Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems face challenges in providing flexible and safe access to the electric lines of measurement tapes for information transmission and power supply, especially across multiple floors, which is crucial for position determination and safety mechanisms.
Innovation Solution
A connecting device that acts as a guide bracket for measurement tapes, featuring openings for reading markings and integrated communication lines, with various contact types such as piercing, crimping, spring-loaded, inductive, and capacitive connections, allowing flexible access and ensuring safety by bridging or interrupting lines as needed, and including a connection test device for rapid maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cable routing is passed through the elevator shaft in cable shafts, then the electric lines are protected and organized, but access to the lines for information gathering, power tapping, and maintenance becomes difficult and inflexible
Solution Approach 1:
The measurement tape is segmented into multiple sections with individual access points at different floors. The guide bracket system allows selective access to specific segments of the measurement tape without disrupting the entire cable routing system, enabling floor-by-floor maintenance and connection establishment while preserving overall system integrity
Solution Approach 2:
The guide bracket acts as an intermediary device between the measurement tape and the elevator shaft structure. It provides a stable mounting mechanism that facilitates easy access to the measurement tape lines through integrated openings and contact elements, while maintaining the protective cable shaft routing structure
2Adaptability or versatility
If access to measurement tape lines is enabled at multiple positions for flexible information gathering and power tapping, then adaptability and ease of operation improve, but the risk of malfunctions and safety issues increases
Solution Approach 1:
The guide bracket is pre-configured with safety contact elements and interruption devices that are ready to detect malfunctions and execute safety protocols. The system includes pre-installed connection contacts and bridging mechanisms that automatically activate safety functions when measurement tape line interruptions are detected, preventing harmful effects before they can propagate
Solution Approach 2:
The guide bracket incorporates feedback mechanisms through safety contact elements that continuously monitor the integrity of measurement tape lines. When a line interruption or malfunction is detected, the system provides immediate feedback through the safety device, which can then interrupt the elevator drive or activate alarm signals to prevent unsafe operation
3Reliability
If multiple connection contacts and safety devices are integrated into the guide bracket, then safety and reliability improve, but device complexity increases
Solution Approach 1:
Multiple functions are merged into a single integrated guide bracket structure. The guide bracket combines mechanical guidance, electrical contact elements, safety monitoring, and interruption capabilities in one unified component, reducing the need for separate devices and simplifying the overall system architecture while maintaining high safety standards
Solution Approach 2:
The guide bracket is designed as a universal device that performs multiple functions: guiding the measurement tape, providing access openings for different floors, establishing electrical connections through contact elements, detecting malfunctions, and executing safety protocols. This multi-functionality reduces the number of separate components needed in the system
