Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photoelectric sensors in production facilities face challenges in space-saving due to the need for cable routing on the bottom surface, leading to wasted space and inefficient placement.
Innovation Solution
The photoelectric sensor design features a cable attached to the rear surface, eliminating the need for bottom surface routing and allowing for a more compact form factor by utilizing the rear surface space, with attachment sections and a cable protection member to enhance durability and reduce noise interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cable is connected to the bottom surface of the case body, then the cable routing is simple, but the placement space is wasted
Solution Approach 1:
The cable connection position is changed from the bottom surface (horizontal plane) to the rear surface (vertical plane), utilizing a different spatial dimension. This allows the cable to be routed vertically along the rear surface rather than horizontally along the bottom surface, eliminating the need for additional placement space while maintaining routing simplicity.
2Reliability
If the cable is connected to the bottom surface of the case body, then the connection is stable, but the sensor size increases
Solution Approach 1:
By moving the cable connection to the rear surface, the patent utilizes the vertical dimension of the case body rather than extending the horizontal dimension. This allows the sensor to maintain a compact footprint while providing a stable connection point that can accommodate cable routing without increasing the overall sensor volume.
3Area of stationary object
If the cable is connected to the rear surface of the case body, then the placement space is saved, but the cable routing becomes more complex
Solution Approach 1:
The patent provides a specific cable connection structure on the rear surface with dedicated cable passing holes and routing paths. This localized design concentrates the cable routing functionality in a specific area, making the routing process straightforward despite the changed connection position, and actually simplifying the overall cable management compared to alternative configurations.
4Volume of moving object
If the cable is connected to the rear surface of the case body, then the sensor size is reduced, but the cable protection becomes more difficult
Solution Approach 1:
The patent incorporates a cable protection structure integrated into the rear surface connection assembly, providing localized protection at the critical cable entry point. This includes features such as cable clamps, grommets, or protective channels that safeguard the cable where it enters the case body, maintaining protection effectiveness while keeping the overall sensor size compact.
