Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional safety system with multiple components is used, then the safety function is achieved, but the number of components increases leading to higher installation time and costs
Solution Approach 1:
The patent combines multiple safety system components into a single integrated electromagnetic safety trigger assembly. The electromagnetic component, magnetic brake, retention apparatus, and spring mechanism are merged into one unified device that performs the functions of traditional multi-component safety systems, thereby reducing component count while maintaining safety functionality.
Solution Approach 2:
The electromagnetic safety trigger assembly serves multiple functions within a single device: it acts as a safety trigger, a braking mechanism, and a positioning system. The magnetic brake can engage with the guide rail to stop the elevator car, while the electromagnetic component controls the positioning of the magnetic brake, and the spring provides resetting force, making the device multi-functional and reducing the need for separate components.
2Reliability
If traditional safety system components are used, then the safety operation is ensured, but installation time and costs increase
Solution Approach 1:
By merging multiple safety components into a single integrated assembly, the installation process is simplified. Instead of installing and coordinating multiple separate components, the unified electromagnetic safety trigger assembly can be installed as one unit, significantly reducing installation time while ensuring safety operation through its integrated design.
3Reliability
If traditional safety system components are used, then the safety function is achieved, but the system becomes less cost-effective
Solution Approach 1:
The integration of multiple components into a single electromagnetic safety trigger assembly reduces manufacturing costs by eliminating the need to produce, inventory, and assemble multiple separate parts. The unified design allows for more efficient manufacturing processes and reduces assembly operations, making the system more cost-effective while maintaining the required safety function.

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 solution reduces the number of components needed, enhancing cost-effectiveness and efficiency by using an electromagnetic safety trigger to control the braking system, effectively addressing the complexity and cost issues of traditional safety systems.
Implementation Method 1
an electromagnetic component, the electromagnetic component configured to move the magnetic brake from the rail-engaging position to the rail-non-engaging position upon receipt of a resetting signal
Implementation Method 2
the magnetic brake, when in the rail-engaging position contemporaneously with motion of the car, moving the rod in a direction to thereby move the safety brake from the non-braking state into the braking state
Implementation Method 3
the retention apparatus further includes a spring configured to move the electromagnetic component in a direction parallel to an actuation axis
