Solution Overview

Problem

Existing liquid material supply devices require significant space due to separate dispense and robot controllers, leading to inefficiencies and increased device size.

Innovation Solution

A cable unit with a built-in dispense controller that integrates with the discharge head and robot, eliminating the need for a separate box-shaped dispense controller, reducing device size and weight, and allowing for compact operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate dispense controller and robot controller are used, then control functions are independent and reliable, but device size and space requirements increase

Engineering Contradiction:
Improvecontrol function independenceVSAvoiddevice space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent merges the dispense controller and robot controller into a single integrated controller unit. This consolidation maintains the independent control functions for both dispensing operations and robot movements while eliminating the need for separate controller housings, thereby reducing overall device space requirements without compromising control reliability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated controller is designed to perform multiple functions simultaneously - it controls both the dispense head operations and the robot movements through a unified control system. This multi-functionality allows a single device to replace what previously required two separate controllers, reducing spatial requirements while maintaining full control capabilities

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

2Ease of operation

If separate box-shaped dispense controller is used, then control functions are distinct, but device weight and load on XYZ-driving devices increase

Engineering Contradiction:
Improvecontrol function separationVSAvoiddischarge head load
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The patent combines the dispense controller with the robot controller into one integrated unit, eliminating the separate box-shaped dispense controller. This merger reduces the total weight that the XYZ-driving devices must support while maintaining distinct control functions through software or modular control architecture within the unified controller

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If dispense controller is integrated into cable unit, then device size is reduced and space is saved, but cable unit complexity increases

Engineering Contradiction:
Improvedevice spaceVSAvoidcable unit structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent nests the dispense controller within the cable unit structure, placing the controller inside or along the cable that connects to the dispense head. This nesting approach consolidates multiple components into a compact arrangement, reducing device space while managing complexity through integrated cable assembly design that houses control electronics within the existing cable pathway

Inventive Principle:
Principle #7Nested doll (Nesting)
