Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If Cat.1bis terminal capability level is used for wearable devices, then cost is reduced and data throughput is improved, but downlink coverage capability deteriorates due to single receiving antenna loss

Engineering Contradiction:
Improvedata throughputVSAvoiddownlink coverage capability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic capability level selection where the wearable device can switch between different terminal capability levels (Cat.1bis, Cat.M1, Cat.M2, Non-BL Cat.1bis) based on real-time network conditions, coverage requirements, and data throughput needs. This dynamic adaptation resolves the contradiction by allowing the device to use Cat.1bis for high throughput when coverage is sufficient, and switch to coverage-enhanced modes when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the terminal by adjusting the capability level selection based on network version detection and coverage conditions. By modifying parameters such as receiving antenna configuration and modulation schemes according to network conditions, the system achieves both high data throughput and adequate coverage capability.

2Adaptability or versatility

If separate regional versions are released for different network deployments, then communication compatibility is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvecommunication compatibilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal terminal capability that can operate across multiple network versions (R10, R12, R13, R14, R15) and different capability levels. The wearable device contains a single unified implementation that can detect network version and adaptively select appropriate operating modes, eliminating the need for separate regional versions while maintaining broad communication compatibility.

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

Solution Approach 2:

The system dynamically detects the network version and adjusts operational parameters accordingly. The wearable device can automatically identify whether it's operating on R12, R13, R14, or R15 networks and switch between different terminal capability levels (Cat.1bis, Cat.M1, Cat.M2, Non-BL Cat.1bis) to maintain optimal compatibility without requiring multiple pre-configured regional versions.

Inventive Principle:

3Ease of manufacture

If low-network version solutions are released for all markets, then manufacturing cost is reduced, but user experience deteriorates in regions with high-network versions

Engineering Contradiction:

Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent enables dynamic adaptation where the wearable device automatically detects the network version and adjusts its operational capability level accordingly. In regions with R15 networks, the device can utilize Non-BL Cat.1bis or Cat.M2 for enhanced performance, while in R12 regions it falls back to Cat.1bis, thus maintaining good user experience across all markets without requiring different hardware versions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters based on network conditions, allowing a single unified device design to deliver optimized performance in different network environments. The device can adjust data throughput capabilities, coverage enhancement features, and antenna configurations according to the detected network version, ensuring satisfactory user experience whether deployed in R10, R12, R13, R14, or R15 regions.
