Gas Container Sealing and Guiding Element for Piercing Lance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas container systems face challenges in ensuring a gas-tight connection with a piercing unit, leading to complex handling, potential leakage, and increased material costs due to the need for precise alignment and frequent replacement of seals, which complicates the use and disposal of gas containers.
Innovation Solution
A gas container system with a sealing and guiding element integrated into the base body head, featuring a cavity for the piercing lance and a spring-assisted piercing unit that ensures easy opening and automatic removal, eliminating the need for external caps and reducing the risk of leakage by providing force support during the piercing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal is arranged in a groove-shaped recess on the end face of the gas capsule and a cap is placed on it, then a gas-tight connection can be achieved, but the handling becomes complex and time-consuming due to the need for precise alignment and the risk of seal damage or jamming
Solution Approach 1:
The seal is extracted from the cap and placed directly in the cavity of the sealing and guiding element on the gas container. This eliminates the need for a separate cap and groove-shaped recess, allowing the seal to be accessed and replaced independently without complex alignment requirements.
Solution Approach 2:
The sealing system is segmented into distinct components: the seal is separated from the cap structure and integrated into the sealing and guiding element. This allows the seal to be independently replaced without removing or repositioning the entire cap assembly, simplifying maintenance and handling.
2Reliability
If a seal is directly arranged on the piercing lance to seal the cavity, then the sealing function is achieved, but the seal must be frequently renewed or replaced by the user due to wear, increasing complexity and potential for error
Solution Approach 1:
The seal acts as an intermediary component positioned in the cavity of the sealing and guiding element, mediating between the piercing lance and the cavity. This location allows the seal to be easily accessed and replaced without removing the piercing lance or disassembling complex structures, reducing maintenance complexity.
3Reliability
If a cap with a groove-shaped recess and seal is used on the gas capsule, then gas-tight sealing is achieved, but additional material costs arise and the structure becomes more complex
Solution Approach 1:
The sealing and guiding element merges multiple functions into a single component: it provides the cavity for the piercing lance, incorporates the seal directly in its structure, and guides the piercing lance during insertion. This integration eliminates the need for separate cap, groove-shaped recess, and seal components, reducing structural complexity and material costs.
Solution Approach 2:
The sealing and guiding element serves multiple purposes: it seals the cavity, guides the piercing lance during insertion, and provides structural support. This multi-functional design replaces the traditional cap structure, reducing the number of components and overall system complexity.
4Ease of operation
If the piercing lance is manually inserted and held in place without assistance, then the piercing operation can be performed, but the risk of the lance getting stuck or jammed increases, requiring careful and slow handling
Solution Approach 1:
The spring element provides automatic assistance during the piercing operation. After the piercing lance penetrates the sealing and guiding element, the spring element automatically pushes the lance further into the cavity, ensuring complete sealing without requiring manual force or complex positioning by the user.
