Solution Overview

Problem

Conventional microscopes require physical contact and manual handling for alignment, which can be cumbersome and limit user experience, especially in applications like surgical optical imaging systems where hands-on adjustments are not feasible.

Innovation Solution

An optical imaging system apparatus that uses control data derived from user hand movements relative to a visual representation of an axis to facilitate contactless alignment and adjustment of microscope parameters such as observation angle, magnification, and field of view, utilizing processors and sensors to determine and transmit axis, movement, and gesture data for intuitive control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If physical contact and manual handling are used for microscope alignment, then the alignment can be performed with simple mechanical controls, but the operation becomes cumbersome and limits user experience

Engineering Contradiction:
Improveease of microscope alignmentVSAvoidcomplexity of control system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical handling system with a gesture recognition system. Sensors detect hand movements and gestures in three-dimensional space, converting physical gestures into control signals for microscope alignment. This substitution eliminates the need for physical contact with mechanical controls while maintaining alignment functionality, directly resolving the contradiction between ease of operation and device complexity.

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

Solution Approach 2:

The patent introduces gesture recognition technology as an intermediary between the user and the microscope alignment system. The system captures hand movements through sensors, processes them through gesture recognition algorithms, and translates them into alignment commands. This intermediary layer provides an intuitive control interface that improves ease of operation without requiring complex direct mechanical manipulation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If physical contact with the microscope is required for alignment, then the control mechanism remains simple, but hands-free operation becomes impossible

Engineering Contradiction:
Improvehands-free operation capabilityVSAvoidease of microscope control
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical contact-based control with a gesture recognition system that detects hand movements in three-dimensional space. Sensors capture gestures without requiring physical contact with the microscope, enabling hands-free operation while maintaining intuitive control. This substitution directly enables hands-free operation capability without sacrificing ease of operation.

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

Solution Approach 2:

The system allows the user's natural hand gestures to directly control the microscope alignment without requiring learning of complex mechanical interfaces. The gesture recognition system interprets intuitive movements, making the system self-adapting to natural user behavior, thereby improving both hands-free operation capability and ease of operation.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If gesture recognition and sensor data integration are implemented, then hands-free operation and multi-user support are enabled, but the system complexity increases

Engineering Contradiction:
Improvemulti-user support capabilityVSAvoidcomplexity of sensor integration system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gesture recognition system serves multiple functions: it enables hands-free operation, supports multiple users through recognition of different gesture patterns, and provides intuitive control for various microscope operations. This multi-functionality approach allows a single sensor integration system to achieve adaptability and versatility without requiring separate systems for each function, thereby managing complexity while enhancing multi-user support capability.

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