Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dot sight devices for firearms, such as pistols, are cumbersome and increase the overall size of the pistol, making them difficult to carry and store, and they can be affected by external vibrations during aiming.
Innovation Solution
A foldable dot sight device with a rotatable aiming unit and protective cover that can be easily unfolded and locked in place, preventing arbitrary movement during use and allowing for compact storage and carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional dot sight device is attached to a pistol, then aiming accuracy is improved, but the overall size of the pistol increases significantly
Solution Approach 1:
The patent applies the dynamics principle by making the dot sight device foldable. The aiming unit can be rotated between a folded state (aligned with the barrel axis) and an unfolded state (perpendicular to the barrel axis). This dynamic configuration allows the pistol to maintain compact size during carrying and storage while providing full aiming functionality when needed, directly resolving the contradiction between aiming accuracy and overall size.
2Measurement precision
If a conventional dot sight device is attached to a pistol, then aiming accuracy is improved, but portability and storage convenience deteriorate
Solution Approach 1:
The foldable design with rotatable aiming unit enables the pistol to transition between compact and functional states. When folded, the pistol maintains a streamlined profile for easy carrying and storage. When unfolded, the full dot sight functionality is available for accurate aiming, thus improving both portability and maintaining aiming accuracy.
Solution Approach 2:
The dot sight device is segmented into a body and a separately rotatable aiming unit. This segmentation allows the aiming unit to be folded against the barrel during storage and unfolded during use, providing portability benefits while maintaining full aiming capability when needed.
3Reliability
If the protective cover is connected to the aiming unit, then protection is provided, but the aiming unit may move arbitrarily due to external forces
Solution Approach 1:
The patent extracts the protective cover from the aiming unit, making them separate components. The protective cover is attached to the body and can rotate independently, while the aiming unit rotates on its own axis. This separation ensures that external forces applied to the protective cover during firing do not transmit to the aiming unit, preventing arbitrary movement and maintaining aiming stability while still providing protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The foldable design enhances portability and storage convenience while maintaining aiming accuracy by preventing the aiming unit from moving due to external forces, allowing quick target acquisition and improved handling of the pistol.
Implementation Method 1
a reflective mirror that transmits the image of the target in front toward the shooter and reflects the dot provided from the dot generator toward the shooter

AI summary
A foldable dot sight device is provided that includes a body capable of being assembled into a firearm. A dot generator is disposed on the body, and is capable of generating a dot for aiming at a target. A reflective mirror is provided, which transmits an image of a target toward the user and reflects the dot generated by the dot generator. A housing is connected to the reflective mirror. A protective cover includes a sliding guide rotatably connected to the body and rotates the housing in a folding or unfolding direction according to a rotational position.
