Heart-Shaped Rod Locking Member with Speed Regulation Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking members fail to effectively restrict the movement of rods with high entering speeds, leading to unreliable locking of doors in open states, as they lack a mechanism to regulate the rod's speed.
Innovation Solution
Incorporating a speed regulation path portion that extends vertically and includes rod receiving portions at its edges to fluctuate and slow down the rod, ensuring it is locked by a locking portion, thereby preventing the rod from moving out of the path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking member is designed to lock a rod in a path, then the door can be locked in an opened state, but the locking member cannot reliably restrict movement of the rod when the entering speed is high
Solution Approach 1:
The speed regulation path portion is designed to slow down the rod before it reaches the locking portion. This preliminary action of reducing speed ensures that the locking mechanism can effectively engage with the rod even when it enters at high speed, thereby resolving the contradiction between handling high speed entries and ensuring reliable locking.
Solution Approach 2:
The speed regulation path portion acts as an intermediary between the rod's high-speed entry and the locking portion. It mediates the rod's motion by regulating its speed, allowing the locking mechanism to function reliably without being directly exposed to the full impact of high-speed entries.
2Device complexity
If the locking member has a simple path structure, then the device complexity is low, but the rod cannot be regulated to fluctuate and slow down
Solution Approach 1:
The path is segmented into two distinct functional portions: a speed regulation path portion and a locking portion. This segmentation allows the speed regulation function to be integrated into the path structure itself without adding separate complex mechanisms, thus maintaining simplicity while achieving reliable speed regulation.
Solution Approach 2:
The speed regulation path portion serves multiple functions: it guides the rod, regulates its speed, and causes it to fluctuate. By making this path portion multi-functional, the invention avoids adding separate dedicated speed regulation mechanisms, thereby maintaining low device complexity while achieving reliable speed control.
