Integrated Power Strip Carrying Case for Multi-Brand Battery Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of multiple battery chargers for different brands of portable electric power tools is cumbersome due to the lack of a universal battery/charger system, requiring multiple chargers and outlets, which complicates transportation and on-site charging.
Innovation Solution
An electrical power strip is integrated into a carrying case with multiple mounted chargers, allowing all spare batteries to be charged simultaneously when plugged into a power source, enabling easy swapping of charged batteries for use while the depleted ones are recharged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple chargers of different types are used to charge batteries for different brands of power tools, then all battery types can be charged, but the device complexity and transportation difficulty increase
Solution Approach 1:
The patent combines multiple separate chargers of different types into a single integrated carrying case. All chargers are mounted inside the case and connected to a common power strip, merging what would otherwise be separate devices into one unified portable charging station.
Solution Approach 2:
The carrying case serves multiple functions: it stores multiple different types of chargers, holds corresponding batteries, provides a common power distribution system through the power strip, and offers a portable enclosure for all charging components. This multi-functional design eliminates the need to manage separate chargers and storage solutions.
2Adaptability or versatility
If multiple chargers are transported to the job site, then all battery types can be charged, but the transportation burden and setup complexity increase
Solution Approach 1:
The patent merges multiple chargers, batteries, and a power strip into a single portable carrying case with a handle. This integration allows the user to transport all charging components as one unified unit rather than carrying separate devices, significantly improving transportation convenience.
Solution Approach 2:
The chargers and batteries are nested within the carrying case, with components organized inside the enclosed space. The power strip is mounted inside the case, and chargers are positioned to fit within the case structure, creating a compact nested arrangement that optimizes portability.
3Productivity
If multiple electrical outlets are available at the job site, then all chargers can be plugged in simultaneously, but the requirement for multiple outlets increases setup difficulty when outlets are limited
Solution Approach 1:
The patent combines multiple charger power inputs into a single power strip that draws from one electrical outlet. This consolidation allows all chargers to be powered through a single outlet connection, eliminating the need for multiple outlets and simplifying the setup process at job sites with limited electrical access.
Solution Approach 2:
The power strip acts as an intermediary device between the single electrical outlet and multiple chargers. It distributes electrical power from one outlet to multiple chargers simultaneously, enabling multi-brand battery charging without requiring multiple outlets.
4Duration of action of moving object
If duplicate batteries are kept for each power tool, then continuous tool operation is maintained, but the quantity of batteries and chargers to manage increases
Solution Approach 1:
The patent merges the storage and charging of multiple duplicate batteries into a single organized system within the carrying case. All batteries and their corresponding chargers are consolidated in one location, reducing the management burden despite maintaining multiple battery copies for continuous operation.
Solution Approach 2:
The system pre-charges multiple batteries in advance using the integrated chargers. When a battery is depleted, a pre-charged duplicate is immediately available for swapping, eliminating downtime without requiring the user to manually manage individual charging cycles of separate batteries.
