Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed assignment of measurement channels to connections is used, then device structure is simple, but flexibility in connecting measurement objects is reduced and complex cabling is required

Engineering Contradiction:
Improveflexibility in connecting measurement objectsVSAvoidcomplex cabling
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic assignment of measurement channels to connections through software control. The control device can reassign channels to connections based on the measurement task, allowing the same physical connection to serve different measurement functions. This eliminates the need for complex cabling configurations while maintaining measurement flexibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Each connection is designed to be multi-functional, capable of being assigned to different measurement channels depending on the task requirements. The control device enables a single connection to serve multiple measurement purposes by dynamically switching channel assignments, reducing the need for dedicated cabling for each measurement type.

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

2Ease of operation

If fixed assignment of measurement channels is used, then channel allocation is simple, but operational effort and complexity increase for users

Engineering Contradiction:
Improveease of connecting measurement objectsVSAvoidoperational effort
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The control device automatically manages channel assignment based on the selected measurement task. When a user selects a measurement task, the system automatically assigns appropriate channels to connections without requiring manual configuration. This self-service approach reduces operational effort and eliminates time-consuming manual channel assignment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-configures channel assignments based on selected measurement tasks. Before the user needs to perform a measurement, the control device has already assigned the appropriate channels to connections based on the task requirements, eliminating the need for users to manually configure channels and reducing operational time.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If display devices are placed close to connections, then assignment clarity is improved, but device manufacturing complexity increases

Engineering Contradiction:
Improveintuitiveness of channel assignment displayVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines display devices with the connection interfaces, integrating the display function directly into the connection area. This merging of display and connection functions provides clear visual feedback about channel assignments close to the connection points while using space-efficient integrated design that manages manufacturing complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A measuring instrument comprises a control device, at least two terminals (6, 7, 8, 9), at least two measuring channels, and at least two display devices (10a, 11a, 12a, 13a). The control device allocates terminals (6, 7, 8, 9) to the measuring channels and internally connects the measuring channels at least in a logical manner to said terminals (6, 7, 8, 9), a display device (10a, 11a, 12a, 13a) being associated with each terminal (6, 7, 8, 9). The display devices (10a, 11a, 12a, 13a) associated with the terminals (6, 7, 8, 9) display information that relates to the current allocation and/or utilization of the terminals (6, 7, 8, 9).
