Filling Module Screen Blocks Infrared Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adjacent arrangement of two receptacles on a vehicle for fuel gas filling can cause interference due to the wide range of infrared rays transmitted, leading to inefficient fuel gas filling operations.
Innovation Solution
A filling module with a screen portion projecting towards the gas station between the transmitters on the receptacles, ensuring that the infrared rays do not interfere with each other's receivers, allowing for adjacent placement of the receptacles without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two receptacles are arranged adjacent to each other for simultaneous filling, then filling speed is improved, but infrared ray interference occurs between the transmitters and receivers
Solution Approach 1:
A screen portion is introduced as an intermediary element between the first transmitter and second receiver, and between the second transmitter and first receiver. This screen portion blocks the infrared rays transmitted by one transmitter from reaching the other receiver, thereby preventing interference while allowing both receptacles to be arranged adjacently for simultaneous filling operations.
Solution Approach 2:
The problem of infrared ray interference in the horizontal plane is resolved by introducing a vertical dimension. The screen portion extends in the vertical direction (height direction) to block infrared rays, transforming the interference prevention approach from horizontal separation to vertical shielding, thereby enabling adjacent horizontal arrangement of receptacles.
2Volume of moving object
If two receptacles are arranged adjacent to each other for downsizing the vehicle, then vehicle size is reduced, but infrared ray interference occurs
Solution Approach 1:
The screen portion serves as a mediating structure that enables close spacing of receptacles by blocking infrared interference. This allows the vehicle to maintain a compact size with adjacent receptacle arrangement while preventing the infrared ray interference that would otherwise occur in such close proximity.
Solution Approach 2:
The screen portion is divided into multiple sections (first screen portion and second screen portion) that can be independently positioned between the respective transmitter-receiver pairs. This segmentation allows precise placement of shielding elements to block interference paths while minimizing impact on vehicle space utilization.
