Pivoted USB Connector Module for Portable Lamp Power Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electric lamps with USB connectors require an external connecting cable for charging and parameter setting, making them inconvenient and prone to moisture exposure when used independently.
Innovation Solution
A portable electric lamp design featuring a USB connector module with removable fixing means that integrates into a pivoting housing on the back support body, providing a secure, moisture-proof connection without an external cable, allowing direct connection to external sources like computer ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a USB connector is provided on the power supply unit for external connection, then charging and parameter setting functions are enabled, but the connector is exposed to moisture and external damage when used independently
Solution Approach 1:
The power supply unit is divided into two segments: a first module containing the USB connector and a second module containing the accumulator. This segmentation allows the connector to be isolated in a protective housing when not in use, preventing moisture exposure while maintaining charging functionality.
Solution Approach 2:
The USB connector is nested within a protective housing formed by the first module. When the first module is connected to the back support body, the connector is housed and protected. When disconnected, the connector remains within the first module's protective structure, shielding it from environmental harm.
2Object-affected harmful factors
If an external connecting cable is required for USB connection, then the connector can be protected, but the device becomes inconvenient to use and requires permanent carrying of the cable
Solution Approach 1:
The USB connector is extracted from the conventional cable-based connection system and integrated directly into the power supply unit. This extraction eliminates the need for external cables while maintaining connector protection through the integrated housing design.
Solution Approach 2:
The first module serves dual functions: it protects the USB connector when disconnected and provides the connection interface when attached to the back support body. This self-service design eliminates the need for separate protective cases or external cables.
3Ease of operation
If the USB connector is exposed for direct connection, then connection convenience is improved, but the connector's integrity is compromised under various external conditions
Solution Approach 1:
The protective housing provides localized protection precisely where the USB connector is located. The housing structure is designed to shield the connector from moisture and physical damage while allowing easy access when the first module is attached to the back support body.
Solution Approach 2:
The connection system is dynamic: the first module can be attached to or disconnected from the back support body. When attached, the connector is protected within the housing; when disconnected, the connector remains accessible within the first module's protective structure, adapting to different usage scenarios.

AI summary
A power supply unit including an accumulator, a back support body with means configured for holding the back support body on a user's head and connect to a lighting device, at least one first module provided with a USB connector, and means for removably securing the at least one first module to the back support body. The back support body also includes a hollow element for receiving the connector, such hollow element being mounted so as to pivot around a transverse axis of the back support body.
