Flexible Object Decorative Light Sewing Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching flexible and bendable light strands to flexible objects like clothes and banners are inefficient, as they are difficult to fix accurately and require manual adjustment, making production challenging and pattern arrangement inconsistent.
Innovation Solution
A flexible object with decorative light features a light strand and multiple threads, where the light emission diode units are electrically connected in series and sewn onto the flexible body using a sewing machine, allowing for precise arrangement and fixation of light patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adherence or sewing methods are used to attach light strands to flexible materials, then the light strands can be attached to the flexible object, but the light strands are difficult to fix accurately and require manual adjustment, making production challenging and pattern arrangement inconsistent
Solution Approach 1:
The invention divides the attachment process into two distinct parts: first, the light strand is pre-fixed to a template using hot melt adhesive in a controlled environment; second, the template with the pre-arranged light strand is then sewn to the flexible object. This segmentation allows accurate pattern arrangement to be achieved on the template before transfer to the final product, solving the contradiction between manufacturing precision and ease of manufacture.
Solution Approach 2:
The light strand is preliminarily arranged and fixed to the template before the actual attachment to the flexible object. This preliminary action on the template allows for precise pattern arrangement and adjustment in a controlled setting, eliminating the need for manual adjustment during final production and ensuring consistent pattern accuracy across multiple items.
2Manufacturing precision
If manual adjustment is used to position light strands, then the light strands can be arranged to form patterns, but the production process becomes time-consuming and labor-intensive
Solution Approach 1:
By separating the positioning function (performed on the template) from the attachment function (performed on the flexible object), the invention enables accurate light strand positioning to be achieved once on the template, which can then be replicated across multiple flexible objects through the sewing process, significantly improving productivity while maintaining positioning accuracy.
Solution Approach 2:
The template serves as an intermediary between the light strand and the flexible object. The light strand is first arranged and fixed on the template with high precision, then the entire template with the pre-arranged light strand is sewn to the flexible object. This intermediary approach eliminates the need for manual adjustment during final attachment, improving both positioning accuracy and production efficiency.
3Ease of manufacture
If hot melt adhesive is used to attach light strands to flexible materials, then the attachment can be achieved, but the flexible and bendable light strands are hard to be fixed and require manual position adjustment
Solution Approach 1:
The invention segments the attachment process into two stages: hot melt adhesive is used to fix the light strand to the template (where manual adjustment can be performed), and then sewing is used to attach the pre-fixed light strand to the flexible object. This segmentation allows the simplicity of adhesive application to be combined with the precision and permanence of sewing, eliminating the need for manual adjustment after attachment.
Solution Approach 2:
The template acts as an intermediary that allows hot melt adhesive to be used effectively. The adhesive is applied to fix the light strand on the template where it can be easily adjusted and positioned with precision. Once fixed on the template, the entire assembly is sewn to the flexible object, providing permanent fixation without requiring manual adjustment during final attachment.

AI summary
A flexible object has a flexible body being flexible and at least one decorative light attached to the flexible body and having a light strand and multiple threads. The light strand of each one of the at least one decorative light has a cord and multiple light emission diode units. The multiple light emission diode units are electrically connected to one another in series via the cord and are arranged along the cord. The multiple threads of each one of the at least one decorative light are sewed on the flexible body to fix the light strand of the decorative light to the flexible body. The multiple threads of each one of the at least one decorative light has a first thread wavily extending along and across the cord of the light strand of the decorative light.
