Solution Overview
Problem
There is a need for a convenient and organized power solution for USB devices in utility bags and other containers that carry portable cordless power tools, as existing solutions do not efficiently utilize the battery packs of these tools as a power source for USB devices.
Innovation Solution
A system comprising a battery pack receptacle integrated into a utility bag that removably receives a cordless device battery pack and transfers power to a USB receptacle, allowing the battery pack to serve as a power source for USB devices, with integrated wiring and a universal design to accommodate various battery pack sizes and voltages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery pack receptacle is integrated into a utility bag to enable power transfer to USB devices, then power supply convenience for USB devices is improved, but device complexity increases
Solution Approach 1:
The patent combines the battery pack receptacle and USB power delivery system into an integrated unit that is incorporated into the utility bag. This merging of functions allows the bag to serve both as a carrying container and as a power distribution system, eliminating the need for separate charging equipment and thereby improving power supply convenience while managing device complexity through integration.
Solution Approach 2:
The battery pack receptacle is designed with universal compatibility to accept different battery pack types and voltages (e.g., 18V, 36V, 54V). This multi-functionality allows the same receptacle design to serve multiple voltage requirements and different USB devices simultaneously, improving ease of operation across various scenarios without proportionally increasing device complexity.
2Adaptability or versatility
If a universal battery pack receptacle design is used to accommodate various battery pack sizes and voltages, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The receptacle employs a universal design that can accommodate multiple battery pack types, sizes, and voltages (18V, 36V, 54V) through a single interface. This universality is achieved by designing contact points and structural features that work across different battery configurations, thereby improving adaptability while managing manufacturing precision through standardized design elements.
Solution Approach 2:
The system accommodates different battery voltages (18V, 36V, 54V) by incorporating voltage detection and regulation circuitry that automatically adjusts to the connected battery's parameters. This allows the receptacle to maintain manufacturing precision for a single design while adapting to various voltage inputs through electronic parameter adjustment rather than requiring multiple precision-designed receptacles.
3Loss of energy
If integrated wiring is implemented to connect the battery pack receptacle to the USB receptacle, then power transfer efficiency is improved, but ease of manufacture decreases
Solution Approach 1:
The integrated wiring system combines the power transfer pathway from the battery pack receptacle to the USB receptacle within a single integrated assembly. This merging reduces the number of separate connections and interfaces required, thereby improving power transfer efficiency by minimizing connection losses while simplifying the overall manufacturing process through reduced assembly steps.
