RVDT Shaft Connector With Adjustable Angular Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for RVDT and reductor shaft connections lack the ability to conveniently adjust the angular position of the RVDT, which is essential for aligning the 0° position after maintenance or changes in the system.
Innovation Solution
A connector with a body defining a bore for the reductor shaft and a threaded tightening member, allowing the connector to deform and grip the reductor shaft, enabling easy adjustment of the RVDT's angular position by loosening and re-tightening the tightening member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional rigid connector is used to connect the RVDT and reductor shaft, then the connection is stable and secure, but the angular position of the RVDT cannot be adjusted conveniently
Solution Approach 1:
The connector body is designed with a deformable portion that can change its grip on the reductor shaft. The threaded tightening member allows the connector to transition between a loose state (for adjustment) and a tightened state (for secure connection). This dynamic capability enables both adjustability and stability.
Solution Approach 2:
The connector utilizes changes in the physical state of the deformable portion through tightening. As the threaded tightening member is rotated, it applies force that deforms the deformable portion, changing its shape and grip characteristics. This parameter change allows the connector to transition from an adjustable state to a locked state.
2Ease of operation
If the threaded tightening member is positioned perpendicular to the bore axis, then the connector structure is compact, but the tightening member is difficult to access for adjustment
Solution Approach 1:
The threaded tightening member is repositioned from a perpendicular orientation to a parallel orientation relative to the bore axis. This dimensional repositioning places the tightening member on the end face of the connector body, making it accessible from the RVDT side without requiring access to the side of the connector.
3Strength
If the connector body is made completely rigid to ensure secure connection, then the connection strength is high, but the connector cannot deform to grip the reductor shaft
Solution Approach 1:
The connector body is divided into a rigid portion and a deformable portion. The rigid portion maintains overall structural integrity and connection strength, while the deformable portion can locally deform to grip the reductor shaft. This segmentation allows both strength and adaptability.
Solution Approach 2:
Only the specific deformable portion of the connector body is made flexible, while the rest of the connector remains rigid. This localized quality change allows the connector to maintain overall strength while having a specific region capable of deformation for gripping the shaft.

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 connector allows for convenient and secure adjustment of the RVDT's angular position relative to the reductor shaft, facilitating maintenance and ensuring accurate position alignment without damaging the reductor shaft.
Implementation Method 1
A threaded tightening member which is substantially parallel to a main axis of the bore. A portion of the body is configured to deform upon tightening of the tightening member such that, when the reductor shaft is received by the bore, the reductor shaft is gripped by at least a portion of the inner wall.

AI summary
A connector for adjustably connecting an RVDT (rotary variable differential transformer) and a reductor shaft. The connector includes a body defining a bore configured to receive the reductor shaft. The bore has an inner wall and a threaded tightening member which is substantially parallel to a main axis (AA, BB) of the bore. A portion of the body is configured to deform upon tightening of the tightening member such that, when the reductor shaft is received by the bore, the reductor shaft is gripped by at least a portion of the inner wall.
