Solution Overview

Problem

Handheld electronic devices face challenges in identifying and optimizing settings for various components, such as audio headsets, due to the lack of a reliable method to differentiate and adjust settings based on the inserted component's characteristics, leading to suboptimal user experience.

Innovation Solution

The system employs a light source and light sensor within the device to emit light into a receiving socket, detecting the reflected light's amplitude, wavelength, and intensity from the component's connector, which is used to identify the component and adjust settings like treble, bass, and mid-range levels based on stored profiles, ensuring optimal performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If visual inspection methods are used to identify components, then the system complexity is reduced, but the identification accuracy and reliability are insufficient

Engineering Contradiction:
Improvecomponent identification accuracyVSAvoiddetection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual visual inspection with an automated optical detection system using LEDs and photodetectors to read component identifiers. This substitution of mechanical/visual methods with optical sensing achieves accurate automated identification while keeping the system relatively simple through use of basic optical components rather than complex imaging systems.

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

Solution Approach 2:

The component connector includes an integrated identifier (such as a reflective surface or optical code) that automatically provides identification information when a component is inserted. The detection system simply needs to read this self-provided identifier, eliminating the need for complex active signaling from the component while achieving reliable identification.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If a simple connector design is used, then the ease of manufacture is improved, but the ability to identify and differentiate components is reduced

Engineering Contradiction:
Improvecomponent differentiation capabilityVSAvoidconnector manufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies local quality by adding specific optical characteristics (such as reflective surfaces, colored coatings, or localized patterns) to specific regions of the connector. This allows different component types to be differentiated through localized modifications rather than redesigning the entire connector, maintaining manufacturing simplicity while achieving component differentiation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses color or optical property variations on the connector surface (such as different reflective properties, absorptive coatings, or colored rings) to encode component identity information. These visual markers can be applied through simple manufacturing processes like painting or anodizing, enabling component differentiation without adding mechanical complexity.

Inventive Principle:
Principle #32Color changes
