Solution Overview

Problem

Current display manufacturing apparatuses require separate stations for transferring, inspecting, and mending miniature light emitting diodes, leading to inefficiencies due to long conveying distances and times, resulting in delayed inspection and mending processes.

Innovation Solution

Integration of transferring, inspecting, and mending processes on a single apparatus with a working platform, conveying paths, and movable stations for efficient handling and welding of miniature light emitting diodes, including a transferring station, defect inspecting station, and mending station, which reduces conveying distance and time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If separate stations for transferring, inspecting, and mending are used, then each process can be performed independently, but the conveying distance and time increase, resulting in reduced productivity

Engineering Contradiction:
Improveproduction efficiencyVSAvoidconveying time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines multiple independent manufacturing stations (transferring, inspecting, and mending stations) into a single integrated apparatus. The transferring gantry, inspecting gantry, and mending gantry are all disposed on the same working platform and share common conveying paths and carriers, enabling seamless integration of processes without intermediate conveying steps between separate apparatuses.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The working platform serves multiple functions by accommodating different types of gantries (transferring, inspecting, mending) that can operate on the same conveying paths. The carriers are universally designed to handle display substrates through all three processes, and the control system coordinates all stations to work harmoniously as a unified system.

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

2Productivity

If separate manufacturing apparatuses are used for transferring, inspecting, and mending, then each process can be optimized independently, but the factory space required increases

Engineering Contradiction:
Improveprocess optimizationVSAvoidfactory space
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent consolidates multiple manufacturing functions into a single apparatus located on one working platform. The transferring station, defect inspecting station, and mending station all share the same physical space and infrastructure, eliminating the need for separate factory areas for each process and reducing overall facility requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent utilizes vertical space by employing gantry systems that move overhead on the working platform. The transferring gantry, inspecting gantry, and mending gantry operate in the vertical dimension above the conveying paths, allowing multiple processes to occupy the same horizontal footprint without interfering with each other.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If display substrates are conveyed between separate stations, then each process can be performed by specialized equipment, but waiting time in line increases

Engineering Contradiction:
Improveprocess qualityVSAvoidwaiting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The integrated apparatus enables continuous processing where display substrates move seamlessly from the transferring station to the inspecting station and then to the mending station without interruption or waiting. The shared conveying paths and coordinated gantry operations ensure that each process can begin immediately upon the substrate's arrival, eliminating idle time and maintaining continuous production flow.

Inventive Principle:
Principle #20Continuity of useful action
