Innovation Solution

A positionable robot cell equipped with a self-recognizing sensor device, such as optical, ultrasonic, or magnetic sensors, for autonomous positioning relative to the manufacturing device, allowing flexible placement and integration with a repositioning device for easy movement, along with communication connections for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If centering blocks are arranged on the floor for positioning the robot cell, then the robot cell can be aligned in a specific position relative to the manufacturing device, but there is only a defined positioning grid which limits flexibility

Engineering Contradiction:
Improvepositioning precisionVSAvoidpositioning flexibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical centering block system with an optical sensor-based positioning system. The sensor device detects the position of the robot cell relative to the manufacturing device using optical fields rather than mechanical contact, enabling flexible positioning without being constrained to predefined grid locations on the floor.

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

Solution Approach 2:

The patent introduces a sensor device as an intermediary between the robot cell and the manufacturing device. This sensor acts as a mediator that measures the relative position and enables automatic alignment, eliminating the need for direct mechanical interaction through centering blocks and allowing positioning at any location within the sensor's detection range.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If the robot cell is permanently assigned to a production device, then automatic operation is achieved, but additional work is required when setting up a new production hall and manual operation is hindered

Engineering Contradiction:
Improveautomatic operationVSAvoidsetup flexibility
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The patent makes the robot cell dynamically repositionable rather than permanently fixed. The positioning system allows the robot cell to be moved to different production devices and automatically aligned through sensor detection, enabling both automatic operation and flexible reconfiguration for new production halls or manual operation modes.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the robot cell is repositioned frequently, then flexibility in production layout is improved, but alignment time and setup complexity increase

Engineering Contradiction:
Improveproduction layout flexibilityVSAvoidalignment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements a self-aligning system where the sensor device automatically detects the position of the robot cell relative to the manufacturing device and enables automatic alignment without requiring manual intervention. This self-service positioning capability eliminates time-consuming manual alignment procedures when repositioning the robot cell for different production layouts.

Inventive Principle:
Principle #25Self-service
