Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for body care and beauty products are not compact enough to fit aesthetically with small bottles, and they often require complex mechanisms that increase costs and component count.
Innovation Solution
A compact dispensing device with a multifunctional plastic dispensing head that includes a socket, main body, chassis, piston, and trigger group, featuring a pre-compression valve and non-return valve for precise dosing and venting, allowing for efficient dispensing of small quantities while maintaining a sleek design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a compact dispensing head design is used, then aesthetic appeal and cost-effectiveness are improved, but dispensing functionality and reliability may be compromised
Solution Approach 1:
The patent combines multiple dispensing components (socket, main body, chassis, piston, trigger group, valves) into a single integrated dispensing head assembly that fits within the bottle neck compartment. This merging of components achieves compactness while maintaining all necessary dispensing functions through careful spatial arrangement and functional integration.
Solution Approach 2:
The dispensing head components are nested within each other and within the bottle neck compartment. The socket receives the main body, which contains the chassis, piston, and valve mechanisms. This nested arrangement maximizes space utilization and achieves compact design without sacrificing functionality.
2Measurement precision
If multiple components are used for precise dosing and venting, then dispensing precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The piston serves multiple functions: it acts as a dosing mechanism to control product quantity, a sealing element to prevent leakage, and a driving force for product dispensing. The integrated valve system provides both pre-compression and non-return functions within a unified structure, reducing component count while maintaining dosing precision.
Solution Approach 2:
The pre-compression valve and non-return valve are integrated into a single valve system within the dispensing head. This merging of valve functions reduces the number of separate components while maintaining precise control over product dosing and flow direction.
3Object-generated harmful factors
If valves are integrated into the dispensing head, then accidental leakage is prevented, but manufacturing complexity increases
Solution Approach 1:
The pre-compression valve and non-return valve are merged into a single integrated valve assembly within the dispensing head. This integration prevents leakage by ensuring proper sealing and one-way flow control, while the unified structure simplifies manufacturing compared to assembling multiple separate valve components.
Solution Approach 2:
The integrated valve system performs multiple functions (pre-compression and non-return) within a single component structure, preventing leakage through coordinated action of its sealing elements while reducing the number of separate manufacturing operations required.

AI summary
A dispensing device (1) comprises a bottle (2) provided with a neck (8) and a trigger dispensing head (4) fitted to the neck (8). The dispensing head comprises a socket (20) at least partially housed in the neck compartment (10), a main body (40) which, with said socket (20), delimits a valve compartment (100) in the neck (8), a valve group (110), a piston (120), a chassis (70), a trigger group (140) and elastic return means. The valve group (110) is contained in the valve compartment (100), thus limiting the overall size of the device (1).
