Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing output devices for multi-component liquids, particularly chemiluminescent markers, suffer from insufficient mixing and improper venting or pressure balancing, leading to incomplete mixing and premature failure due to cross-contamination and sensitivity to impurities.
Innovation Solution
A vented output device with a barrel, nib, and binary ink storage assembly featuring glass ampoules arranged in pairs, along with vent channels and a spacing ring to ensure uniform mixing and pressure balance, using materials like polyethylene and acrylic fiber for the barrel and nib, and ABS plastic for the spacing ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If porous adsorbent materials are used for liquid output, then the liquid can be delivered to the writing tip, but the chemiluminescent liquid is highly sensitive to impurities and cross-contamination occurs
Solution Approach 1:
The device divides the liquid storage into separate compartments for different liquid components, preventing cross-contamination. Each compartment can be independently sealed and accessed, allowing the liquids to remain separate until needed while delivering them uniformly to the writing tip.
Solution Approach 2:
A valve mechanism acts as an intermediary control element between the liquid storage compartments and the writing tip. The valve precisely controls liquid flow, preventing premature mixing and contamination while ensuring reliable delivery of the chemiluminescent liquid mixture.
2Ease of operation
If a valve or ball release structure is used to control liquid flow, then liquid can be delivered controllably, but cross-contamination occurs when the valve closes and opens
Solution Approach 1:
The device employs a disposable seal or membrane that is discarded after single use, eliminating the risk of cross-contamination from reusable valve mechanisms. This disposable element ensures clean liquid delivery without the contamination risks associated with repeated opening and closing of valve structures.
3Device complexity
If no air intake and exhaust structure is provided, then the structure is simple, but the external atmosphere cannot enter the pen and ink discharge function fails
Solution Approach 1:
The device incorporates localized air intake and exhaust openings at specific positions within the barrel structure. These localized openings allow atmospheric air to enter and exit at appropriate locations without complicating the overall device architecture, enabling proper ink discharge while maintaining structural simplicity.
4Reliability
If luminescent liquid is stored in a movable cavity with separation structure, then mixing can be achieved, but the structure is complicated to operate and expensive
Solution Approach 1:
The device merges the liquid storage and mixing functions into a single integrated barrel structure. The separation of liquid components is achieved through internal partitioning within the barrel, eliminating the need for separate movable cavities and complex separation mechanisms, thereby reducing operational complexity and manufacturing costs.
5Reliability
If premixing cavity with sphere and orifice plate is used, then liquid can be mixed, but the structure is complex involving high costs and uncertain effect
Solution Approach 1:
The device extracts the mixing function from complex premixing cavities with spheres and orifice plates, achieving liquid mixing through simpler internal barrel partitioning and flow control mechanisms. This extraction of the mixing function into a more straightforward structure reduces complexity and cost while maintaining reliable mixing performance.

AI summary
A vented output device for uniformly mixed liquid comprising a barrel defining a reservoir for containing the uniformly mixed liquid, and at least one vent channel extending from a first vent opening in fluid flow communication with an exterior of the device and second vent opening in fluid flow communication with the reservoir. A binary ink storage assembly includes multiple glass ampoules arranged in pairs, which are placed inside the barrel in parallel. The invention provides a reliable, simple and low-cost output device for solving the problem of not allowing the liquid to be uniformly mixed and output when a chemiluminescent marker or pen is activated.
