Solid Silica Flaky Drying Agent with Red Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medicinal silica gel drying agents have poor moisture absorption capacity, lead to secondary pollution due to crumb formation, and pose a risk of erroneous intake by senior citizens and children due to similar shape with medicines, requiring multiple production processes and increasing labor intensity.
Innovation Solution
A medicine bottle design incorporating a bubble cap-type solid silica flaky drying agent with tea filter paper, a bubble cap baseplate, and moisture absorption openings, fixed by a locking notch, ensuring the drying agent is securely retained and preventing direct contact with medicines, using a non-toxic silicon oxide-based drying agent with enhanced compressive strength and absorption capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If solid silica flaky drying agent is used with similar shape to medicine, then moisture absorption capacity is improved, but risk of erroneous intake by senior citizens and children increases
Solution Approach 1:
The patent applies color changes by coating the white solid silica flaky drying agent with red pigment, making it red in color. This color differentiation clearly distinguishes the drying agent from medicines, preventing erroneous intake by senior citizens and children while maintaining the high moisture absorption capacity of the silica-based material.
2Ease of manufacture
If traditional silica gel drying agent is used, then packaging process requires multiple steps with manual handling, but moisture absorption capacity is poor and saturation is reached quickly
Solution Approach 1:
The patent applies parameter changes by transforming the drying agent from traditional spherical silica gel to flaky solid silica structure, and further improving it by coating with red pigment. This structural and compositional parameter change enhances moisture absorption capacity while enabling direct placement into medicine bottles without complex packaging steps.
Solution Approach 2:
The patent merges the drying agent preparation and packaging into a single step by designing the solid silica flaky drying agent with red coating that can be directly placed into medicine bottles, eliminating the need for separate packaging bags or vials and manual handling steps.
3Productivity
If solid silica flaky drying agent is used without packaging, then production process is simplified, but dust and microbial contamination risk increases
Solution Approach 1:
The red coating on the solid silica flaky drying agent serves dual purposes: it prevents dust formation by binding the silica particles together, and the colored coating acts as a visual indicator that reduces microbial contamination risk by making the drying agent easily distinguishable and less likely to be mishandled.
Solution Approach 2:
The patent uses composite materials by combining solid silica flake base material with red pigment coating. This composite structure maintains the high moisture absorption capacity of silica while the coating layer prevents dust generation and reduces microbial contamination, enabling direct placement without additional packaging.

AI summary
A medicine bottle with a solid silica flaky drying agent is disclosed. The solid silica flaky drying agent is wrapped in a filter paper and packed inside a bubble cap on which a number of holes are provided for moisture absorption. The bubble cap containing the solid silica flake drying agent can be attached to the cap of the medicine bottle via a baseplate behind a circular locking notch for preventing the solid silica flake drying agent from falling off the cap, or placed at the bottom of the medicine bottle which has a circular locking notch to prevent the solid silica flake drying agent from falling out of the medicine bottle.
