Damper Plate Adjustment Slide With Dual-Thread Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment and locking means for ventilation devices are too large in diameter to fit through nozzle diffusers, making on-site adjustments difficult, and lack precise control across the entire adjustment range, especially near the closing position where air flow changes are most significant.
Innovation Solution
The adjustment and locking means feature threads on the outer rim of the regulator slide, with an unbroken thread for precise adjustments near the closing position and a partial thread for quick adjustments further away, allowing the regulator slide to move longitudinally and rotate for locking, enabling accurate control across the entire range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the adjustment and locking means is made large in diameter, then the adjustment accuracy is improved, but the device cannot fit through the nozzle diffuser for on-site adjustment
Solution Approach 1:
The thread structure is segmented into two distinct parts: a first thread extending along a first part of the outer rim for precise adjustments, and a second thread extending along a second part of the outer rim for quick adjustments. This segmentation allows the device to provide different adjustment characteristics in different regions without increasing overall diameter.
Solution Approach 2:
Different regions of the regulator slide are given different thread characteristics tailored to their specific functional requirements. The first thread provides fine adjustment capability where precision is critical, while the second thread enables rapid adjustment where speed is more important, optimizing the local quality of each region.
2Device complexity
If the same thread structure is used for the entire adjustment range, then the device structure is simplified, but the adjustment precision varies significantly across different positions
Solution Approach 1:
The adjustment mechanism is divided into two functional zones with different thread configurations. The first thread provides consistent precision for critical adjustments, while the second thread enables rapid positioning for less critical adjustments, ensuring precision consistency where needed without excessive complexity.
Solution Approach 2:
Each region of the regulator slide is equipped with thread characteristics optimized for its specific adjustment requirements, ensuring that precision is maintained where critical while allowing for simpler, faster adjustments in other regions.
3Length of moving object
If the adjustment and locking means is made compact, then it fits through the nozzle diffuser, but the adjustment range and locking capability are reduced
Solution Approach 1:
The compact regulator slide incorporates segmented threads that provide both fine adjustment capability and quick adjustment capability within a limited space, maintaining full adjustment range and locking capability despite the reduced diameter.
Solution Approach 2:
The dual-thread design utilizes the circumferential dimension of the regulator slide to provide multiple adjustment modes, effectively increasing functional capacity without increasing the overall diameter, allowing the device to fit through the nozzle diffuser while maintaining versatility.
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
This design allows for precise adjustments near the closing position while enabling quick and accurate locking further away, facilitating easier on-site adjustments and improved control over air flow, reducing the need for frequent opening and closing of the front plate.
Implementation Method 1
A cable or wire, which is mostly inside the shell and movable in its longitudinal direction, is fastened to the adjustment and locking means
Implementation Method 2
threads are arranged on the outer rim of the regulator slide, of which the first thread is unbroken and the second thread extends to a part of the outer rim of the regulator slide
Implementation Method 3
the adjustment can be made by pushing or pulling the regulator slide in relation to the handle part and the adjustment can be locked by rotating the regulator slide in relation to the handle part
