Solution Overview
Problem
Existing red dot sights rely on LED point light sources that can only produce circular or oval light spots, leading to complex systems and operations, and are powered by batteries with limited lifetimes, increasing costs and requiring manual brightness adjustments. Additionally, dustproof covers are difficult to open quickly and installation card tracks are not efficient.
Innovation Solution
A red dot sight with an LED light source capable of projecting graphic logos using a combination of point and peripheral light sources, integrated with a solar cell for power, and a dustproof cover mechanism that allows 360° rotation and quick opening, along with an improved installation card track for enhanced operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED surface light sources are used to produce specific shaped light spots via raster interception, then light spot shape versatility is improved, but power consumption increases and system complexity increases
Solution Approach 1:
The patent extracts the shape-defining function from complex raster interception systems and implements it directly within the LED light source itself, eliminating the need for power-hungry raster mechanisms while maintaining shape versatility
Solution Approach 2:
The patent replaces mechanical raster interception systems with an optimized LED optical design that achieves the same shape-control function through lens or reflector geometry, reducing power consumption while maintaining versatility
2Ease of operation
If batteries are used to power red dot sights, then portable operation is enabled, but service lifetime is limited and replacement cost increases
Solution Approach 1:
The patent reduces power consumption parameters of the LED light source and associated electronics, extending battery service lifetime while maintaining portable operation capabilities
Solution Approach 2:
The patent implements brightness regulation through periodic dimming or pulsing of the LED output, reducing average power consumption and extending battery life while maintaining visibility when needed
3Adaptability or versatility
If manual brightness regulation switches are used to adjust output light brightness, then brightness adaptability to environment is improved, but operation complexity increases
Solution Approach 1:
The patent incorporates ambient light sensing with automatic feedback control to regulate LED brightness, eliminating manual switch operations while maintaining adaptability to environmental lighting conditions
Solution Approach 2:
The red dot sight performs self-regulation of brightness based on ambient conditions through integrated sensors and control circuitry, eliminating the need for manual user intervention
4Object-affected harmful factors
If dustproof covers are opened by manual manipulation of coupling pins, then dust protection is provided, but opening speed is slow and operation reliability decreases
Solution Approach 1:
The patent uses vibration or shock mechanisms to quickly release the coupling pin engagement, enabling rapid dustproof cover opening while maintaining secure closure when closed
Solution Approach 2:
The patent transitions the dustproof cover from static manual operation to dynamic quick-release mechanism that can be rapidly opened or closed with minimal user input
5Reliability
If lock catches are actuated by drawing to cam handle trigger portions, then installation card track locking is achieved, but operation requires large strength and proper angle reducing speed
Solution Approach 1:
The patent employs cam surfaces with optimized curvature profiles that convert small linear movements into effective locking actions, reducing the force and precision requirements for operation while maintaining reliable engagement
Solution Approach 2:
The patent uses a cam mechanism where excessive or partial actuation motion automatically ensures full engagement, eliminating the need for precise force direction or angle while maintaining locking reliability
