Wireless Earphone Charger Indicator Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless earphone chargers with multiple light emitters struggle to provide clear and recognizable indications of battery power levels and charging states, leading to decreased visibility and design quality.
Innovation Solution
A wireless earphone charger with a receiving circuit, an earphone rechargeable battery, an indicator, and a controller that switches between indication modes to clearly show the remaining power of the rechargeable battery and the earphone battery, using a combination of light emission patterns and colors to differentiate between states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple light emitters emit light simultaneously in multiple colors to indicate both rechargeable battery power and earphone rechargeable battery power, then the user can recognize both power states, but the visibility and design of the indicator deteriorates and the user cannot instantly recognize the information
Solution Approach 1:
The patent divides the indicator function into two separate indicators: one dedicated to displaying the rechargeable battery power level and another for the earphone rechargeable battery power level. Each indicator uses a single color light emitter, avoiding the confusion of multiple colors emitting simultaneously. This segmentation allows users to instantly recognize each power state without visual interference, resolving the contradiction between providing complete information and maintaining clear visibility.
2Loss of information
If multiple light emitters are used to display both battery and earphone battery remaining power, then comprehensive power information is provided, but the design quality and visibility of the indicator is reduced
Solution Approach 1:
The patent implements separate indicator structures for displaying battery power information and earphone battery power information. Each indicator has its own dedicated light emitter and display elements, preventing design complexity from accumulating in a single indicator. This segmentation maintains aesthetic quality while providing complete power information through two simple, clean indicators rather than one complex multi-color indicator.
Solution Approach 2:
The patent combines the functions of multiple light emitters into a unified indicator system where each indicator integrates its light emitter with the display elements in a coordinated manner. The indicators are positioned and designed to work together as a cohesive visual information system, reducing overall design complexity compared to having separate, independent multi-color light emitter assemblies.
