Detection Switch Fixture for Maintenance Actuator Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During maintenance work inside a door with a mounted detection switch, the detection accuracy of the switch decreases due to the presence of a maintenance-use actuator, leading to difficulties in smooth maintenance progress.
Innovation Solution
A fixture is designed to mount a maintenance-use actuator to the sensor main body of the detection switch, maintaining a predetermined distance and preventing erroneous detection by using a holding portion, mounted portions, and a protrusion to ensure accurate communication between the actuator and the sensor main body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a maintenance-use actuator is prepared in addition to the actuator provided in the door, then maintenance work can be performed, but the detection accuracy of the detection switch decreases
Solution Approach 1:
The solution segments the actuator system into two distinct parts: a door-mounted actuator for normal operation and a maintenance-use actuator mounted on the fixture. By physically separating these actuators and assigning them different functions, the system maintains detection accuracy for door status while enabling maintenance capabilities through the separate maintenance actuator that can be positioned as needed.
2Productivity
If a maintenance-use actuator is mounted to the sensor main body, then maintenance work can be performed smoothly, but the structure becomes more complex
Solution Approach 1:
The fixture is designed as a multi-functional device that serves multiple purposes: it provides a mounting platform for the maintenance-use actuator, includes a protrusion to prevent door interference, and can be detachably mounted to the sensor main body. This universal design consolidates multiple maintenance and protective functions into a single integrated component, reducing overall system complexity despite the added capabilities.
3Reliability
If the maintenance-use actuator is positioned close to the sensor main body, then communication is ensured, but the normal actuator may enter the detection range causing erroneous detection
Solution Approach 1:
The protrusion on the fixture acts as a physical intermediary that creates a controlled barrier between the door-mounted actuator and the sensor main body. This intermediary structure ensures that the maintenance-use actuator remains within communication range of the sensor while preventing the door-mounted actuator from entering the detection range, thereby eliminating erroneous detection while maintaining reliable communication.

AI summary
A fixture for mounting a maintenance-use actuator to a sensor main body of a detection switch includes a holding portion configured to hold the actuator that communicates with the sensor main body when a distance to the sensor main body is within a predetermined distance, a mounted portion detachably mounted to the sensor main body in a manner of maintaining the distance between the actuator held by the holding portion and the sensor main body within the predetermined distance, a main body frame connecting the holding portion and the mounted portion and extending along a first direction, and a protrusion protruding and extending from the main body frame along a third direction perpendicular to the first direction and a second direction from the fixture toward the sensor main body in a mounted state where the fixture is mounted to the sensor main body.
