Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid nitrogen injectors used in large factories are too large and costly for small businesses, making it difficult for them to efficiently seal beverage cans without causing shape deformation due to air shrinkage over time.
Innovation Solution
A mini liquid nitrogen injector with a reduced configuration, featuring a liquid nitrogen supply pipe, discharge pipe, photo sensor, timer, and a nozzle system that maintains pressure and temperature, allowing precise control over nitrogen injection to prevent can distortion and microbial growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional liquid nitrogen injectors are used in large factories, then mass production efficiency is improved, but device size and installation cost increase significantly
Solution Approach 1:
The conventional large-scale liquid nitrogen injector is segmented into a compact miniaturized version with separate functional modules (nozzle, tank, control system) that can be integrated in a space-efficient configuration, enabling small businesses to use liquid nitrogen injection without requiring factory-scale equipment
Solution Approach 2:
The essential liquid nitrogen injection function is extracted from the complex factory production line system and isolated into a standalone mini injector unit, allowing the core functionality to be used independently without requiring the entire factory infrastructure
2Shape
If liquid nitrogen is injected into beverage cans, then can shape stability is improved, but equipment complexity increases
Solution Approach 1:
The liquid nitrogen injection capability is extracted as a separate attachable module that can be added to existing can sealing equipment without requiring complete system replacement, thus improving can shape stability while minimizing the increase in overall equipment complexity
Solution Approach 2:
The mini liquid nitrogen injector is designed with self-contained controls and automatic operation features that require minimal user intervention, reducing the operational complexity despite adding functional capabilities for shape stabilization
3Duration of action of stationary object
If liquid nitrogen injection is implemented, then shelf life extension is improved, but initial investment cost increases
Solution Approach 1:
The mini liquid nitrogen injector uses disposable or easily replaceable components such as the injection nozzle and sealing elements, allowing small businesses to implement liquid nitrogen preservation without significant ongoing investment in maintenance and replacement of expensive durable components

AI summary
A mini liquid-nitrogen injector injects liquid nitrogen into an aluminum can when drinks and the like are packed at small shops and the like, so as to enable movement and distribution, and thus long-term storage is possible, and a predetermined amount of liquid nitrogen is injected into a can facilitating eating, so as to push out oxygen therein and allow nitrogen, which is an inert gas, to occupy the space, so that, during packing, in order to inhibit microbial propagation and prevent taste alteration, liquid nitrogen is injected into an aluminum can, thereby enabling movement and distribution.
