Solution Overview

Problem

Existing methods for processing spacers in insulating glass units are inefficient and lack the ability to securely and reliably handle spacers of different sizes and shapes, as well as apply sealant effectively.

Innovation Solution

A robotic spacer processing system equipped with a multi-axis robot arm and adjustable gripper frame that can handle spacers of varying dimensions and apply sealant to their sides using a sealant applicator, allowing for secure attachment to glass sheets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated equipment is used to handle spacers, then productivity is improved, but the ability to securely handle spacers of different sizes and shapes deteriorates

Engineering Contradiction:

Improveautomation of spacer processingVSAvoidhandling capability for different spacer sizes and shapes

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The gripper frame is designed with adjustable and reconfigurable components that can dynamically adapt to different spacer sizes and shapes. The system transitions from static, fixed grippers to dynamic, adjustable grippers that can be repositioned and reconfigured based on the specific spacer being handled, thereby maintaining both automation and adaptability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The gripper frame is designed as a universal platform that can handle multiple types of spacers through adjustable components. Rather than requiring separate handling mechanisms for each spacer type, a single multi-functional gripper system accommodates various sizes and shapes by adjusting gripper positions and configurations

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Device complexity

If fixed gripper frames are used, then device complexity is reduced, but the ability to process spacers of different sizes and shapes deteriorates

Engineering Contradiction:

Improvesimplicity of gripper frame structureVSAvoidprocessing capability for varying spacer dimensions

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The gripper frame is divided into modular segments with independently adjustable components. Rather than a single complex adjustable mechanism, the system uses multiple simpler modular units that can be independently positioned and configured, reducing overall complexity while maintaining versatility

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system achieves adaptability through parameter adjustments of existing structural elements rather than fundamentally changing the gripper frame design. By adjusting positions, orientations, and configurations of modular components, the system processes different spacer variations while maintaining a relatively simple base structure

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If manual spacer handling is used, then adaptability to different spacer sizes and shapes is improved, but productivity deteriorates

Engineering Contradiction:

Improvehandling flexibility for various spacer typesVSAvoidautomation level of spacer processing

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The automated gripper system incorporates self-adjusting mechanisms that automatically adapt to different spacer configurations without requiring manual intervention. The system performs its own setup and adjustment operations, combining the adaptability of manual handling with the productivity of automation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms to detect spacer characteristics and automatically adjust gripper configurations accordingly. This closed-loop control enables the automated system to adapt to different spacer types by sensing their properties and making real-time adjustments to handling parameters

Inventive Principle:

Principle #23Feedback

4Productivity

If sealant application is integrated into the robotic system, then productivity is improved, but device complexity deteriorates

Engineering Contradiction:

Improveintegration of sealant applicationVSAvoidnumber of integrated components

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The sealant applicator is integrated with the robotic gripper system, combining two functions (handling and sealing) into a single coordinated mechanism. Rather than separate stations requiring transfer operations, the sealant application is merged with the spacer handling process, improving productivity while managing complexity through functional integration

Inventive Principle:

Principle #5Merging (Combining)
