Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing aerosol delivery devices lack effective means to indicate the charge status of their power sources without requiring device activation or causing light pollution, and their assembly process is complex and time-consuming.

Innovation Solution

Incorporating a movement detection unit and feedback element to provide charge status feedback based on device movement, and using a connector pin design with biased heads for reliable electrical connections to simplify assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a feedback element is configured to provide continuous visual feedback during charging, then users can easily check battery level, but light pollution occurs during overnight charging

Engineering Contradiction:

Improvebattery level indicationVSAvoidlight pollution

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The feedback element provides visual feedback periodically only when movement is detected, rather than continuously during charging. This allows users to check battery level on demand by moving the device, while avoiding light pollution during overnight charging when the device is stationary.

Inventive Principle:

Principle #19Periodic action

2Ease of operation

If traditional button activation is required to check battery level, then device operation is simplified, but user convenience is reduced when device is not in use

Engineering Contradiction:

Improvebattery level checkingVSAvoiduser interaction time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The device automatically detects user movement via the movement detection unit and provides battery level feedback without requiring the user to press buttons or activate the device. The system serves itself by monitoring its own state and responding autonomously to user presence indicators.

Inventive Principle:

Principle #25Self-service

3Reliability

If connector pins require complex assembly procedures, then electrical connections are more reliable, but manufacturing complexity increases

Engineering Contradiction:

Improveelectrical connectionVSAvoidassembly process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The connector pin uses spring-loaded heads that automatically establish reliable electrical connections through elastic deformation when mated with the socket. This mechanical spring mechanism replaces complex multi-step assembly procedures, providing both reliability and ease of manufacture through a single snap-fit operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
