Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing secondary batteries used in mobile terminals are limited by their cylindrical, square, or pouch shapes, which restrict their application in various portable device designs due to the need for a separate space, hindering the development of devices with diverse shapes.
Innovation Solution
A mobile terminal equipped with an earphone port that can accept a cable-type battery, allowing the battery to charge the terminal and function as both an auxiliary power source and an audio output path, enabling flexible shape integration and user-controlled audio output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional secondary batteries (cylinder, square, or pouch shape) are used in mobile terminals, then they can provide power supply function, but they require separate space and limit the development of portable devices with various shapes
Solution Approach 1:
The patent combines the battery and earphone into a single integrated device. The battery is placed inside the earphone housing, merging two previously separate components (power supply and audio output) into one unified structure. This eliminates the need for separate battery space while maintaining both functions simultaneously.
Solution Approach 2:
The earphone is designed to serve multiple functions: it acts as both an audio output device and a power supply source. The cable-type battery within the earphone can charge the mobile terminal while the earphone simultaneously provides audio output, making the device universal and adaptable to various usage scenarios.
2Adaptability or versatility
If earphone with cable-type battery is inserted into earphone port, then it can charge the power supply unit and provide audio output, but the mobile terminal needs to select between multiple audio output paths
Solution Approach 1:
The mobile terminal automatically detects whether the inserted earphone contains a cable-type battery and autonomously determines the appropriate audio output path without requiring manual user selection. The controller identifies the earphone's dual functionality and automatically configures the audio routing, reducing control complexity while maintaining flexibility.
3Ease of manufacture
If secondary batteries are fabricated in fixed shapes (cylinder, square, pouch), then they can be manufactured using standard processes, but they become an obstacle for development of portable devices of various shapes
Solution Approach 1:
The battery is nested within the earphone housing structure. This nested arrangement allows the battery to adopt the shape of the earphone case rather than requiring a separate fixed shape, enabling portable devices to have diverse external shapes while using standardized battery manufacturing processes inside the constrained earphone form factor.
