Inverted Cricket Water System Using Capillary Porous Medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water supply systems for crickets in enclosed spaces are prone to contamination due to the insects' urination and defecation, leading to frequent monitoring and replacement of water sources, which is labor-intensive and inefficient.
Innovation Solution
An inverted water system utilizing a porous and permeable medium at the bottom of a reservoir, allowing water to diffuse and moisten the surface, enabling crickets to drink from the bottom surface while preventing contamination through an elevated screen for access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional open dish-type water feeders are used, then crickets have easy access to water, but the water supply becomes contaminated by urination and defecation requiring frequent monitoring and replacement
Solution Approach 1:
The system inverts the conventional water feeder design by placing the water source at the bottom rather than in an open top dish. Crickets access water by landing on a screen above the water reservoir, where water is delivered to them through capillary action in porous material, preventing contamination from above.
Solution Approach 2:
A porous permeable material acts as an intermediary between the water reservoir and the crickets. This material allows water to pass through via capillary action while preventing direct contact between cricket waste and the water source, thus maintaining water cleanliness.
2Productivity
If open dish-type water feeders are used, then water is readily available to crickets, but labor-intensive monitoring and replacement is required
Solution Approach 1:
The system enables self-service water supply where water automatically flows from the reservoir through the porous material to the crickets via capillary action without requiring manual intervention for refilling or monitoring, significantly reducing labor time.
Solution Approach 2:
The water supply operates continuously through passive capillary action, eliminating interruptions for manual water changes and maintaining constant water availability to crickets without labor-intensive periodic replacement.
3Ease of operation
If water is provided in open containers, then crickets can easily drink, but bacterial, fungal, or microbial growth occurs
Solution Approach 1:
By inverting the water delivery system so water flows upward through porous material to meet the crickets on a screen, the design prevents cricket waste from falling into the water source, thereby eliminating the primary pathway for microbial contamination while maintaining drinking accessibility.
Solution Approach 2:
The porous permeable material serves as a protective intermediary barrier that allows water passage while blocking contaminants, preventing microbial growth by isolating the water source from cricket waste and reducing contamination risk.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a continuous, sanitized water supply to crickets, reducing the need for frequent water changes and maintaining a clean environment by allowing crickets to absorb water without contaminating their source.
Implementation Method 1
as water fills the container, the water diffuses through the medium and moistens the bottom surface of the medium
Implementation Method 2
water (or other selected liquids) migrates through a water-retaining porous and permeable material at a controlled rate

AI summary
The insect water supply system is configured to prevent the insects (such as crickets) from self-contaminating the water supplied to the insects' rearing enclosure. The system is designed so that the insects drink in an inverted (i.e. upside down) and elevated position—consequently the insects' feces fall downward toward the ground and away from their water source—and therefore do not contaminate the insects' water supply.
