Solution Overview

Problem

Traditional power plugs are often single-specification and inconvenient for use in foreign countries, requiring users to carry multiple adapter plugs, which are easily lost and cumbersome.

Innovation Solution

A charger and adapter plug assembly with multiple detachable plugs (AU, UK, EU standards) that can be stacked and stored, allowing for adaptation between US, JP, CN, TW, AU, UK, and EU electric standards, enabling easy travel and reducing the risk of loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a power plug is designed with a single specification, then the device complexity is reduced, but the adaptability to different country standards deteriorates

Engineering Contradiction:

Improveplug structureVSAvoidcompatibility with different receptacle standards

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The adapter plug body is designed to accommodate multiple types of adapter plugs (AU, UK, EU standards) through detachable connections, allowing a single base structure to serve multiple country-specific plug standards, thereby achieving multi-functionality without increasing overall device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple adapter plugs are purchased for different countries, then the adaptability to different standards is improved, but the ease of operation deteriorates due to carrying multiple individual plugs

Engineering Contradiction:

Improvecompatibility with different receptacle standardsVSAvoidconvenience of carrying and using multiple plugs

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Multiple adapter plugs of different specifications (AU, UK, EU) are merged into a single integrated assembly through detachable connections to the adapter plug body, allowing users to carry one consolidated unit instead of multiple separate plugs, thereby improving ease of operation while maintaining adaptability

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If multiple individual adapter plugs are carried, then the adaptability to different standards is improved, but the reliability deteriorates as they are easily lost

Engineering Contradiction:

Improvecompatibility with different receptacle standardsVSAvoidrisk of losing individual adapter plugs

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Multiple adapter plugs are combined into a single assembled unit with detachable connections, reducing the risk of loss by consolidating multiple components into one manageable assembly that is less likely to be misplaced or lost individually

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The invention provides a charger and adapter plug assembly including a first adapter plug, a second adapter plug, a third adapter plug and a charger. The first adapter plug has a set of AU standard pins and a first storage cavity with a first socket therein. The charger has two flat straight pins on one end and a USB port on the other end. The charger is detachably stored into the first storage cavity, so as to make the two flat straight pins electrically plugged into the first socket. The second adapter plug has a set of UK standard pins, a second storage cavity with an EU socket therein and an AU socket. The first adapter plug is detachably assembled to the second adapter plug, so as to make the AU standard pins electrically plugged into the AU socket. The third adapter plug has a set of EU pins and a second socket. The third adapter plug is detachably stored into the second storage cavity, so as to make the EU standard pins electrically plugged into the EU socket.
