Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of power source devices with multiple batteries connected in series is cumbersome due to the need for numerous connecting members, which increases the workload and makes it difficult to achieve a compact, lightweight design, especially when the number of batteries is increased to raise the voltage.
Innovation Solution
A power source device design that includes a battery assembly with positioning and displacement sections to facilitate the alignment and connection of connecting members with the corresponding electrodes, using positioning projections and holes, guide projections and holes, and elastically deformable coupling parts to simplify the assembly process.

Engineering Contradiction Analysis
1Power
If multiple connecting members are used to connect batteries in series, then the voltage of the power source device is increased, but the assembly work becomes more cumbersome and time-consuming
Solution Approach 1:
The patent combines multiple connecting members (bus bars) onto a single plate structure, creating an integrated assembly unit. This merging approach allows multiple battery connections to be established simultaneously when the plate is installed, rather than requiring separate installation steps for each connecting member, thus resolving the contradiction between achieving high voltage through multiple connections and maintaining efficient assembly speed.
2Ease of manufacture
If multiple connecting members are attached to a plate before mounting, then the assembly process is simplified, but the electrodes must slide through multiple holes causing friction and making assembly difficult
Solution Approach 1:
The connecting members (bus bars) are pre-attached to the plate in predetermined positions before the plate is mounted on the battery assembly. This preliminary action allows the electrodes to be routed through the plate holes and bus bar holes simultaneously, establishing multiple connections in one operation. The friction issue is mitigated by the preliminary positioning that guides the electrodes through the holes during the single assembly motion.
3Power
If the number of batteries is increased to raise voltage, then the power output is improved, but the device becomes more complex and harder to design compactly
Solution Approach 1:
Multiple connecting members are merged onto a single plate structure, reducing the number of separate components that need to be managed. This integration simplifies the overall device structure despite the increased number of batteries, allowing for a more compact and manageable design while maintaining the higher voltage output achieved through the series connection of multiple batteries.

AI summary
A power source device includes a battery assembly which includes a plurality of batteries each having a positive electrode at one end and a negative electrode at the other end, a plurality of connecting members, each of which connects the positive electrode of one battery and the negative electrode of the other battery of the battery assembly, the one and the other batteries adjoining each other, and a plate to which the connecting members are attached, and the plate adapted to the battery assembly. The battery assembly and the plate include a positioning section that relatively positions the battery assembly and the plate. The battery assembly and the plate include a plate displacement section that displaces the plate so that the connecting members relatively abut against the corresponding positive electrodes and negative electrodes of the battery assembly when the plate is mounted on the battery assembly.
