Actuator Device Sensor Segmentation for Transmission Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing throttle valve control devices face limitations in selecting sensor size and transmission ratio due to structural constraints, leading to restricted angular position monitoring and increased assembly complexity.
Innovation Solution
The actuating device features a sensor with a stationary and movable part, where the sensor is partially housed within a cover unit, allowing for independent manufacturing and assembly, enabling a larger transmission ratio and protection against environmental influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor is integrated into the throttle valve body with a cover, then protection against environmental influences is achieved, but the selection of sensor size and transmission ratio is restricted
Solution Approach 1:
The device is divided into two separate assemblies: a throttle body assembly containing the throttle valve, shaft, and gear, and a cover assembly containing the sensor. This segmentation allows each assembly to be manufactured and optimized independently, enabling free selection of sensor size and transmission ratio without compromising protection against environmental influences.
Solution Approach 2:
The cover acts as an intermediary element that houses the sensor and connects to the throttle body assembly. By placing the sensor in the cover rather than directly in the throttle valve body, the patent enables independent sensor selection while maintaining environmental protection through the cover's protective function.
2Ease of manufacture
If a U-shaped circuit board with potentiometer tracks is used, then the cover can be attached to the throttle body, but the sensor selection is restricted
Solution Approach 1:
The sensor is extracted from the traditional integrated configuration and placed in the cover assembly. This extraction eliminates the constraint of using U-shaped circuit boards with potentiometer tracks, allowing selection from a broader range of sensor types and configurations while maintaining ease of assembly.
3Volume of moving object
If gear wheels are arranged in a compact configuration, then structural volume is reduced, but the transmission ratio selection is restricted
Solution Approach 1:
The gear transmission system is segmented into the throttle body assembly with its gear wheels and the separate cover assembly with the sensor. This segmentation allows the gear wheels to be arranged in a compact configuration within the throttle body while the sensor in the separate cover can be optimally sized and positioned, achieving both compact volume and flexible transmission ratio selection.

AI summary
The adjusting device (2) has a throttle body (4,4a) which is provided at a bearing element (14,14a) that is pivoted around a rotating axis (50) in the housing (10). A throttle body sided drive element (16,16a) is provided at the bearing element, where a part of a sensor (40,40.2,40.4), is arranged between the throttle body sided drive element and a circular diameter (36.1) of a sprocket (36). An independent claim is also included for a method for manufacturing an adjusting device.
