Solution Overview

Problem

Current eye examination devices lack interoperability between different manufacturers and models, requiring practitioners to equip themselves exclusively with devices from a single manufacturer, leading to limitations in device replacement, user interface variability, and restricted access to diagnostic aids and third-party enhancements.

Innovation Solution

A modular control system that enables communication and interoperability between eye examination devices from various manufacturers by using a modular box with protocol management cards to convert physical protocols and a control box with a graphic and technical interface to translate human logic language into machine logic language, allowing devices to communicate and function seamlessly regardless of manufacturer or model.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If devices from different manufacturers are used, then device choice and flexibility improve, but interoperability and communication compatibility deteriorate

Engineering Contradiction:
Improvedevice choiceVSAvoidinteroperability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a control system as an intermediary device that mediates communication between eye examination devices from different manufacturers. The control system includes a control unit with a communication interface that can translate and manage data exchange between incompatible devices, allowing practitioners to use devices from various manufacturers while maintaining reliable interoperability through the mediating control system.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The control system is designed with universal functionality to work with multiple types of eye examination devices from different manufacturers. The communication interface can handle various data formats and protocols, enabling a single control system to manage diverse devices including autorefractometers, focimeters, and patient management software, thereby providing versatility without sacrificing compatibility.

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

2Ease of operation

If proprietary control consoles are used, then device-specific control precision improves, but system flexibility and manufacturer independence deteriorate

Engineering Contradiction:
Improvedevice controlVSAvoidmanufacturer independence
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The control system acts as an intermediary between the user interface and manufacturer-specific devices. It provides a standardized control interface that translates user commands into device-specific protocols, maintaining ease of operation while enabling manufacturer independence. The control unit can adapt to different device types without requiring proprietary control consoles for each manufacturer.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system separates the control function from the device-specific communication functions. The control unit handles high-level control logic and user interaction, while communication with individual devices is handled through standardized interfaces. This segmentation allows the control system to maintain ease of operation while being independent of any single manufacturer's proprietary control console design.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If manual data transfer between devices is used, then device simplicity improves, but time consumption and error probability increase

Engineering Contradiction:
Improvedevice designVSAvoiddata transfer time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The control system serves as an intermediary that automatically manages data transfer between eye examination devices. It receives data from devices such as autorefractometers and focimeters, processes it, and transmits it to patient management software or other devices, eliminating manual data entry. This automated intermediary approach maintains simple device designs while dramatically reducing data transfer time and error probability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The control system enables devices to communicate and transfer data automatically without human intervention. The control unit manages the entire data flow between devices, including format conversion and protocol adaptation, allowing the system to serve itself rather than requiring practitioners to manually transfer data between devices.

Inventive Principle:
Principle #25Self-service

4Device complexity

If thermal printers are used for result output, then device simplicity improves, but information transfer efficiency and accuracy deteriorate

Engineering Contradiction:
Improveoutput deviceVSAvoiddata transfer accuracy
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The control system acts as an intermediary between measurement devices and output devices. Instead of relying on simple thermal printers that require manual transcription, the control unit automatically receives digital data from measurement devices, processes it, and transmits it directly to patient management software or display devices, eliminating information loss associated with manual transfer while keeping the overall system architecture simple.

Inventive Principle:
Principle #24Intermediary (Mediator)
