Liquid Dispensing Container Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid-agent dispensing containers with leveraged structures provide an operational feeling different from those with direct head portion pushing, leading to unfavorable user experience due to the swinging of the operating portion.
Innovation Solution
A liquid-agent dispensing container design that employs a pivotally supported swing portion and a guide mechanism to transfer pressing forces to the head portion, allowing the operating portion to move independently and maintain posture, mimicking the operational feel of direct head portion pushing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a pivotally supported swing portion is used to transfer pressing force to the head portion, then the force required to dispense liquid is reduced, but the operating portion swings and provides unfavorable operational feeling
Solution Approach 1:
The patent introduces a guide mechanism as an intermediary component between the operating portion and the swing portion. This guide mechanism includes guiding grooves and guided ribs that constrain the operating portion's movement path, preventing unwanted swinging while still allowing the leverage mechanism to reduce the dispensing force. The intermediary guide structure mediates between the force-reducing swing mechanism and the user's operational expectations.
2Stability of the object's composition
If the operating portion is allowed to move independently to maintain posture, then operational stability is improved, but the device complexity increases due to additional guide mechanisms
Solution Approach 1:
The patent segments the operating portion into functionally distinct elements: the operating portion itself, the swing portion, and the guide mechanism with separate guiding portions and guided portions. This segmentation allows each component to perform its specific function independently - the guide mechanism maintains stability while the swing portion provides force multiplication, reducing overall system complexity through functional decomposition.
Solution Approach 2:
The patent implements a dynamic guide mechanism where the guiding grooves and guided ribs allow controlled movement of the operating portion while maintaining posture. Rather than rigidly fixing the operating portion, the dynamic interaction between the guiding and guided elements provides the necessary constraints while permitting the leverage action, achieving stability without excessive 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 design achieves an operational feeling similar to direct head portion pushing while reducing the force required to dispense liquid agents, enhancing user experience and stability during use.
Implementation Method 1
a swing portion (160) that is pivotally supported at a pivotally supporting portion (91) in a swingable manner relatively to the mounting portion (52)... an acting portion (165a, 33) that is located between the force application portion (161) and the pivotally supporting portion (91), and transfers a pressing force from the swing portion (160) to the head portion (30)

AI summary
A liquid-agent dispensing container (100) includes: a mounting portion (52) that is mounted on a container body (10); a swing portion (160) that is pivotally supported in a swingable manner with respect to the mounting portion (52) and has a force application portion (161) that receives a pressing force; an operating portion (20) that has a pressing portion that presses the force application portion (161) when pressed; an acting portion that transfers a pressing force from the swing portion (160) to a head portion (30) when the force application portion (161) is pressed; and a guide mechanism that guides a relative movement of the operating portion (20) with respect to the head portion (30) while maintaining a posture of the operating portion (20) when the operating portion (20) is pressed. At least a part of the head portion (30) is covered with the operating portion (20) when the liquid-agent dispensing container (100) is viewed in a direction in which the head portion (30) is pressed with respect to the mounting portion (52).
