Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chargeable single-part batteries are inconvenient to use as they require individual removal from devices for charging, and their chargers are bulky and costly to manufacture.
Innovation Solution
A composite battery device comprising two single-part batteries connected in series, housed in a casing with exposed positive and negative poles, and a protective circuit board, allowing for charging without removing the device from a flashlight, using a socket and electrodes for coaxial connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional chargeable single-part batteries are used, then the batteries can be directly put in electric appliances, but they require individual removal for charging which is inconvenient
Solution Approach 1:
The patent combines multiple single-part batteries into a unified battery set housed within a single casing structure. The casing integrates holding portions for multiple batteries, a socket for charging connection, and a protective circuit board, transforming separate charging operations into a single integrated charging unit that can be charged as one device.
2Ease of manufacture
If chargers are designed with hollow holding portions to contain batteries, then batteries can be charged, but the chargers become bulky and costly to manufacture
Solution Approach 1:
The patent extracts the charging functionality from a separate bulky charger device and integrates it directly into the battery set. The socket is built into the battery set casing, allowing charging connections to be made directly to the batteries without requiring a separate charger with hollow holding portions, thereby eliminating the need for large charger dimensions.
3Ease of operation
If multiple batteries are held in a plastic box to form a battery set, then they can be charged together, but the plastic box increases manufacturing cost and complexity
Solution Approach 1:
The casing structure serves multiple functions simultaneously: it acts as the housing for the battery set, provides holding portions for securing multiple batteries, contains the socket for charging connection, and houses the protective circuit board. This multi-functional integration eliminates the need for separate plastic boxes or additional structural components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient charging of the battery set within a device, reducing manufacturing costs and improving user experience by integrating charging functionality directly into the battery device.
Implementation Method 1
the left and the right covering parts of the casing can be glued together or welded together by means of ultrasonic welding

AI summary
A battery device includes a battery set, and a casing; the casing includes a right covering part and a left covering part, which are joined together to provide a holding room for the battery set; the battery set include at least two batteries, and are held in the casing with positive and negative poles thereof being exposed through front and tail ends of the casing respectively; a socket is held in the casing, and electrically connected with the positive and the negative poles of the battery set; thus, after a plug of a charger is inserted in the socket, the single-part batteries together will be charged through the charger without the battery device being located on the charger.
