Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous strips for outdoor equipment, such as hammocks, are costly due to complex circuit designs, prone to detachment, and cumbersome to install, with traditional light strings requiring sewing and using plastic tubes that slide easily.
Innovation Solution
A luminous strip comprising a light-transmitting strip with a light-guiding core and fixing base, where LED elements are positioned at ends, guiding light through the core strip and transmitted via the strip, with a simple sewing method for secure attachment to fabric.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional light strings with multiple connected light-emitting units are used, then illumination coverage is improved, but device complexity and cost increase due to complex circuit design
Solution Approach 1:
The patent extracts the light-emitting function from multiple distributed LEDs and concentrates it into a single LED located at one end of the light-guiding core strip. The light is then guided along the entire length of the strip through optical conduction, eliminating the need for complex circuits connecting multiple light-emitting units while maintaining comprehensive illumination coverage.
Solution Approach 2:
The patent introduces a light-guiding core strip as an intermediary between the single LED light source and the light-transmitting portion. This core strip conducts light from the single LED along its length, enabling uniform illumination without requiring multiple LEDs or complex circuitry, thus resolving the contradiction between illumination coverage and device complexity.
2Strength
If plastic tubes are used to contain the light string, then protection is provided, but reliability decreases due to easy detachment and sliding
Solution Approach 1:
The patent merges the light-guiding core strip with the light-transmitting portion into an integrated structure where the core strip is inserted into a channel of the light-transmitting portion. This integration eliminates the separate plastic tube containment, providing both protection and reliable fixation through the structural integration and friction fit within the channel.
3Reliability
If sleeves are sewn along fabric edges and plastic tubes inserted for fixation, then secure attachment is achieved, but ease of manufacture deteriorates due to cumbersome and time-consuming installation
Solution Approach 1:
The patent combines the light-guiding core strip, light-transmitting portion, and fixation structure into a single integrated luminous strip assembly. The connecting portion with sheet-like edge can be directly sewn to fabric edges without requiring separate sleeve attachment and tube insertion steps, significantly simplifying the manufacturing process while maintaining secure attachment.
Solution Approach 2:
The connecting portion of the light-transmitting strip serves multiple functions: it provides structural connection to the fabric edge through sewing, acts as a fixation mechanism through its sheet-like edge design, and maintains the integrity of the light-transmitting structure. This multi-functionality eliminates the need for separate fixation components and complex installation steps.
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
Reduces the number of LEDs needed, provides uniform illumination without bright spots, and ensures a firm connection, making installation easier and more secure.
Implementation Method 1
The light-guiding core strip is made of transparent plastic material with light-guiding properties. The light emitted by the LED elements enters the light-guiding core strip from its end, causing the light-guiding core strip to emit light
Implementation Method 2
the light emitted by the LED elements enters the light-guiding core strip from its end, causing the light-guiding core strip to emit light, which is then transmitted through the light-transmitting portion of the light-transmitting strip

AI summary
A luminous strip for outdoor equipment, comprising a light-transmitting portion and a connecting portion. The light-transmitting portion has an axial channel for the passage of a light-guiding core strip. The connecting portion extends laterally from the side of the light-transmitting portion, forming a thin sheet-like edge for connection to outdoor equipment. The light-guiding core strip is made of transparent plastic material with light-guiding properties. Light emitted by LED light-emitting elements enters the end of the light-guiding core strip, causing the core strip to emit light. The light generated on the surface of the core strip is transmitted through the light-transmitting portion of the light-transmitting strip. the luminous strip emits light through the light-guiding core strip, with the LED light-emitting elements positioned at the end of the core strip. This reduces the number of LEDs required as the light source.
