Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If automated inspection devices with rigid connecting means are used, then inspection accuracy is improved, but device flexibility and adaptability to complex geometries deteriorate

Engineering Contradiction:
Improveinspection accuracyVSAvoiddevice flexibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent employs a robotic arm with multiple degrees of freedom that can dynamically adjust its position and orientation to adapt to various wing profile geometries. The robotic arm replaces rigid connecting means, allowing the inspection device to flexibly accommodate complex shapes while maintaining measurement precision through controlled positioning.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The inspection apparatus is designed with a universal robotic positioning system that can handle multiple wing profile types and configurations. The robotic arm serves multiple functions: positioning, orientation adjustment, and adaptation to different geometries, making the device versatile for various inspection scenarios without requiring specialized equipment for each geometry type.

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

2Device complexity

If manual inspection methods are used, then device simplicity is maintained, but inspection time and operator subjectivity increase

Engineering Contradiction:
Improvedevice simplicityVSAvoidinspection time
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The robotic inspection system performs automated inspection operations without requiring manual manipulation by operators. The robotic arm autonomously positions itself, executes measurement sequences, and collects data, eliminating the time-consuming and subjective aspects of manual inspection while maintaining relatively simple device architecture.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical inspection operations with an automated robotic system. The robotic arm uses controlled mechanical movement guided by programming rather than human operators, significantly reducing inspection time and eliminating subjectivity while keeping the overall device structure relatively simple.

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

3Ease of operation

If inspection devices are made portable and lightweight, then ease of transport is improved, but device weight and structural stability deteriorate

Engineering Contradiction:
Improveease of transportVSAvoiddevice weight
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The inspection apparatus is divided into modular segments: a base unit, a robotic arm assembly, and a detection module. This segmentation allows the device to be broken down into transportable components while maintaining structural stability during operation. Each segment can be optimized for weight reduction without compromising overall functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs thin-walled but structurally adequate components in the robotic arm and housing, optimizing the weight-to-strength ratio. The use of lightweight materials and thin-walled structures reduces device weight for improved portability while maintaining sufficient structural stability during inspection operations.

Inventive Principle:
Principle #30Flexible shells and thin films

4Stability of the object's composition

If rigid connecting means are used to fix the inspection device, then measurement stability is improved, but measurement interference and stress on the element increase

Engineering Contradiction:
Improvemeasurement stabilityVSAvoidmeasurement interference
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The robotic arm serves as an intermediary between the operator and the inspection device, providing stable positioning without direct rigid fixation to the element being inspected. This intermediary mechanism maintains measurement stability through controlled robotic positioning while avoiding the harmful effects of rigid fixation, such as stress induction and measurement interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention concerns an apparatus (100) for non-destructive inspection of structural elements (10) having a wing profile, comprising a base (20), a positioning module (300) associated with the base (20) in correspondence with its own first end portion (310) and a detection module (400) associated with a second end portion (320) of the positioning module (300) and comprising a support frame to which at least one impulse hammer (43) and at least one first microphone (44') of the piezoelectric type are connected. The support frame comprises at least a first arm (41) to which a first regulation unit (45) is associated, adapted to support the impulse hammer (43) and to regulate a movement thereof along the first arm (41) itself and a second arm (42) to which a second regulation unit (46) is associated, adapted to support the first microphone (44') and to regulate a movement thereof along the second arm (42) itself. The first arm (41) and the second arm (42) are arranged facing each other and spaced apart, so as to define a working volume suitable for accommodating a structural element (10) having a wing profile, said first arm (41) and second arm (42) being connected to each other by means of a connecting element (47) which allows their reciprocal movement.
