Two-Way Locking Door Stop with Rotatable Lock Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door stops can only achieve one-way locking, which is insufficient for applications requiring two-way locking, such as homes with pets or infants where ventilation or finger protection is necessary.
Innovation Solution
A two-way locking door stop with a base that includes a telescopic member and a lock body that can be rotated between two states, allowing for locking and unlocking mechanisms to secure the door leaf in both opening and closing directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a door stop uses a fixed structure mounted on the door leaf, then it can achieve one-way locking, but it cannot achieve two-way locking
Solution Approach 1:
The lock body is designed to rotate between a first state (downward parallel to the first surface) and a second state, transforming a static structure into a dynamic one. This rotation mechanism enables the door stop to adapt to different locking directions (opening and closing) while maintaining a relatively simple overall structure.
Solution Approach 2:
The door stop is designed to perform multiple functions: it can lock the door leaf in both opening and closing directions by rotating the lock body between two states. The same basic structure serves both locking directions, eliminating the need for separate mechanisms for each direction.
2Adaptability or versatility
If a door stop uses a rotatable lock body between two states, then it can achieve two-way locking, but the structure becomes more complex
Solution Approach 1:
The door stop is divided into distinct functional components: a base with a base main body and telescopic member, and a separate lock body that rotates. The locking mechanism is further segmented into a first locking member on the base and a second locking member on the lock body. This segmentation allows each component to perform its specific function independently, simplifying the overall design despite the added rotational capability.
3Force
If the lock body is arranged downward parallel to the first surface in the first state, then it provides sufficient locking force for two-way locking, but it increases the distance the lower end protrudes from the door leaf surface
Solution Approach 1:
The lock body rotates between two states: in the first state it is arranged downward parallel to the first surface to provide sufficient locking force, and in the second state it is arranged upward parallel to the first surface to minimize protrusion. This dynamic repositioning allows the same component to satisfy both requirements at different times.
