Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swimming pool cover technologies are costly, prone to leaks, and lack visual appeal, with complex sealing requirements and high production expenses due to specialized materials and coatings.
Innovation Solution
A closure arrangement featuring base elements with hollow chambers and a connecting mechanism, using lightweight materials with a density between 0.01 and 0.7 g/cm3, and a spacer layer for buoyancy and color options, along with a non-positive fixing element for easy assembly and tool-free adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hollow chambers are sealed watertight with complex sealing devices, then liquid-tight sealing is improved, but manufacturing cost and device complexity increase significantly
Solution Approach 1:
The invention extracts the sealing function from complex internal sealing devices and relocates it to simple end caps that close the hollow chambers. This removes the need for complex piston plates and elastic fillers, achieving watertight sealing through simple cap closure while dramatically reducing device complexity
Solution Approach 2:
Instead of sealing the hollow chambers from the sides or bottom using complex internal mechanisms, the invention inverts the approach by sealing them from the ends using simple caps. This reversal of sealing direction simplifies the sealing mechanism while maintaining liquid-tight reliability
2Illumination intensity
If specialized coatings and colors are applied to roller shutter slats, then visual appeal is improved, but manufacturing cost increases
Solution Approach 1:
The base elements serve multiple functions: structural support, buoyancy through hollow chambers, and aesthetic appearance through color integration. The coloring is incorporated into the base element material itself rather than requiring separate coating processes, achieving visual appeal without additional manufacturing complexity or cost
Solution Approach 2:
The invention merges the structural base element with the aesthetic coating by integrating color directly into the base element material. This combination eliminates separate coating processes and reduces manufacturing steps while maintaining visual appeal
3Reliability
If connection devices require additional securing against longitudinal displacement, then connection reliability is improved, but assembly complexity and time increase
Solution Approach 1:
The connecting devices are designed with built-in features such as recesses and protrusions that automatically align and secure base elements in the correct position during assembly. This self-aligning design eliminates the need for additional securing operations while ensuring connection stability, reducing assembly time without compromising reliability
