Innovation Solution

A device comprising an imaging sensor unit mounted on a crane, a crane state determination system, and an electronic computing unit that processes images and crane states to form context-sensitive tuples for holistic documentation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual documentation methods are used, then simplicity is maintained, but comprehensiveness and continuity of documentation deteriorate

Engineering Contradiction:
Improvedocumentation systemVSAvoidconstruction site information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent replaces manual mechanical documentation processes with an automated sensor-based system. Imaging sensors, crane state determination devices, and electronic computing units automatically capture and process construction site data, eliminating the need for manual observation and recording while ensuring comprehensive and continuous documentation.

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

Solution Approach 2:

The documentation system operates autonomously by self-capturing construction site images through imaging sensors, self-determining crane states through dedicated devices, and self-processing data through electronic computing units. The system serves itself without requiring continuous manual intervention, thereby maintaining simplicity while achieving comprehensiveness.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple parties document independently, then individual perspectives are captured, but duplication of work and fragmentation increase

Engineering Contradiction:
Improvedocumentation coverageVSAvoiddocumentation efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent merges multiple documentation functions into a single integrated system. The imaging sensor unit, crane state determination device, and electronic computing unit work together as a unified system, consolidating what would otherwise be separate documentation efforts into one coordinated approach that eliminates duplication while maintaining comprehensive coverage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated documentation system performs multiple functions simultaneously: capturing construction site images, determining crane states, processing data, and generating comprehensive documentation. This multi-functional approach replaces the need for multiple separate parties to document independently, improving productivity while maintaining versatility.

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

3Loss of information

If comprehensive documentation is achieved through manual effort, then information completeness improves, but maintenance effort and time consumption increase

Engineering Contradiction:
Improveconstruction site informationVSAvoiddocumentation time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent implements continuous automated documentation through the imaging sensor unit and crane state determination device, which operate continuously without interruption. This ensures comprehensive information capture while eliminating the time-consuming manual processes of repeatedly observing, recording, and updating documentation, as the system performs all functions automatically and continuously.

Inventive Principle:
Principle #20Continuity of useful action

4Loss of information

If automated sensor systems are deployed, then documentation comprehensiveness improves, but device complexity increases

Engineering Contradiction:
Improveconstruction site informationVSAvoidsensor system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the automated documentation system into distinct functional modules: the imaging sensor unit for image capture, the crane state determination device for state detection, and the electronic computing unit for data processing. This segmentation allows each component to perform its specific function independently, reducing the perceived complexity while achieving comprehensive documentation through coordinated operation of simplified individual elements.

Inventive Principle:
Principle #1Segmentation
