Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual configuration is used for setting up sensor devices, then installation workers can directly input data, but errors increase and efficiency decreases due to small labels and long unique IDs

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidinstallation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces manual mechanical input (typing long unique IDs from small labels) with automated optical scanning (QR code/barcode reading). The mobile computing device captures images of codes on sensor devices and automatically extracts identification information, eliminating manual transcription errors and significantly improving both accuracy and installation speed

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

Solution Approach 2:

The patent uses visual copies (QR codes or barcodes) of sensor device identification information that can be rapidly scanned and captured by the mobile computing device. These codes serve as machine-readable replicas of the unique IDs, enabling automatic data retrieval without manual reading and typing, thus improving both reliability and productivity

Inventive Principle:
Principle #26Copying

2Productivity

If automated installation is implemented, then installation efficiency increases, but device complexity increases due to integration of mobile computing device and communication protocols

Engineering Contradiction:
Improveinstallation speedVSAvoidsystem integration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mobile computing device performs multiple functions: capturing images of QR codes/barcodes, processing image data to extract identification information, obtaining location data, and communicating with the server. By consolidating these functions into a single existing device rather than requiring specialized equipment, the system achieves automation without proportionally increasing complexity

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

Solution Approach 2:

The patent introduces a server as an intermediary that receives installation information from mobile computing devices and manages the central database. This mediator handles the complexity of data aggregation, association, and storage, allowing the mobile device itself to remain relatively simple while achieving sophisticated automated installation capabilities

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If manual association of sensor device IDs with locations is performed, then system simplicity is maintained, but time consumption increases significantly in large-scale installations

Engineering Contradiction:
Improveconfiguration simplicityVSAvoidinstallation time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical process of looking up and typing location information with automated image recognition and data extraction. The mobile computing device automatically reads QR codes/barcodes, extracts identification information, retrieves location data, and performs associations without manual intervention, dramatically reducing installation time while keeping the underlying system simple

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

Solution Approach 2:

The patent implements preliminary action by pre-associating QR codes or barcodes with sensor device identification information and location data before installation. This preparation allows the mobile computing device to automatically retrieve and process information during installation without requiring manual lookup or data entry, saving significant time in large-scale deployments

Inventive Principle:
Principle #10Preliminary action
