Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If RFID tags are embedded in the sheet to enable automatic fold detection, then digitization efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvedigitization efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The sheet itself performs the detection function through embedded RFID tags that automatically sense fold occurrences and transmit data, eliminating the need for external sensors and manual input devices. The sheet serves both as the work material and the sensing medium.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mechanical system of manual fold tracking and digital input is replaced with an electromagnetic field-based RFID system that automatically detects and records fold events through radio frequency communication between tags and readers.

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

2Measurement precision

If RFID tags are embedded in the sheet to monitor folding in real-time, then measurement precision is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvefold detection accuracyVSAvoidsheet processing complexity
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The RFID tags are integrated directly into the sheet material during manufacturing, merging the sensing function with the base material. This combination simplifies the overall system by eliminating separate sensor components and reduces assembly steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sheet serves multiple functions: it is both the work material being folded and the sensing medium that detects and records fold events. The RFID tags enable the sheet to simultaneously perform structural and measurement functions.

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

3Loss of information

If an array of RFID tags is used to track fold properties, then information completeness is improved, but loss of substance increases

Engineering Contradiction:
Improvefold data completenessVSAvoidmaterial consumption
Core Design Contradiction:
Loss of informationVSLoss of substance

Solution Approach 1:

The sheet is divided into multiple segments with RFID tags distributed across different locations. Each tag monitors local fold events, and the collective data from all tags provides comprehensive information about the entire folding process, enabling precise tracking of complex multi-step folds.

Inventive Principle:
Principle #1Segmentation
