Battery Spacer With Segmented Retaining Ribs For Size Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery spacers lack adequate retention ability, leading to batteries accidentally popping out due to size variations among different manufacturers or types, and fail to properly fit batteries with outside diameters outside the preset range.
Innovation Solution
A battery spacer design featuring a cylindrical body with anode-side and cathode-side catching pieces having engagement hooks that engage with the battery's outer surface, providing a secure hold regardless of the battery's diameter, and an anode exposure hole for partial negative terminal exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional battery spacers use fixed-size retaining structures, then they can retain batteries of a specific size, but they fail to accommodate batteries with different outside diameters from different manufacturers
Solution Approach 1:
The retaining ribs are designed with varying heights (first, second, and third retaining ribs with different heights) to accommodate batteries of different outside diameters. Each retaining rib creates a retaining space adapted to specific battery sizes, allowing the same spacer structure to reliably retain batteries with different dimensions.
2Reliability
If battery spacers are designed for a specific battery size, then they provide stable retention, but they cannot be used with batteries of other sizes
Solution Approach 1:
The retaining structure is segmented into multiple retaining ribs (first, second, third retaining ribs) with different heights, creating distinct retaining spaces. This segmentation allows the spacer to provide stable retention for different battery sizes simultaneously, as each segmented retaining space is optimized for specific battery dimensions.
3Ease of manufacture
If battery retaining structures use uniform design, then they are simple to manufacture, but they cannot accommodate size variations in batteries from different manufacturers
Solution Approach 1:
The retaining ribs are designed with varying heights (first, second, and third retaining ribs with different heights) to accommodate batteries of different outside diameters. Each retaining rib creates a retaining space adapted to specific battery sizes, allowing the same spacer structure to reliably retain batteries with different dimensions.
4Adaptability or versatility
If battery spacers use multiple retaining structures for different battery sizes, then they improve versatility, but they increase structural complexity
Solution Approach 1:
Multiple retaining ribs (first, second, third retaining ribs) with different heights are merged into a single integrated spacer body. This combining of multiple retaining functions into one unified structure achieves versatility for different battery sizes while maintaining manufacturing simplicity and avoiding excessive structural complexity.

AI summary
A battery spacer 2 comprises: a cylindrical case body 4 into which a battery 3 is inserted; a bottom wall portion 8 with which an anode-side end of the battery 3 is to come into contact, the bottom wall portion 8 having an anode exposure hole 12 from which a negative terminal 13 of the battery 3 is partially exposed; an annular top wall member 6 that is located opposite to the bottom wall portion 8 and has a central opening 54 into which the battery 3 is inserted; a plurality of anode-side catching pieces 34 and 36 that have anode-side engagement hooks 40 and 42 extending from the circumference of the anode exposure hole 12 toward the interior of the case body 4 and engaging with an anode-side outer peripheral surface of the battery 3, and hold the anode side of the battery 3; and a plurality of cathode-side catching pieces 58, 60, and 62 that have cathode-side engagement hooks 64, 66, and 68 extending from the circumference of a central opening 54 toward the interior of the case body 4 and engaging with a cathode-side outer peripheral surface of the battery 3, and hold the cathode side of the battery 3.
