Solution Overview
Problem
Existing trigger pump dispensers lack efficient spray characteristics, require high trigger actuation force, and have complex designs with numerous parts, making them difficult to manufacture and maintain.
Innovation Solution
A simplified trigger pump dispenser design featuring a cam and cam follower mechanism that reduces trigger actuation force by transforming pivoting motion into linear piston movement, allowing for interchangeable pump bodies and decorative hoods, and a base that securely attaches to the fluid reservoir with deformable locks for easy interchangeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional trigger pump designs are used, then spray function is provided, but trigger actuation force is high and spray efficiency is insufficient
Solution Approach 1:
The patent applies dynamics by making the trigger mechanism movable and adjustable. The trigger pivots about a pivot point and can be positioned at different locations along the longitudinal axis of the pump body, allowing optimization of the mechanical advantage and actuation force based on specific application requirements while maintaining spray functionality.
Solution Approach 2:
The patent introduces a new dimension of adjustment by allowing the trigger pivot point to be repositioned along the longitudinal axis. This dimensional adjustment capability enables optimization of the trigger arm leverage, reducing actuation force while improving spray efficiency through better mechanical advantage.
2Reliability
If complex designs with numerous parts are used, then pump function is achieved, but manufacturing difficulty increases and maintenance becomes difficult
Solution Approach 1:
The patent segments the pump into distinct functional components: a pump body, a separately attachable trigger assembly, and an interchangeable fluid reservoir. This segmentation allows each component to be manufactured independently using optimized processes and simplifies assembly and maintenance operations.
Solution Approach 2:
The patent creates universal components that can serve multiple functions. The trigger assembly with its adjustable pivot point can accommodate different trigger positions and configurations. The pump body design with standardized attachment features allows it to work with various fluid reservoir types, reducing the need for application-specific custom parts.
3Stability of the object's composition
If fixed pump body designs are used, then structural stability is maintained, but adaptability to different pump types and appearances is limited
Solution Approach 1:
The patent applies dynamics by making the pump system configurable and adaptable. The trigger pivot point can be repositioned along the longitudinal axis to optimize performance for different applications. The deformable lock mechanism allows for easy attachment and detachment of components, enabling the system to adapt to different operational requirements while maintaining structural integrity during use.
Solution Approach 2:
The patent segments the pump system into independently replaceable components. The pump body can be detached from the fluid reservoir using the deformable lock mechanism, allowing different pump bodies or reservoirs to be interchangeably attached. This segmentation maintains structural stability during operation while providing versatility for different applications and appearances.
