Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Roller blinds often suffer from uneven gaps on the left and right sides due to installation errors, and non-penetrating installations face issues with thread wear and difficulty in tightening, requiring complex tools for secure installation.
Innovation Solution
A gap-adjustable, quick non-penetrating installation roller blind design featuring sliders and grooves for lateral adjustment, an interference fit between sliders and grooves, and a button-operated mechanism for easy installation, ensuring even gaps and secure mounting without drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-penetrating installation mechanism is used, then wall damage is avoided and installation convenience is improved, but thread wear occurs and tightening becomes difficult requiring tools
Solution Approach 1:
The patent replaces the traditional threaded mechanical fastening system with a friction-fit system using a friction fit component that engages with a groove on the supporting rail. This substitution eliminates thread wear and the need for tool-assisted tightening while maintaining secure installation through friction and geometric constraints.
Solution Approach 2:
The patent extracts the problematic threaded fastening mechanism from the installation system and replaces it with a dedicated friction fit component that has a specific geometric shape complementary to the groove. This extraction removes the source of thread wear and simplifies the tightening operation to a simple insertion and friction-based securing.
2Ease of manufacture
If fixed roller blind mechanism is installed, then installation is simple, but gap uniformity deteriorates due to installation errors
Solution Approach 1:
The patent introduces dynamic adjustability to the otherwise fixed roller blind mechanism. The fabric can be laterally adjusted relative to the supporting rail through a controlled sliding mechanism, allowing the gaps to be equalized after installation. This dynamic adjustment capability compensates for installation errors while maintaining the simplicity of the overall fixed installation structure.
Solution Approach 2:
The patent segments the roller blind system into independently adjustable components - specifically, the fabric section can be adjusted relative to the supporting rail through the slider mechanism. This segmentation allows localized adjustment of gap uniformity without affecting the overall installation structure or requiring complex reconfiguration of the entire blind system.
3Manufacturing precision
If slider and groove cooperation is used for lateral adjustment, then gap uniformity is improved, but device complexity increases
Solution Approach 1:
The patent merges the adjustment function with the existing supporting rail structure by integrating the groove directly into the rail. The slider component is designed to fit within this groove, combining the adjustment mechanism with the structural support element. This merging approach provides gap adjustment capability while minimizing additional structural complexity.
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 design allows for even gaps on both sides of the curtain, enhances light-blocking effectiveness and aesthetics, and provides a convenient, quick installation process compatible with manual and electric control systems.
Implementation Method 1
The upper surface of the slider is equipped with spring pieces, which come into contact with the sliding surface of the groove and exert pressure on the groove through their own elastic force
Implementation Method 2
The slider engages with the groove through an interference fit

AI summary
The invention provides a gap-adjustable, quick non-penetrating installation roller blind, comprising a roller blind mechanism and a fixing mechanism. The fixing mechanism is supported between supporting walls and includes a non-penetrating installation mechanism and a supporting rail. A groove is provided at the lower end of the supporting rail. The roller blind mechanism is installed below the supporting rail, with a slider provided at the upper end of the roller blind mechanism. The roller blind mechanism achieves sliding relative to the supporting rail through the cooperation between the slider and the groove, and the slider and the groove prevent free sliding through interference fit or spring piece design. The invention allows the relative adjustment of the position of the curtain fabric after installation, ensuring even gaps on both sides and stable positioning of the curtain fabric by avoiding free sliding of the slider and the groove.
