Object Detection Device Battery Replacement Without Optical Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object detection systems require optical adjustment and detection area adjustment every time the battery is replaced, which is time-consuming and costly, especially when using active infrared (AIR) type sensors, as the sensor body needs to be removed and reinstalled, necessitating two workers for alignment.
Innovation Solution
A battery-powered object detection device with a storage enclosure that allows battery replacement without removing the sensor body from the mounting plate, featuring a holding portion opening unit that enables battery replacement without optical or detection area adjustments, using a battery covering to prevent unauthorized access and a tamper switch for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the sensor body is removed for battery replacement, then the battery can be replaced, but optical adjustment is required again which increases time and labor cost
Solution Approach 1:
The device is divided into separate functional modules: the sensor body housing and the battery compartment. The battery compartment can be opened and accessed independently without removing the sensor body from the mounting plate. This segmentation allows battery replacement to occur without disturbing the optically aligned sensor body, thereby eliminating the need for repeated optical adjustments.
2Ease of operation
If the sensor body is removed and reinstalled, then battery replacement is possible, but alignment between beam projector and beam receiver must be re-established requiring two workers
Solution Approach 1:
The battery compartment is segmented as a separate accessible module that can be opened independently. This allows battery replacement without moving the sensor body, thereby avoiding the complex alignment procedure that would otherwise require two workers to re-align the beam projector and beam receiver.
3Ease of repair
If the object detection device is removed from mounting plate for battery replacement, then battery can be accessed, but device must be remounted and detection area adjusted
Solution Approach 1:
The battery compartment is designed as a separately accessible segment that can be opened and accessed without removing the entire object detection device from the mounting plate. This segmentation enables battery replacement to be performed quickly in-place, maintaining high installation efficiency and eliminating the need for detection area adjustment.
4Reliability
If a secure battery compartment is provided, then unauthorized access is prevented, but battery replacement may become more difficult
Solution Approach 1:
The battery compartment incorporates a tamper switch that automatically detects when the compartment is opened and triggers an alarm or security response. This self-service security mechanism prevents unauthorized access while allowing authorized users to easily replace batteries by simply opening the compartment, which then automatically resets the security system.

AI summary
To provide an object detection device that requires neither the optical adjustment nor the detection area adjustment after the replacement of the battery, the object detection device includes a sensor body, inclusive of a detection element, and a storage enclosure positioned in part or in its entirety in a rear surface of the sensor body, and has a transmitter accommodation portion for accommodating therein a transmitter for wirelessly transmitting an output signal from the sensor body, a battery holding portion for holding a battery for providing the sensor body and the transmitter with an electric power, in which the battery holding portion includes a holding portion opening unit to open the battery holding portion to thereby enable a replacement of the battery, then retained in the battery holding portion, in a condition in which the sensor body is not separated from the storage enclosure.
