Ink Jet Perfume Delivery System with Capillary Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively deliver perfume mixtures into the air using ink jet technology, as they are primarily designed for printing on substrates rather than air diffusion.
Innovation Solution
A delivery system comprising an ink jet head, a reservoir, and a power source, utilizing 'drop-on-demand' or 'continuous' ink jet printing processes to atomize a perfume mixture into the air, with a membrane of nozzles and a capillary element to ensure efficient and stable delivery of a fluid composition with high perfume content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ink jet technology is used to deliver perfume mixtures, then atomization efficiency is improved, but the system is designed for printing on substrates rather than air diffusion
Solution Approach 1:
The patent modifies the fluid composition parameters by formulating a perfume mixture with high perfume content (greater than 50% by weight) and specific viscosity characteristics (less than 20 centipoise) to make it suitable for ink jet atomization into air, rather than for substrate printing
Solution Approach 2:
The patent introduces a capillary element as an intermediary component between the reservoir and ink jet head to ensure stable fluid delivery and prevent clogging, enabling the ink jet system to effectively deliver perfume mixtures into air
2Quantity of substance
If high perfume content fluid composition is used, then fragrance character is improved, but viscosity control becomes critical to prevent clogging
Solution Approach 1:
The patent carefully controls the viscosity parameter of the fluid composition to be less than 20 centipoise while maintaining high perfume content greater than 50% by weight, optimizing both fragrance character and flow characteristics to prevent clogging
Solution Approach 2:
The patent incorporates a capillary element beforehand to cushion and stabilize fluid delivery, preventing clogging issues before they occur by ensuring smooth, controlled flow to the ink jet nozzles
3Productivity
If ink jet head is used for air diffusion, then delivery effectiveness is improved, but system stability must be optimized to maintain consistent atomization
Solution Approach 1:
The capillary element acts as an intermediary that stabilizes fluid delivery to the ink jet head, ensuring consistent atomization by maintaining steady fluid flow and pressure, thereby improving atomization consistency
Solution Approach 2:
The patent ensures continuous and stable fluid composition delivery through the capillary element and ink jet system, maintaining consistent atomization action without interruption or variation, which is critical for reliable perfume delivery into air
