Cylindrical Battery Holder With Flexible Protrusions for Diameter Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders for conveyance of cylindrical batteries face issues with maintaining stability and durability due to damage from variations in outer can diameters during mass production, particularly when using elastic inner wall portions that are fixed at both ends, leading to reduced holding force over time.
Innovation Solution
A holder with tubular portions and protrusions having elasticity and flexibility, which warp to accommodate variations in outer can diameters, ensuring stable holding through elastic restoration forces and preventing damage during insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic inner wall portion is fixed at both ends to the outer wall tubular body, then the holder can provide initial holding force for the outer can, but the holding force deteriorates over time due to accumulated damages from insertion and removal of outer cans with varying diameters
Solution Approach 1:
The holder is divided into two functional parts: a rigid outer wall tubular body that provides structural support and positioning, and a removable resilient battery holding portion that provides adaptive holding force. This segmentation allows the resilient portion to be replaced when worn, maintaining reliable holding force throughout the holder's service life.
Solution Approach 2:
The resilient battery holding portion is designed as a replaceable component that can be recovered and reused. When the resilient portion shows signs of wear or damage, it can be removed and replaced with a fresh one, extending the overall service life of the holder while maintaining reliable holding force.
2Adaptability or versatility
If the elastic inner wall portion is disposed with clearance between the outer wall tubular body and inner wall portion, then the holder can accommodate variations in outer can diameters, but it becomes difficult to ensure sufficient displacement of the inner wall portion in the outer-diameter direction
Solution Approach 1:
The battery holding portion is designed to be movable relative to the outer wall tubular body, allowing dynamic adjustment to accommodate variations in outer can diameters. The resilient nature of this portion enables it to deflect and adapt to different can sizes while maintaining adequate holding force through its elastic properties.
3Reliability
If the battery holding portion is formed to swell inward from the elastic inner wall portion, then the holder can stably hold the cylindrical battery, but the holding portion may be damaged due to scraping by outer cans with large diameters during mass production
Solution Approach 1:
The resilient battery holding portion acts as a cushioning element that can deform and absorb impact or scraping forces from outer cans with large diameters. This beforehand cushioning protects the structural integrity of the holder while maintaining stable holding of the battery during mass production.
Solution Approach 2:
The battery holding portion is formed as a flexible resilient structure that can deform to accommodate variations in outer can dimensions. This flexibility allows it to adapt to different can sizes without suffering damage from scraping or excessive force during insertion and removal operations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The holder effectively absorbs variations in outer can diameters, maintaining holding force over a long period and preventing damage, while also improving alignment accuracy and enabling reliable assembly processes.
Implementation Method 1
the protrusion has elasticity and flexibility, and the protrusion is disposed on an inner diameter side of an outer circumferential surface of the cylindrical body at an expected housing position such that a side surface of the distal end of the protrusion is allowed to come into contact with the outer circumferential surface while the protrusion is warped to an outer diameter side of the hollow portion

AI summary
A holder for conveyance of a cylindrical body includes a tubular portion having a hollow portion in which a cylindrical body is housed, and a protrusion having a base end connected to an inner wall surface of the tubular portion and a distal end formed as a free end. The protrusion has elasticity and flexibility, and the protrusion is disposed on an inner diameter side of an outer circumferential surface of the cylindrical body at an expected housing position such that a side surface of the distal end of the protrusion is allowed to come into contact with the outer circumferential surface while the protrusion is warped to an outer diameter side of the hollow portion.
