Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional mounting bracket is used for the optical sensor, then the sensor can be securely attached to the equipment, but the bracket requires a relatively large installation space and can only be mounted in a specific orientation
Solution Approach 1:
The mounting bracket is divided into two separate mounting planes with independent fastening means, allowing the sensor to be mounted in different orientations without requiring a large installation space. The first mounting plane provides stable attachment while the second mounting plane enables orientation adjustment.
Solution Approach 2:
The invention transitions from a single-plane mounting system to a multi-plane mounting system. By adding a second mounting plane with different fastening means, the system gains freedom in orientation selection without increasing the footprint area of the bracket.
2Adaptability or versatility
If a complex mounting bracket design is used to provide multiple mounting options, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The bracket is segmented into two distinct mounting planes, each with its own fastening means. This segmentation provides mounting position flexibility while keeping each plane's structure relatively simple and manageable.
Solution Approach 2:
The mounting bracket is designed with multi-functionality by incorporating two mounting planes that can accommodate different mounting scenarios. This universal design allows the same bracket to serve multiple mounting purposes without requiring multiple different bracket designs.
3Reliability
If the light-emitting surface is exposed without protection, then the light beams can be transmitted efficiently, but dust and moisture can interfere with the light path and reduce reliability
Solution Approach 1:
A transparent cover plate is introduced as an intermediary element between the light-emitting surface and the external environment. This cover plate protects the light path from dust and moisture while maintaining optical transparency, thus preventing harmful factors from interfering with light transmission.
4Object-affected harmful factors
If a transparent cover plate is added to protect the light-emitting surface, then protection against dust and moisture is improved, but the device complexity increases
Solution Approach 1:
The transparent cover plate is merged with the mounting bracket structure, forming an integrated protective enclosure. This combining approach provides dust and moisture protection while avoiding the need for separate protective components, thus not significantly increasing device complexity.
Applied Scientific Principles
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 solution enables flexible installation options, enhanced protection of the optical sensor, and improved reliability by preventing crosstalk between transmitted and received light beams, thus enhancing the sensor's functionality and adaptability in various industrial settings.
Implementation Method 1
The mount has a transparent cover plate which, when the optical sensor is mounted in the mount, lies in front of the light-emitting surface
Implementation Method 2
The optical sensor has sensor components arranged in a housing, which emit and/or receive light beams, wherein a front wall of the housing forms a light-emitting surface through which the light beams are guided
