Capsule holder for holding a gas capsule
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas capsule holders are prone to injury and damage due to high pressures, especially when using incorrect capsules, leading to high weight and cost due to robust, single-piece construction.
Innovation Solution
A capsule holder design with a separate threaded ring and sleeve-like cover that allows for thinner wall thicknesses, featuring material-locking and form-locking connections, anti-rotation features, and a soft cover for improved handling and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capsule holders are constructed as robust, single-piece cast parts to prevent damage from high pressures, then reliability and safety are improved, but weight and manufacturing cost increase
Solution Approach 1:
The capsule holder is divided into multiple components: a holder body and a separate sleeve-like cover. The cover can be removed to allow capsule insertion and replacement, while the holder body remains fixed. This segmentation allows the structure to be optimized for strength where needed while reducing material usage overall, thereby lowering weight without compromising pressure resistance.
Solution Approach 2:
The capsule holder combines different materials with complementary properties: the holder body is made from pressure-resistant material (such as metal or hard plastic) to withstand high pressures, while the removable cover is made from softer, lighter material that provides user comfort and ease of handling. This composite approach achieves both safety and weight reduction.
2Reliability
If capsule holders are constructed as robust, single-piece cast parts to prevent damage from high pressures, then reliability and safety are improved, but manufacturing cost increases
Solution Approach 1:
By dividing the capsule holder into a permanent holder body and a removable cover, each component can be manufactured separately using optimized processes. The holder body can be produced with precise pressure-resistant features, while the cover can be made from lighter, cheaper materials. This reduces overall manufacturing cost compared to producing a single-piece cast structure with the same safety requirements.
Solution Approach 2:
The design applies different material qualities and structural characteristics to different parts of the capsule holder. The holder body receives full structural reinforcement for pressure resistance, while the cover uses lighter materials sufficient only for user interaction and protection during normal operation. This localized optimization reduces material costs while maintaining safety.
3Ease of operation
If a sleeve-like cover completely encloses the gas capsule receiving element, then user safety and grip are improved, but material usage and weight increase
Solution Approach 1:
The sleeve-like cover is designed as a thin-walled structure made from flexible or semi-flexible material that provides sufficient protection and user grip without requiring thick walls. The cover's flexibility allows it to conform to the capsule shape while maintaining structural integrity during normal handling, achieving good user interaction with minimal material usage and weight.
