Window Blinds Damper Segmented Pivoting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window blinds dampers rely on a single pivoting member, which is inefficient in quickly limiting the position of the pull cord and unstable in maintaining the position of window blinds.
Innovation Solution
A window blinds damper with a damping device featuring a main body with a damper housing, a first and second main body with pivots and securing rods, and a rewinding device that employs a cord to entangle in an S shape, increasing friction and stabilizing the position of the window blinds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single pivoting member is used to resist the pull cord, then the structure is simple, but the position limiting speed is slow and the position stability is poor
Solution Approach 1:
The damper structure is divided into two separate main bodies (first main body and second main body), each with its own pivoting member. This segmentation allows each component to independently contribute to position limiting, thereby increasing the speed and stability of position control without creating an overly complex integrated structure.

This segmentation allows each component to independently contribute to position limiting, thereby increasing the speed and stability of position control without creating an overly complex integrated structure.
3Reliability
If the cord is wrapped around multiple components in an S shape, then friction is increased and position stability is improved, but the device complexity increases
Solution Approach 1:
The cord is dynamically routed in an S-shaped path that engages with multiple moving components (first pivoting member, second pivoting member, and securing rod). This dynamic routing allows the cord to interact with multiple friction surfaces during operation, enhancing position stability while maintaining a relatively simple overall device structure.
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 solution effectively restricts the position of window blinds by increasing friction through an S-shaped entanglement of the cord, allowing for quick and stable adjustment of the blinds.
Implementation Method 1
The damper employs one end of a cord that passes above the securing axle, the securing spindles, wraps around the steering wheel lever, passes above the steering axle, and then passes through the through aperture

AI summary
A window blinds damper has at least one damping device, at least one damper, a rewinding device, and a plurality of slats. The damping device has a main body with a damper housing having a through aperture and a securing axle. The damper has a first main body and a second main body, the first main body having a first pivot for mounting in the damper housing, and the second main body having a second pivot for mounting in the first main body. The first main body further has a steering wheel lever, a steering axle, and a first securing rod, and the second main body further has two securing spindles and a second securing rod.
