Solution Overview

Problem

Existing remote identifier technologies face challenges in accurately selecting a specific product from multiple tagged items due to the wide wavelength of microwave signals, leading to cumbersome user interfaces and memory overload in devices like mobile phones when trying to control or read data from nearby products.

Innovation Solution

The solution involves using a reader that either brings the reader close to the tag or uses a secondary optical signal, such as infrared or visible light, synchronized with the radio frequency to selectively activate desired remote identifiers, allowing for precise selection and control of products or devices using a mobile station as a reader.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If microwave radio frequency signals are used for remote identification, then reading distance can be several meters, but the long wavelength causes inability to selectively aim at specific products among multiple tagged items

Engineering Contradiction:
Improvereading distanceVSAvoidproduct selection precision
Core Design Contradiction:
Length of stationary objectVSMeasurement precision

Solution Approach 1:

The patent divides the selection process into two independent stages: first using microwave RF signals for long-distance reading, then using optical signals (laser/infrared) for precise spatial selection. This segmentation allows each signal type to optimize for its specific function without compromise.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces optical signals as an intermediary mechanism between the microwave RF reader and the target product. The optical signal serves as a mediator that provides directional precision while the RF signal handles the wireless communication, resolving the contradiction between range and precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If all nearby products are read and data is stored in mobile telephone memory, then product data can be accessed, but memory space is consumed and user interface becomes cumbersome

Engineering Contradiction:
Improveproduct control capabilityVSAvoidmemory usage
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent extracts the product selection function from the mobile telephone's memory system. Instead of storing data from all nearby products in phone memory, the system uses optical targeting to extract and select only the specific product needed, eliminating the need for extensive memory usage.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system enables self-service selection where the user simply points the device at the desired product, and the system automatically identifies and activates only that specific product's data transmission, without requiring manual navigation through stored product lists.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If menu-based selection is used to control products, then specific products can be selected, but operation becomes laborious and time-consuming

Engineering Contradiction:
Improveproduct selection easeVSAvoidselection time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical menu navigation system with an optical pointing mechanism. Instead of manually navigating menus to select products, users simply point the device at the target product, and the optical signal automatically identifies it, substituting mechanical interaction with optical targeting.

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

Solution Approach 2:

The system performs preliminary optical targeting and identification before data transmission begins. By pre-selecting the target product through optical pointing, the system eliminates the need for subsequent menu navigation, saving time and effort.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If multiple remote identifiers are within reading range, then data from any product can be read, but it becomes difficult to distinguish and select the desired product

Engineering Contradiction:
Improvereading capabilityVSAvoidproduct distinction difficulty
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies local quality by using optical signals with specific spatial characteristics (directionality, focus) to create a localized reading zone. This allows the system to maintain broad RF reading capability while adding local optical precision to distinguish between multiple nearby identifiers based on their spatial position.

Inventive Principle:
Principle #3Local quality
