Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting warning ropes pose health risks due to mercury, lack integration with the camp rope, and have low luminous efficiency, making them unsafe and inefficient for use in camping environments.
Innovation Solution
A light-emitting warning rope design featuring a light-emitting core with a light guide strip and nodes, surrounded by bearing yarns and outer covering yarns with fluorescent dye, integrated within a structural rope and light-transmitting sleeve, allowing for tension resistance and efficient light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a cold cathode fluorescent lamp (CCFL) is used to fabricate a soft luminescent tube, then the luminescent tube can emit cold light to warn users about the camp rope position, but it contains mercury which creates potential safety hazards
Solution Approach 1:
The patent extracts and removes the harmful mercury-containing CCFL from the system, replacing it with a safe LED light source that provides the same warning function without mercury leakage risks
Solution Approach 2:
The patent uses LEDs which are solid-state, durable, and environmentally friendly compared to fragile CCFL tubes containing mercury, providing a safer and more reliable long-term solution
2Illumination intensity
If a luminescent tube is used as an additional device, then it can provide warning light function, but it is hardly integrated with the camp rope and not easy to use
Solution Approach 1:
The patent merges the light-emitting function directly into the camp rope structure by embedding LEDs within the rope's braided layers, creating an integrated unit that combines mechanical support and warning light functions in a single component
Solution Approach 2:
The camp rope is designed to serve multiple functions simultaneously: structural support through bearing yarns and warning indication through integrated LEDs, eliminating the need for separate luminescent tube devices
3Illumination intensity
If a luminescent tube with insufficient luminous efficiency is used, then it can provide some warning light, but it must waste a lot of power to exhibit sufficient brightness
Solution Approach 1:
The patent changes the light source parameters from inefficient CCFL to high-efficiency LED technology, which provides superior luminous efficiency and reduces power consumption while maintaining or improving warning light brightness
Solution Approach 2:
The patent replaces the gas-filled CCFL system with solid-state LED technology, achieving higher energy efficiency and lower power consumption for the same or better illumination output
4Strength
If bearing yarns are made longer to withstand axial tension, then the rope can bear more tension, but the light-emitting core becomes relatively shorter and may not provide sufficient light coverage
Solution Approach 1:
The patent segments the light-emitting function into multiple discrete LED nodes distributed along the light guide strip, ensuring adequate light coverage even when the bearing yarns are extended for higher tension capacity
Solution Approach 2:
The patent introduces a light guide strip as an intermediary component that efficiently distributes light from LED nodes along the length of the rope, maintaining uniform light coverage despite variations in rope length and tension requirements
Applied Scientific Principles
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 rope provides a safe, integrated, and energy-efficient warning system that can withstand tension and enhance visibility in low-light camping conditions, reducing the risk of accidents by clearly indicating the rope's position.

AI summary
A light-emitting warning rope (100) is provided with one end integrated to a tent (200) and other end integrated to an anchoring point (300). The light-emitting warning rope (100) is disposed between the anchoring point (300) and the tent (200) to provide a tension to set the tent (200) upright. The rope comprises a light-emitting core (10) and a structural rope (20). The structural rope (20) comprises a plurality of bearing yarns (21) which is knitted into a strip body with the light-emitting core (10) as an axis, and the strip body knitted by each bearing yarn is knitted in a mesh shape on the radial side and has a plurality of gaps through which light from the light-emitting core (10) is transmitted. In any segment of the rope, the light-emitting core (10) has a stretching length less than that of each bearing yarn, so that the axial tension acts substantially on the bearing yarns (21) when the rope suffers an axial tension.
