Solution Overview

Problem

Existing wireless positioning technologies face issues such as positioning signal coverage gaps due to inconsistencies between antenna performance and environmental conditions, leading to inaccurate azimuth measurements and prolonged positioning times.

Innovation Solution

Incorporating auxiliary determining units in wireless positioning modules with optical angles less than or equal to signal coverage angles, allowing for quick determination of effective positioning data by analyzing auxiliary determining signals to identify abnormal signal areas and adjust positioning strategies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If auxiliary determining units are added to each signal area, then positioning accuracy and success rate are improved, but device complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the signal coverage area into multiple signal areas, with each area containing an auxiliary determining unit. This segmentation allows each unit to independently determine positioning effectiveness in its specific area, improving overall positioning accuracy without requiring every unit to process all data.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The auxiliary determining unit acts as an intermediary component that receives positioning data from the wireless positioning module and determines its effectiveness. This mediator approach allows the main positioning system to remain simple while adding specialized units only where needed for verification.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If auxiliary determining units are added to each signal area, then positioning success rate is improved, but manufacturing cost increases

Engineering Contradiction:
Improvepositioning success rateVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The auxiliary determining unit is designed as a simple, low-cost component with relatively basic processing capabilities. By using inexpensive hardware and software-based determination logic, the patent achieves high positioning success rates without significant cost increases, making the solution economically viable.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Device complexity

If positioning data is processed without auxiliary determination, then device complexity is reduced, but positioning time increases

Engineering Contradiction:
Improvedevice complexityVSAvoidpositioning time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The auxiliary determining unit performs preliminary determination of positioning data effectiveness before the main positioning processing begins. This preliminary action filters out ineffective data early, preventing time-consuming processing of useless information and reducing overall positioning time despite the added component.

Inventive Principle:
Principle #10Preliminary action
