Pressing Pump Locking Mechanism to Prevent Head Rotation and Overflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressing pumps are prone to liquid overflow during transportation due to the pressing head rotating and separating from the locking cover, and the spring member becomes compressed for extended periods, leading to insufficient resilience and poor user experience.
Innovation Solution
A pressing pump design featuring a floating member with two height positions and a linkage locking mechanism that stabilizes the pressing head, preventing rotation and enabling liquid discharge only when necessary, using perforated guide grooves and rotating members to control the floating member's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressing head is connected to the locking cover in a threaded mode to allow screwed-in and screwed-out states, then the pressing head can move up and down for normal use, but the pressing head is prone to rotation due to collision during transportation, causing separation from the locking cover and liquid overflow
Solution Approach 1:
The patent introduces a floating member that can dynamically change its position between a first position (for transportation stability) and a second position (for liquid discharge operation). This dynamic positioning system allows the pressing head to be stable during transport while maintaining operational capability when needed, resolving the contradiction between stability and ease of operation.
Solution Approach 2:
The floating member acts as an intermediary between the pressing head and the locking cover. It provides a buffer zone that prevents direct rotational transmission from the pressing head to the locking cover, thereby preventing separation while still allowing controlled movement for liquid discharge.
2Ease of operation
If a spring member is provided between the pressing head and the locking cover to enable reciprocating movement, then the pressing head can move up and down for normal use, but the spring member is in a compressed state for a long time during transportation, resulting in insufficient resilience and affecting user experience
Solution Approach 1:
The floating member's dynamic positioning between first and second positions allows the spring member to alternate between compressed and relaxed states. During transportation (first position), the spring is compressed but the system is stable. During operation (second position), the spring can relax and provide adequate resilience for pressing head movement, thus maintaining both operational capability and spring reliability.
Solution Approach 2:
The system employs periodic action by alternating between transportation mode (spring compressed) and operation mode (spring relaxed) through the floating member's position changes. This periodic switching prevents continuous compression of the spring member, maintaining its resilience for reliable operation when needed.
3Adaptability or versatility
If the pressing head is allowed to rotate freely to enable liquid discharge function, then the pressing head can be pressed for liquid discharge, but the pressing head may rotate and separate from the locking cover during transportation, causing liquid overflow
Solution Approach 1:
The floating member's dynamic position adjustment creates two distinct operational states: a locked state during transportation that prevents rotation and liquid overflow, and an unlocked state during operation that allows rotation and pressing for liquid discharge. This dynamic control resolves the contradiction between adaptability and harmful factor prevention.
Solution Approach 2:
The linkage locking mechanism provides preliminary anti-action by preventing rotation of the pressing head before transportation begins. The floating member is positioned in the first position that engages the locking mechanism, proactively preventing the harmful effect of rotation and liquid overflow before it can occur.
