Solution Overview

Problem

Existing handsfree apparatuses struggle to respond to model-dependent constraints of newer phone models, as their databases cannot memorize information for phones sold after the apparatus's release, leading to operational issues and user burden.

Innovation Solution

Incorporating a storage medium with a primary control program and a model-specific program that retrieves and executes model-specific programs based on acquired phone model and program specification information, allowing the apparatus to adapt to unknown phone models by associating phone model information with program specification information and updating device names to include necessary keywords.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a database is built to memorize phone model information and corresponding faults, then the handsfree apparatus can respond to known phone models, but the database cannot memorize information for phones put on sale after the apparatus was put on sale

Engineering Contradiction:

Improveresponse accuracy to phone model constraintsVSAvoidcompatibility with new phone models

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic database structure that can be updated with new phone model information. The system allows the database to grow and adapt over time by incorporating new phone models and their specific constraints, transforming the static database into a dynamic one that evolves with new phone releases.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent creates a universal database structure that can accommodate multiple phone models and their various constraints. The database is designed to store diverse information about different phone models, manufacturers, and specific faults, making it applicable to a wide range of scenarios rather than being limited to specific models.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If the handsfree apparatus uses a fixed database of phone models, then it can operate optimally with known models, but it cannot respond to faults of newer phone models

Engineering Contradiction:

Improveoperational efficiency with known modelsVSAvoidfault response capability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements preliminary action by pre-building a comprehensive database structure that anticipates future phone models. The system prepares the framework in advance to accommodate new models, so when new phones are released, the handsfree apparatus can quickly integrate them without starting from scratch.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent incorporates feedback mechanisms that allow the system to learn from new phone models. When a new phone model is connected, the system can acquire its information, store it in the database, and use this feedback for future operations, continuously improving its fault response capability.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If the handsfree apparatus acquires phone model information from the phone, then it can identify the connected phone, but it cannot retrieve model-specific programs when the model information is not included in the database

Engineering Contradiction:

Improvephone model identification accuracyVSAvoidprogram retrieval capability

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent introduces an intermediary mechanism - the program acquisition means - that bridges the gap between phone model identification and program execution. This intermediary can retrieve model-specific programs from external sources or the phone itself when the database lacks information, facilitating program retrieval for unknown models.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent expands the system's capability by adding another dimension - external program acquisition channels. Instead of relying solely on the internal database, the system can access programs from external sources such as information centers or the phone itself, creating a multi-dimensional program retrieval architecture.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A handsfree system includes a handsfree apparatus and a phone. The handsfree apparatus has a database including a primary control program and a model-specific program. The primary control program enables the handsfree phone call when coupled with the phone. The model-specific program is operated to resolve a model-dependent constraint by being incorporated in the primary control program. The model-dependent constraint arises when coupled with the phone. The model-specific program is associated with phone model information and program specification information to specify the model-specific program independent of the phone model information. Phone model information and program specification information are acquired from a phone coupled with the handsfree apparatus. Model-specific program corresponding to the acquired program specification information is retrieved from the database when the acquired phone model information is not included in the database. The retrieved model-specific program is executed by incorporating in the primary control program.
