Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio wave sensor installation methods struggle to quickly and accurately adjust the direction of radio wave sensors to detect larger areas, such as those required for vehicle detection, due to limited visual recognition through traditional sighting devices.
Innovation Solution
The use of a sighting device with transparent members featuring distinct sighting marks, allowing workers to align and adjust the radio wave sensor direction more accurately and efficiently by visualizing a larger region around the reference point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional sighting devices with limited visual recognition are used, then the device complexity is reduced, but the manufacturing precision of radio wave sensor direction adjustment deteriorates
Solution Approach 1:
The sighting device is divided into multiple transparent members (first transparent member and second transparent member), each containing distinct sighting marks. This segmentation allows workers to align multiple marks simultaneously, improving direction adjustment accuracy while keeping each individual transparent member relatively simple in structure.
Solution Approach 2:
The invention transitions from a single-plane sighting mark to a multi-plane arrangement with sighting marks on different transparent members. By adding the dimension of multiple overlapping transparent members, the system enables more precise spatial alignment and direction verification without significantly increasing overall device complexity.
2Productivity
If traditional sighting devices are used, then the device complexity is reduced, but the productivity of sensor installation deteriorates
Solution Approach 1:
The transparent members are pre-marked with sighting marks (graph-paper patterns or concentric-circle patterns) during manufacturing. This preliminary action allows workers to quickly align the marks during installation without needing to create alignment references on-site, thereby improving installation speed while the marks are already integrated into the device structure.
Solution Approach 2:
The sighting marks are designed with distinct visual characteristics (graph-paper patterns or concentric-circle patterns) that provide high visual contrast and ease of recognition. This visual differentiation enables workers to quickly identify and align the marks, improving installation productivity without adding mechanical complexity to the device.
3Measurement precision
If traditional sighting devices are used, then the device complexity is reduced, but the measurement precision of direction alignment deteriorates
Solution Approach 1:
The alignment measurement is segmented into multiple reference points (first sighting mark on first transparent member, second sighting mark on second transparent member). By requiring simultaneous alignment of multiple segmented reference points, the system achieves higher measurement precision for direction alignment while each individual mark remains simple in structure.
Solution Approach 2:
The alignment verification is extended from a single-plane mark to a multi-layer arrangement of transparent members with sighting marks. This dimensional extension provides multiple reference planes for alignment verification, improving measurement precision without significantly increasing the complexity of each individual transparent member.

AI summary
A radio wave sensor installation method has the following steps. A sighting device is mounted onto a radio wave sensor. The direction of the radio wave sensor is adjusted using the sighting device. The direction of the radio wave sensor is fixed. The sighting device is removed from the radio wave sensor. The sighting device includes a first transparent member and a second transparent member different from the first transparent member. In the step of adjusting the direction of the radio wave sensor using the sighting device, the direction of the radio wave sensor is adjusted using a first sighting mark indicated on the first transparent member and a second sighting mark indicated on the second transparent member.
