Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spraying devices rely on propellants, electricity, or compressors, making them large, heavy, difficult to transport, and unsafe, and they cannot simultaneously dispense two liquids with overlapping trajectories, particularly for environmentally friendly products and liquids that cannot be pressurized or hand-pumped.
Innovation Solution
A spring-loaded spraying device with canister assemblies, springs, and a locking mechanism that allows for simultaneous dispensing of two liquids with overlapping trajectories without propellants or electricity, using a handle and trigger assembly to control liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If propellants, electricity, or compressors are used to power liquid dispersion, then spraying capability is achieved, but device size increases, weight increases, and safety risks increase
Solution Approach 1:
The patent removes harmful propellants, electrical components, and compressor systems from the spraying device, replacing them with a simple spring-loaded mechanical system. This extraction of dangerous elements achieves the safety improvement while reducing device complexity and weight.
Solution Approach 2:
The spring-loaded mechanism provides self-contained mechanical energy storage and release, eliminating the need for external power sources like electricity or gas propellants. The device serves itself through the stored mechanical energy in the spring, improving safety without requiring additional heavy equipment.
2Adaptability or versatility
If traditional spraying devices are used, then single liquid dispensing is achieved, but simultaneous dispensing of multiple liquids with overlapping trajectories is not possible
Solution Approach 1:
The device divides the dispensing system into separate canister assemblies, each capable of holding and dispensing a different liquid. Multiple canisters are positioned to create overlapping spray trajectories, enabling simultaneous multi-liquid dispensing while keeping each individual canister assembly relatively simple in structure.
Solution Approach 2:
The device design allows multiple canister assemblies to share common structural elements and mounting mechanisms, creating a universal platform that can handle multiple liquids. The overlapping trajectory design enables different liquid combinations to be dispensed simultaneously from the same device structure.
3Ease of operation
If aerosol sprays are used for portability, then portable dispensing is achieved, but product capacity is limited and safety risks increase due to explosive propellants
Solution Approach 1:
The patent removes explosive gas propellants from the canister assemblies, replacing them with spring-loaded mechanical actuation. This extraction eliminates the safety hazards associated with aerosol propellants while maintaining the portable, handheld form factor of the device.
Solution Approach 2:
The spring-loaded mechanism provides dynamic, on-demand actuation of the liquid dispensing process. Users can control the timing and duration of spray bursts by manually triggering the spring release, enabling portable operation with larger product capacities that would be unsafe in traditional aerosol containers.
