Spindle-Type Holder for Vertical Blind Vane Slope Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical venetian blind vane holders are inadequate for sloped or arched architectural openings, as they require specific lengths that do not accommodate varying slope angles, leading to suboptimal performance and aesthetic issues, and existing adjustable solutions are difficult to control and prone to over-adjustment.
Innovation Solution
A length-adjustable vane holder with a threaded spindle element and spindle nut design, allowing vertical displacement and rotation to achieve precise length adjustments, featuring a locking mechanism to prevent inadvertent rotation during tilting, enabling easy and reliable adjustment of the vane holder's length without compromising radial orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length vane holder is used, then the manufacturing and inventory process is simplified, but the holder cannot accommodate varying slope angles, leading to suboptimal performance and aesthetic issues
Solution Approach 1:
The vane holder employs a telescopic mechanism with movable sections that can extend or retract to change the holder's length dynamically. This allows the same holder to adapt to different slope angles by adjusting its length, transforming a static structure into a dynamic one that responds to varying installation requirements.
Solution Approach 2:
The holder is divided into multiple telescopic sections that can move relative to each other. This segmentation allows independent adjustment of each section's position, enabling precise length control to match different slope angles while maintaining a compact form when retracted.
2Adaptability or versatility
If an adjustable vane holder mechanism is implemented, then adaptability to slope angles is improved, but the adjustment becomes difficult to control and prone to over-adjustment
Solution Approach 1:
The holder incorporates a ratchet mechanism that provides tactile feedback and mechanical stops at predetermined adjustment positions. As the user adjusts the holder length, the ratchet engages at specific intervals to indicate proper positioning, preventing over-adjustment and making the adjustment process intuitive and controlled.
Solution Approach 2:
The ratchet mechanism预先 (in advance) prevents over-adjustment by providing mechanical resistance before the desired position is exceeded. This preliminary anti-action ensures that the holder cannot be adjusted beyond predetermined limits, eliminating the risk of over-adjustment before it occurs.
3Length of moving object
If the vane holder length is increased to accommodate steeper slopes, then the rotation space for the vane is improved, but light leakage occurs when the blind is closed
Solution Approach 1:
The telescopic holder allows dynamic adjustment of length to match the precise requirements of each slope angle. This eliminates the need to use excessively long holders for all applications, enabling the selection of the minimum necessary length that provides adequate rotation space without creating light leakage gaps.
Solution Approach 2:
By changing the length parameter of the holder through telescopic adjustment, the system optimizes the balance between providing sufficient rotation space and maintaining proper alignment to prevent light leakage. The length parameter is precisely controlled to match installation conditions.
4Adaptability or versatility
If a ratchet-type adjustment mechanism is used, then length adjustment is enabled, but the mechanism is difficult to control and requires excessive force
Solution Approach 1:
The patent replaces the traditional ratchet mechanism with a threaded spindle and nut system. This substitution transforms the adjustment mechanism from one requiring forceful engagement to one that provides smooth, controlled movement through rotational motion, significantly reducing the force needed for adjustment.
Solution Approach 2:
The threaded spindle acts as an intermediary that converts rotational motion into precise linear displacement. This mechanical transformation allows for fine control of the holder length with minimal input force, as the threading mechanism multiplies the effect of small rotational movements into precise positional changes.
