Integrated Power Adaptor and Speaker with Mains Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often need to carry separate devices for powering and charging portable audio equipment and headphones, as well as a mains adaptor, which is inconvenient and requires additional space.
Innovation Solution
A device combining a power adaptor with integrated AC/DC rectification and speaker devices, where the speaker devices have electrical power pins that can connect to a mains socket for power and switch between audio signal reception and power transmission, allowing for a single compact unit that can both charge/power devices and play audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users carry separate devices for power adaptor and speaker devices, then each device can perform its dedicated function reliably, but users need to carry multiple components which increases portability burden and space requirements
Solution Approach 1:
The patent combines a power adaptor and speaker devices into a single integrated unit. The power adaptor includes a housing with a power outlet, while speaker devices (headphones or earphones) are coupled to the housing and can be electrically connected to the power outlet. This merging allows users to carry one device instead of multiple separate components, reducing portability burden while maintaining both power adaptation and audio playback functions.
2Adaptability or versatility
If speaker devices have electrical power pins that connect to mains socket, then the device can function as a power adaptor, but the device structure becomes more complex with switching mechanisms
Solution Approach 1:
The speaker devices incorporate movable electrical power pins that can be positioned in different configurations. When the pins are in a first configuration, they connect to the mains socket to enable power adaptor functionality. When positioned in a second configuration, they connect to the power outlet to enable audio signal reception. This dynamic repositioning allows a single device to adapt between two distinct functions without requiring complex switching mechanisms, as the physical movement of the pins themselves performs the switching function.

Function Achieved in This Case
Enables users to carry a single device that can both power/charge other devices and play audio, reducing the need for multiple components and allowing for a more compact design, while maintaining functionality for both power and audio use.
Implementation Method 1
the power adaptor comprises an AC/DC rectifier for receiving an input AC mains power supply corresponding to the input electrical power and outputting a DC current

AI summary
A device (1) has a power adaptor (10) and speaker devices (50). The power adaptor (10) is for receiving input electrical power and outputting electric power for charging a rechargeable battery or powering another device. The speaker devices (50) are for outputting audio. Each speaker device (50) has an electrical power pin (52) for connection to a respective socket of a mains power socket. Each speaker device (50) has an electrical connection (54) to the power adaptor (10) so that the electrical power pins (52) of the speaker devices (50) can receive input electrical power from a mains socket to which the electrical power pins (52) are connected in use and pass the input electrical power to the power adaptor (10) via the electrical connections (54).
