Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In safety applications, such as emergency stop command devices, the secure connection between the actuator and switching elements is crucial to ensure proper functioning, but inadequate assembly or excessive force can cause mechanical separation, rendering the device non-functional, which can lead to safety hazards.
Innovation Solution
A combination of actuator and holding device with a design that includes L-shaped transmission elements with a spring mechanism and a clamping ring, allowing for reliable transmission of switch position changes to multiple switching elements, ensuring a secure and stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If switching elements are mechanically connected to the actuator using screws, snap hooks or bolts, then the connection can be established, but the connection may become mechanically separated due to inadequate assembly or use of force
Solution Approach 1:
The holding device is divided into a first housing section for the actuator and a second housing section for the switching elements, connected via a guide rail system that allows modular assembly while maintaining secure connection
Solution Approach 2:
Transmission elements with L-shaped design and guide rails act as intermediaries between the actuator and switching elements, transmitting actuation forces reliably while preventing direct mechanical separation
2Speed
If plungers in the actuator directly control switching elements, then the response is direct, but the actuator requires larger size to accommodate all plungers
Solution Approach 1:
The patent uses L-shaped transmission elements that extend in multiple dimensions, allowing compact plunger design while maintaining direct actuation capability through spatial optimization
Solution Approach 2:
Transmission elements are nested within the holding device structure, with L-shaped configurations that allow plungers to control multiple switching elements through compact, space-efficient pathways
3Adaptability or versatility
If multiple switching elements are controlled via the actuator, then the device functionality is enhanced, but the connection reliability may be compromised due to increased complexity
Solution Approach 1:
The holding device with guide rails and transmission elements serves multiple functions: securing the actuator, guiding transmission elements, and controlling multiple switching elements through a unified reliable connection system
Solution Approach 2:
The patent combines the actuator housing, transmission element guidance, and switching element mounting into an integrated holding device structure, ensuring unified connection reliability across all components
