Solution Overview

Problem

Existing devices for controlling microscope settings require users to unintuitively set numerous parameters without recognizing interdependencies, leading to inefficient and potentially harmful combinations.

Innovation Solution

A graphical user interface allows simultaneous adjustment of at least three setting parameters, with at least two being independent, by positioning an input pointer within an input area, where parameter values are determined based on the distance from coordinate origins, enabling intuitive and interdependent parameter adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional control units with numerous buttons and control pads are used, then multiple parameters can be set, but the operation becomes unintuitive and complex

Engineering Contradiction:
ImproveParameter setting intuitivenessVSAvoidControl unit structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent transforms the control interface from a one-dimensional array of buttons to a two-dimensional graphical user interface where parameters are adjusted by positioning a pointer within a display area. This dimensional change allows multiple parameters to be controlled simultaneously through spatial position rather than sequential button presses, making the operation more intuitive while reducing the perceived complexity of the control structure.

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

Solution Approach 2:

The patent introduces a graphical user interface as an intermediary between the user and the control unit's internal parameters. This intermediary layer translates intuitive graphical interactions (pointer positioning, clicking) into the actual parameter settings, hiding the complexity of the underlying control mechanisms while providing ease of operation at the user interface level.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple parameters are set independently, then flexibility is increased, but harmful combinations of parameters may occur

Engineering Contradiction:
ImproveParameter adjustment flexibilityVSAvoidTissue damage from unsafe parameter combinations
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements feedback mechanisms where the system continuously monitors the combination of selected parameters and provides information about their safety and compatibility. The graphical interface can display relationships between parameters, warn about potentially harmful combinations, and guide users toward safe parameter settings, thus maintaining flexibility while preventing harmful effects.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system applies preliminary anti-action by pre-defining safe parameter combinations and preventing the selection of harmful combinations before they can cause damage. The graphical user interface is designed to guide users toward safe operating ranges and block or warn against parameter combinations that could lead to tissue damage, thereby counteracting potential harm before it occurs.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

The invention relates to a computer-implemented method for determining a value for each of at least three setting parameters by means of an input unit (100) in the form of a graphical user interface with an input cursor (120) which can be positioned in an input area (110), wherein at least two of the at least three setting parameters can be set independently of one another, which method comprises: determining a position of the input cursor (120) within the input area (110), determining a coordinate (x, y, z) of the position of the input cursor (120) for each of the at least three setting parameters as a function of a distance of the position in each case of the input cursor (120) from at least one coordinate origin (130, 140, 150) allocated to the particular setting parameter, and determining a value for each of the at least three setting parameters as a function of the coordinate (x, y, z) determined for said setting parameters. The invention also relates to a computing unit, a computer program and a system for implementing the method.
