Engineering Contradiction Analysis
1Reliability
If conventional safety gates are held in positions between two walls or a door frame with bolts or tying ropes, then the safety gate can be securely positioned, but the installation process becomes laborious and time-consuming
Solution Approach 1:
The locking device is divided into separate functional components: a fixing member mounted on the gate body, a sliding member with guiding track, and a positioning member. This segmentation allows each component to perform its specific function independently, enabling tool-free installation while maintaining secure positioning through the coordinated action of these modular parts.
Solution Approach 2:
The locking device is designed to be self-installing without requiring external tools. The sliding member can be manually moved along the guiding track to engage the positioning member with the fixing member, allowing users to securely position the safety gate through simple manual manipulation of the device's own components.
2Area of stationary object
If conventional safety gates are made large in volume to provide adequate coverage, then the gate can effectively block access to dangerous locations, but the gate becomes difficult to store or transport
Solution Approach 1:
The gate body is segmented into multiple rods that can be collapsed or disassembled, reducing the volume when not in use while maintaining the ability to expand to adequate coverage size when installed. The locking device components are also separable, facilitating compact storage and easy transport.
Solution Approach 2:
The gate structure incorporates dynamic elements allowing it to transition between expanded and collapsed states. The rods and locking components can be reconfigured to minimize volume for transport while providing full coverage area when deployed, addressing both storage convenience and functional requirements.

AI summary
A safety gate has a gate body and at least one locking device. The at least one locking device is mounted on the gate body, and each has a fixing member, a sliding member, and a positioning member. The fixing member is tubular and has a closed end, at least one sliding protrusion, and a recess. The at least one sliding protrusion is formed on the closed end. The sliding member is mounted rotatably around the fixing member and has at least one guiding track and a holding hole. The at least one curved guiding track is formed on and protruding from an inner surface of the sliding member. Each guiding track has an inclined guiding surface to define a high end and a low end respectively at two ends of the guiding track.
