Portable Disinfectant Sprayer Thumb-Press Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disinfectant spray containers are large and inconvenient to carry, limiting their use outside fixed locations, which increases the risk of virus infection due to inadequate hand disinfection opportunities.
Innovation Solution
A portable disinfectant sprayer with a compact design, featuring a housing with a liquid storage chamber, a nozzle for dispensing disinfectant, and a trigger assembly that allows for easy activation with a thumb-press mechanism, enabling hands-free disinfection on the go.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a cylindrical disinfectant spray container is used, then the liquid storage capacity is sufficient, but the device becomes large and inconvenient to carry
Solution Approach 1:
The patent applies nesting by placing the liquid storage chamber inside the housing cavity, with the storage chamber being selectively removable. The suction pipe extends from the storage chamber through the partitioning wall to the actuating manifold, creating a nested configuration where the storage chamber is contained within the overall device structure, optimizing space utilization while maintaining adequate liquid capacity.
2Reliability
If a fixed location spray container is used, then the disinfection function is reliable, but the device cannot be carried around for use outside fixed locations
Solution Approach 1:
The patent applies segmentation by dividing the device into distinct functional modules: a removable liquid storage chamber, a housing with actuating manifold, and a suction pipe connecting them. This modular segmentation allows the storage chamber to be selectively removed and refilled, while the main housing with the trigger assembly remains portable and can be carried anywhere, maintaining reliable disinfection function while improving portability.
3Device complexity
If a traditional spray container is used, then the structure is simple, but the operation requires hand washing facilities which are not always available
Solution Approach 1:
The patent applies self-service by incorporating a built-in liquid storage chamber that can be selectively removed and refilled, eliminating the need for external hand washing facilities. The device contains its own disinfectant supply, allowing users to perform hand disinfection anywhere without needing access to water or traditional washing facilities, while maintaining relatively simple structural 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
The portable sprayer allows for convenient and timely hand disinfection anywhere, reducing the risk of infection by providing a compact, easy-to-use solution for spraying disinfectant liquids.
Implementation Method 1
The actuating manifold, in response to a force applied to the sleeve, is configured to move from a rest position into a pressed position causing the nozzle to spray or dispense the liquid stored in the first chamber

AI summary
A portable sterilizing sprayer includes a gripper shaped shell, and a nozzle on the front surface of the shell. The back part of the shell includes a clamping device which can be clamped on the waist belt. The inner part of the shell presents a cavity to hold a disinfectant solution. The front end of the shell is provided with a pressing part for pressing the thumb, and when the pressing part is pressed, the disinfection in the liquid storage cavity is carried out. When it is used, it does not need to be removed, and the palm is pressed near the thumb and pressed with the thumb. The disinfecting liquid can be sprayed on the palm of the palm and can be sterilized at any time, so the portable disinfector is convenient to carry and to use it at any time.
