Hygienic Disposal Pants with Suction and Foam Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for hygienic disposal of human waste, such as diapers, are uncomfortable to wear for extended periods and pose hygiene risks due to bacterial contact, especially for individuals unable to use toilets or wear protective suits.
Innovation Solution
The device features pants made of gas- and liquid-tight, elastic material with open-pore foam inserts in the waist band and leg bands, allowing air flow and equipped with annular nozzles for liquid and gas introduction to facilitate drainage, cleaning, and disinfection, using a suction hose for waste removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diapers are used for temporary storage of excrement, then excrement can be contained close to the body, but excrement remains in contact with the wearer's skin for a long time causing hygiene issues and discomfort
Solution Approach 1:
The invention extracts the excrement immediately from the body area by directing it through a suction hose to an external disposal container, removing the harmful substance before it can remain in contact with the skin for extended periods, thus resolving the contradiction between hygiene safety and wearing comfort
Solution Approach 2:
The device performs preliminary cleaning action by introducing liquid through nozzles to rinse and disinfect the skin surface after excrement removal, preventing bacterial contact and discomfort before they can occur, thereby maintaining both hygiene safety and comfort
2Ease of operation
If open-pore foam inserts are added to waistband and leg cuffs, then air flow is enabled for hygiene and comfort, but device complexity increases
Solution Approach 1:
The invention uses open-pore foam inserts in the waistband and leg cuffs that allow air permeability, enabling breathability and comfort without requiring complex mechanical ventilation systems, thus improving wearing comfort while adding minimal structural complexity
Solution Approach 2:
The open-pore foam structure provides self-regulating air flow that automatically adjusts to the wearer's needs without requiring external control mechanisms, achieving comfort enhancement with minimal added complexity
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
Ensures comfortable, hygienic disposal of waste over long periods without the drawbacks of diapers, maintaining skin health and reducing bacterial contact through air flow and liquid/gas management.
Implementation Method 1
the nubs or foam on the inside of the trousers create a defined, air-permeable space between the skin and the trousers. This allows air or another gas to be introduced into the interior through the open-cell foam at the waistband and leg cuffs
Implementation Method 2
The airflow or gas then dries the skin. The liquid inlet can be used to introduce either water or a cleaning fluid into the interior, aiding in the removal of waste products and cleansing and disinfecting the skin
