Innovation Solution
The development of compact green laser gun sights that allow for easy attachment to various handguns, featuring a housing that acts as a heat sink, enabling elevation and windage adjustments without moving the entire laser module, and automatic on/off functionality based on holster status, using a smaller laser module and efficient power management to conserve battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If green laser energy is used in sighting devices, then visibility is improved, but device size increases due to additional components
Solution Approach 1:
The patent combines the green laser module with the housing structure, where the housing serves multiple functions including structural support and heat dissipation. The frequency doubler crystal and other optical components are integrated within the compact housing, merging multiple functions into a single compact unit that maintains green laser visibility while reducing overall device size.
Solution Approach 2:
The housing is designed to perform multiple functions: providing structural support, dissipating heat from the laser module, and housing the optical components. This multi-functionality allows the device to maintain compact dimensions while supporting the additional components required for green laser operation.
2Illumination intensity
If green laser energy is used in sighting devices, then visibility is improved, but power consumption increases
Solution Approach 1:
The laser operation is controlled in periodic intervals rather than continuous operation. The system activates the green laser only when needed for targeting, reducing overall power consumption while maintaining visibility effectiveness during active use periods.
Solution Approach 2:
The system adjusts operational parameters including duty cycle and power levels to optimize the balance between visibility and power consumption. By varying these parameters based on operational needs, the device maintains effective green laser visibility while managing power consumption within acceptable limits.
3Illumination intensity
If green laser energy is used in sighting devices, then visibility is improved, but battery life decreases
Solution Approach 1:
The laser operates in periodic intervals with duty cycles that allow battery recharging between active periods. This periodic operation pattern maintains effective visibility during use while extending battery life by reducing continuous power draw.
Solution Approach 2:
The system maintains readiness for immediate laser activation while in standby mode, using low-power monitoring circuits that quickly transition to full power when needed. This approach ensures continuous operational capability while minimizing average power consumption to extend battery life.
4Ease of operation
If traditional mounting methods are used, then accessory attachment is achieved, but adaptability to different firearms is reduced
Solution Approach 1:
The device incorporates a universal mounting interface that can accommodate different firearm types and configurations. The mounting system is designed to work with various rail configurations and attachment points, providing broad firearm compatibility while maintaining ease of installation and removal.
Solution Approach 2:
The mounting system allows for dynamic adjustment and reconfiguration to suit different firearms. Components can be positioned and secured at various locations along the firearm barrel, enabling the same device to be adapted to multiple firearm platforms without requiring custom mounting solutions for each type.

AI summary
An electronic accessory for a firearm includes a housing including a right side, a left side, and an attachment mechanism for securing the electronic accessory to the firearm. The housing contains components of the electronic accessory. The components of the electronic accessory include an electronic component, a sensor sensing a magnetic field, and a circuit board coupled to the electronic component and the sensor. The circuit board controls the electronic component and suspends power to the electronic component when the sensor senses a magnetic field above a threshold strength. A first switch is disposed on the right side of the housing and a second switch is disposed on the left side of the housing. The switches are operable to control the electronic component via the circuit board. A power source provides power to at least one of the electronic component, the sensor, and the circuit board.
