Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB charger products with built-in outlets are heavy and impractical for desk installation due to the weight of power cords, requiring users to bend and potentially causing injuries, and lack efficient USB charging capabilities with high power output.
Innovation Solution
A hand-reachable desktop USB charger with a built-in wire arrangement that includes a liquid display unit, LED lights, and multiple USB ports, capable of converting 120 VAC to 5 VDC directly, providing a stable and convenient power source with a built-in wire management system to prevent cord weight issues and enhance usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional USB charger products with built-in outlets are used, then power supply function is provided, but the weight of power cords makes the product heavy and impractical for desk installation
Solution Approach 1:
The power cord is separated from the main charger body and integrated into a separate wire arrangement system with roller, retractable means, spring means, or twist means. This segmentation allows the charger body to remain lightweight for desk installation while the power cord functionality is provided by the separate wire management system.
Solution Approach 2:
The wire arrangement system utilizes vertical space and three-dimensional positioning to manage the power cord, allowing it to be stored, coiled, or retracted in a compact manner that does not add significant weight to the desk surface footprint while providing full power cord functionality.
2Ease of operation
If conventional USB charger products are used, then charging capability is provided, but users must bend which may cause injuries
Solution Approach 1:
The charger is designed as a desktop unit with multiple USB ports and AC outlets that can charge multiple devices simultaneously at desk level. This multi-functional design eliminates the need for users to bend down to floor-level chargers or power strips, providing accessible charging while preventing waist and knee injuries.
3Ease of operation
If AC power wires are extended for desk installation, then power supply reach is improved, but messes are caused by AC wires
Solution Approach 1:
The power cord management system combines multiple functions including roller mechanisms, retractable means, spring means, or twist means into an integrated wire arrangement system. This merging of functions allows the power cord to be neatly stored, coiled, or retracted, eliminating messy wire arrangements while maintaining adequate reach for desk installation.
4Productivity
If laptop USB ports or portable USB chargers are used, then portability is maintained, but power output is insufficient for efficient charging
Solution Approach 1:
The desktop charger is designed to provide high power output capabilities with multiple USB ports and AC outlets that can deliver sufficient power for fast charging of multiple devices simultaneously. The unit serves itself by incorporating built-in power conversion circuitry that efficiently converts AC power to USB power, eliminating the need for external power adapters and providing superior charging speed compared to portable chargers.

AI summary
USB Charger related products have a built-in liquid display unit including decorative, reflective, and/or miniature items within a medium and an optional heater-means to cause movement of medium and the items included within the medium. The charger related products are supplied with power from an AC power wire, the 110 VAC to 250 VAC input power being converted into an output charging current having a range of 1.0 A to 12 A and 3.5 VDC to 8.5 VDC. In addition, USB digital signal or data ports may be connected with an external computer, consumer electric device, or communication device, and the USB charger related products may further include additional devices such as an AC outlets(s), sensor, motion sensor, remote control, timer, LEDs, power fail circuitry, audio, video, or smell devices, or other electric or electronic devices to provide one or more additional functions in addition to the charging function.
