Breathable Core Air Pressure Balancing Plug for Ink Pens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional writing pens with ink storage have complex structures and high manufacturing costs due to the need for multiple parts to maintain air pressure balance and prevent ink leakage during writing.
Innovation Solution
A writing pen with a simple structure utilizing breathable cores with nanopores, integrated into an air pressure balancing plug, allows ambient air into the ink storage compartment while preventing ink leakage, using a design that includes a transfer core and relay core connected to the writing nib and a pen body with a pen cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple parts (dust-proof plate, labyrinth breathable plug, nano-permeable plate, one-way valve) are used to achieve air communication and prevent ink leakage, then air pressure balance is maintained, but device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent combines multiple separate components (dust-proof plate, breathable plug, nano-permeable plate, and one-way valve) into a single integrated breathable core. This core contains porous particles that simultaneously provide dust protection, breathability, and one-way valve functionality, thereby maintaining air pressure balance while significantly reducing device complexity and the number of assembly steps
Solution Approach 2:
The breathable core is constructed using composite materials - specifically, porous particles (such as porous polymer beads or ceramic particles) with controlled pore sizes. These particles create a material that inherently combines multiple functions: filtering dust, allowing air permeation, and preventing ink leakage through their porous structure, eliminating the need for separate mechanical components
2Reliability
If multiple parts and assembly procedures are used to prevent ink leakage while allowing air communication, then writing reliability is improved, but manufacturing cost increases
Solution Approach 1:
By merging multiple functional components into a single breathable core, the patent reduces the number of parts that need to be manufactured and assembled. This integration simplifies the manufacturing process, reduces inventory requirements, and lowers assembly labor costs while maintaining the same level of writing reliability
Solution Approach 2:
The breathable core can be designed as a disposable or replaceable component that is inexpensive to manufacture. By using simple porous particles that can be easily produced through standard manufacturing processes, the patent enables cost-effective replacement if the core becomes contaminated or degraded, reducing overall system cost
