Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adjusting the detection range of motion sensors are time-consuming and labor-intensive, requiring multiple adjustments and tests to set a suitable threshold, especially in large systems with multiple detectors.
Innovation Solution
A portable control device with communication, display, and input means allows direct adjustment of the detection threshold by displaying the detection signal generated by the operator's movement within the sensor's range, enabling easy and reliable setting of the threshold without trial and error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection threshold is adjusted by trial and error method, then the sensor range can be set, but the adjustment process becomes extremely time-consuming
Solution Approach 1:
The patent implements a feedback mechanism where the motion sensor continuously provides detection signals to the portable control device, which displays real-time feedback to the user. This allows the user to see the immediate effect of threshold adjustments without trial-and-error physical testing, directly resolving the time-consuming adjustment process while maintaining accuracy.
Solution Approach 2:
The portable control device serves as an intermediary between the user and the motion sensor. It receives detection signals from the sensor, processes the threshold adjustment commands from the user, and transmits the adjusted thresholds back to the sensor. This intermediary eliminates the need for direct trial-and-error testing by the user and automates the adjustment process.
2Adaptability or versatility
If the detection threshold is adjusted manually on the sensor, then the range can be modified, but the process requires climbing to the sensor location which is usually near the ceiling
Solution Approach 1:
The portable control device acts as a remote intermediary that allows users to adjust the detection threshold from ground level without physically accessing the ceiling-mounted sensor. The control device communicates wirelessly with the sensor, transmitting threshold adjustment commands and receiving detection signals, thereby making the adjustment process accessible and safe.
Solution Approach 2:
The patent replaces the mechanical approach of physically accessing the sensor (climbing to ceiling location) with a wireless electronic system. The portable control device uses wireless communication to remotely adjust the sensor's detection threshold, substituting mechanical access with electronic control and eliminating the need for physical proximity to the sensor.
3Device complexity
If the detection threshold is set without real-time feedback, then the adjustment process is simple, but it requires multiple adjustments and tests to achieve satisfactory results
Solution Approach 1:
The portable control device displays real-time detection signals received from the motion sensor, providing immediate feedback to the user about the current threshold effectiveness. This feedback loop allows users to make informed adjustments in a single pass rather than requiring multiple trial-and-error cycles, significantly improving setup efficiency while maintaining process simplicity.
Solution Approach 2:
The system performs preliminary detection and displays the detection signal before the user finalizes the threshold adjustment. This preliminary action allows the user to see the expected outcome of the adjustment beforehand, enabling more accurate threshold setting in a single attempt and reducing the need for repeated adjustments.

AI summary
The invention relates to a portable control apparatus (100) for controlling a motion sensor (200), comprising communication means (110), display means (120) and input means (130). The communication means (110) allow wireless communication with a motion sensor (200) and are suitable for receiving a detection signal, currently generated in the motion sensor (200), from the motion sensor (200) while the control apparatus (100) is in a detection region (210) of the motion sensor (200). The display means (120) allow this detection signal to be displayed. The input means (130) allow the adjustment of a detection threshold at which a movement is detected by the motion sensor (200), on the basis of the displayed detection signal. The adjusted detection threshold is transferred to the motion sensor (200) by the communication means (110) and set there as the applicable detection threshold.
