Solution Overview

Problem

Existing NFC technologies face inefficiencies in large-size or large-area products due to high power consumption and increased production costs when multiple NFC chips and antennas are used, and inefficiencies in data interaction when a single NFC chip matches multiple antennas.

Innovation Solution

A data interaction apparatus with an interaction module, switch module, positioning module, and drive module, where the positioning module generates positioning information to determine a target interaction unit and switch unit, allowing the drive module to efficiently interact with the interaction object without turning on all units simultaneously, reducing power consumption and production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple NFC chips and antennas are used in large-size products, then data interaction capability is improved, but power consumption increases

Engineering Contradiction:

Improvedata interaction capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The interaction module is divided into multiple interaction units (first interaction unit, second interaction unit, etc.), each capable of independent data interaction. The drive module selectively activates only the necessary interaction units based on positioning information, avoiding the need to power all units simultaneously. This segmentation enables the system to maintain multi-point interaction capability while reducing power consumption by activating only 1-3 units at a time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts which interaction units are activated based on real-time positioning information of interaction objects. The control module determines target interaction units and controls the switch module to connect only those units to the drive module, creating a dynamic power management system that adapts to actual interaction needs rather than maintaining static full-power operation.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple NFC chips and antennas are used in large-size products, then data interaction capability is improved, but production cost increases

Engineering Contradiction:

Improvedata interaction capabilityVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

A single drive module is designed to control multiple interaction units through the switch module, making the drive module universal and multi-functional. This allows the system to achieve multi-point interaction capability without proportionally increasing the number of drive modules, thereby reducing production costs while maintaining enhanced data interaction capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple interaction units are merged under the control of a single drive module via the switch module. The switch module acts as an intermediary that combines the control signals from one drive module and distributes them to multiple interaction units, reducing the total component count and production complexity compared to using separate drive modules for each interaction unit.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If a single NFC chip matches multiple antennas, then production cost is reduced, but data interaction efficiency decreases

Engineering Contradiction:

Improveproduction costVSAvoiddata interaction efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The system segments the interaction process into positioning (by positioning module), target identification (by control module), and data interaction (by drive module with selected interaction units). This segmentation allows the single NFC chip to efficiently manage multiple antennas by activating only the specific interaction unit corresponding to the positioned object, rather than sequentially polling all units, thereby improving interaction speed and efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning module provides feedback information about interaction object positions to the control module, which then determines the target interaction unit. This feedback mechanism enables the system to quickly identify and activate the correct interaction unit without trial-and-error polling, significantly improving data interaction efficiency while maintaining cost-effectiveness through single-chip architecture.
