Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety equipment for train platforms faces difficulties in uniformly adjusting and maintaining the tension of long ropes due to cumbersome bolt-based systems and temperature-related issues, leading to inefficiencies and safety concerns.
Innovation Solution
A rope tension adjustment unit is introduced, featuring support shafts and elastic members that move sub-blocks to adjust rope tension, allowing for uniform tension maintenance across rope lengths of tens to hundreds of meters, with guide shafts ensuring smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a plurality of bolts and much rope are used to adjust rope tension, then the rope tension can be adjusted, but the efficiency of maintenance is low and it is troublesome and inconvenient
Solution Approach 1:
The block is divided into an outer block and an inner block that can move relative to each other. The inner block is segmented from the outer block and can be displaced along the support shaft, allowing independent adjustment of rope tension without affecting the entire assembly. This segmentation enables simple tension adjustment by moving only the inner block.
Solution Approach 2:
The tension adjustment function is extracted from the traditional bolt-based system and implemented through the relative movement between the inner and outer blocks. The inner block can be taken out or displaced from its initial position to adjust tension, eliminating the need for multiple bolts and complex adjustment procedures.
2Adaptability or versatility
If a spring is disposed inside the rope to adjust tension, then some tension adjustment is possible, but it is difficult to appropriately adjust the tension in accordance with extension and contraction of the rope due to changes in season and temperature
Solution Approach 1:
The inner block is designed to move dynamically along the support shaft in response to rope extension and contraction caused by seasonal and temperature changes. This dynamic adjustment mechanism allows the system to automatically adapt to environmental variations while maintaining appropriate tension, unlike a fixed spring-based system.
Solution Approach 2:
The system allows for manual parameter changes by displacing the inner block to different positions along the support shaft. This enables operators to adjust the tension parameters according to seasonal variations and rope extension/contraction, providing adaptability that a fixed spring system cannot achieve.
3Length of stationary object
If a spring is used to adjust rope tension, then some tension control is achieved, but for ropes with length of tens to hundreds of meters, it is difficult to adjust the tension and there are constraints in function
Solution Approach 1:
The block assembly is segmented into outer and inner blocks, with the inner block capable of independent movement along the support shaft. This segmentation allows the tension adjustment mechanism to effectively handle long ropes (tens to hundreds of meters) by providing a simple, localized adjustment point that does not depend on the overall rope length, unlike spring-based systems.
4Manufacturing precision
If bolts are used to adjust rope tension, then the rope can be tensioned, but it is difficult to uniformly adjust and maintain the tension of the rope
Solution Approach 1:
The block is segmented into an outer block and an inner block that move relative to each other along a support shaft. This segmentation allows for uniform tension adjustment across the entire rope by providing a centralized adjustment mechanism (inner block displacement) that affects the entire rope system uniformly, rather than requiring multiple bolt adjustments at different locations.

AI summary
The present invention provides safety equipment for a train platform, in which sub-blocks (150) are disposed inside blocks (120) and connected by rope (200) that circulates and rope tension adjustment unit each have a tension adjustment unit (300) disposed between the block (120) and the sub-block (150) to adjust tension of the rope (200) by moving outward the sub-block (150). Accordingly, it is possible to uniformly adjust tension of the rope, to prevent a safety accident of passengers entering and exiting by easily opening the rope by uniformly maintaining the tension of the rope, and to be efficiently used through a simple structure and easy maintenance.
