Law Enforcement Video Holster with NFC Authentication and Tactile Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording devices for law enforcement require users to operate mechanical buttons, which can distract and increase risk during critical situations, and lack authentication to ensure the correct user is in possession of the device.
Innovation Solution
A holster with tactile control holes on the back for thumb operation and a Near Field Communications (NFC) chip for authentication, allowing users to control the device without exposing mechanical buttons and ensuring the device is securely associated with the intended user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical buttons are exposed on the front of the device for easy operation, then ease of operation is improved, but the risk of accidental operation by citizens and distraction from the user increases
Solution Approach 1:
The patent removes the mechanical buttons from the front surface of the device and places them on the back surface. This extraction of the harmful element (buttons from front view) eliminates the risk of citizens accidentally pressing buttons while maintaining operational accessibility for the wearer through the holster's control holes.
Solution Approach 2:
The holster acts as an intermediary between the device controls and the user. The control holes in the holster provide a tactile interface that transmits finger pressure to the buttons on the device back without exposing the buttons to the front, thus mediating the interaction to eliminate accidental activation while preserving ease of operation.
2Object-affected harmful factors
If mechanical buttons are placed on the back of the device to prevent citizen operation, then risk of accidental operation is reduced, but ease of operation deteriorates as users must remove the device to control it
Solution Approach 1:
The holster serves as a mediating structure that allows the user to operate buttons on the device back without removing the device. The control holes in the holster transmit tactile input from the user's fingers to the buttons, eliminating the need to remove the device while maintaining secure placement.
Solution Approach 2:
The system is segmented into three functional layers: the holster (interface layer), the device (processing layer), and the buttons (control layer). This segmentation allows independent optimization where the holster provides the user interface while the device remains secured, separating the operation function from the security function.
3Loss of information
If additional status query buttons are added to the device, then information availability is improved, but device complexity and ease of operation deteriorate due to complicated button sequences
Solution Approach 1:
The device automatically provides status information through the holster's LED light guide system without requiring additional buttons or complex user input. The system self-communicates battery status, recording time, and other information through light patterns visible through the holster, eliminating the need for extra control elements.
Solution Approach 2:
The patent replaces mechanical button-based status query interfaces with an optical communication system using LED lights visible through the holster. This substitution eliminates the need for additional mechanical buttons and complicated press sequences, providing information through visual cues that are inherently simpler to interpret.
4Reliability
If the device is made more secure through authentication mechanisms, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical authentication mechanisms (such as physical keys or multiple button sequences) with a simple NFC-based electronic authentication system. The NFC chips in the holster and device enable automatic identification and authentication through close proximity contact, significantly reducing the complexity of securing the device while maintaining high reliability.

AI summary
A video recording device and holster are disclosed to reliably and covertly start and stop capture of video, audio, and metadata, and perform other commands. The holster may include a plurality of holes through which defined commands can be executed using a touch-screen interface or other control devices. In one embodiment, the holster may be confirmed as being associated with the video recording device to authenticate a user. Moreover, the video recording device may enter a mode of operation associated with using the video recording apparatus automatically when inserted into a holster.
