Air Purge Unit with Selective Mounting for Sensor Lens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation position of air purge units is typically fixed due to the fixed connection of air injectors, limiting the flexibility and versatility of their placement in environments where photoelectric sensors are used, such as machining settings where dirt accumulation is a concern.
Innovation Solution
The air purge unit design features multiple connection points for the air injector, allowing it to be selectively mounted on various surfaces (upper, lower, or rear) of the optical sensor, enhancing the degree of freedom in installation positions and enabling easy detachment and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air injector is fixedly connected to the air purge unit, then the connection is stable and reliable, but the installation position of the air purge unit is greatly limited
Solution Approach 1:
The air purge unit is divided into a main body and a detachable connection portion. The connection portion can be selectively attached to different positions (upper surface, lower surface, or rear surface) of the optical sensor, allowing the same air purge unit to be installed in multiple locations while maintaining a stable fixed connection when attached.
Solution Approach 2:
The connection between the air purge unit and the optical sensor is made changeable rather than fixed. The connection portion can be attached to different surfaces depending on the installation requirements, transforming the static installation into a dynamic, adaptable configuration.
2Device complexity
If the air purge unit is designed with fixed installation position, then the structure is simple, but the degree of freedom in installation position is limited
Solution Approach 1:
The air purge unit is designed with a universal connection portion that can be attached to multiple different positions (upper, lower, or rear surfaces) of the optical sensor. This single design serves multiple installation purposes, making the device multi-functional without significantly increasing structural complexity.
