Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing red dot sighting devices face issues with low precision, efficiency, and reliability in adjusting the LED chip's emitting direction due to spring interference and component complexity.
Innovation Solution
The LED mounting base features a sliding block base and a pedestal with a position locking mechanism, including a sliding slot and a spiral restoring spring, which allows precise adjustment of the LED chip's position without skewing, enhancing precision and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If vertical or horizontal adjusting screws are used for position adjustment, then the LED chip position can be adjusted, but spring interference causes mounting base skew resulting in lower precision and efficiency
Solution Approach 1:
The patent removes the restoring spring from the adjustment mechanism, extracting the harmful element that caused mounting base skew. The original design had a restoring spring that interfered with the adjusting screws, causing the mounting base to skew during adjustment. By eliminating the spring entirely, the patent resolves the interference problem and achieves reliable, precise adjustment without skewing.
Solution Approach 2:
The patent divides the adjustment mechanism into independent components: the adjusting screws for position control and the mounting base for securing the LED chip. By segmenting the mechanism and removing the coupling spring that caused interference, each component can function independently without causing skewing, thereby improving both precision and reliability.
2Adaptability or versatility
If a position adjusting assembly composed of multiple components is used, then the LED chip position can be adjusted in vertical and horizontal directions, but the complexity increases and spring interference reduces efficiency
Solution Approach 1:
The patent extracts and removes the restoring spring from the multi-component adjustment assembly, reducing the number of components and eliminating the complexity associated with spring installation, adjustment, and interference. This simplification maintains the position adjustment capability while reducing device complexity.
Solution Approach 2:
The patent merges the position adjustment function directly into the mounting base structure, eliminating the need for separate restoring spring components. The adjusting screws work directly on the mounting base without intermediate spring elements, combining functions and reducing overall component count and complexity.
3Ease of operation
If adjusting screws are used for single-direction adjustment, then the LED chip position can be modified, but mounting base skew occurs resulting in lower efficiency
Solution Approach 1:
The patent removes the restoring spring that caused mounting base skew during single-direction adjustment. By extracting this harmful element, the adjusting screws can operate smoothly in one direction without causing skew, thereby improving adjustment efficiency while maintaining ease of operation.

Implementation Method 1
A spiral restoring spring is disposed between one end of the above described pedestal and the blind end
Implementation Method 2
a steel ball with a radius larger than an inner diameter of a front end outlet of the hollow clamping cap, all of which are sequentially mounted in the blind hole from an inside to an outside; under the action of the spiral spring, the steel ball is touched against the front end outlet of the hollow clamping cap

AI summary
An LED mounting base, an adjustment mechanism with the LED mounting base and a red dot sighting device with the adjustment mechanism are provided in the present disclosure. The LED mounting base includes a sliding block base and a pedestal in which an LED chip is mounted at the middle of the front end surface thereof. A sliding slot parallel to the length direction of the pedestal is disposed on the front end surface of the sliding block base. One end of the sliding slot is a blind end, and the other end of the sliding slot is an open end. After the pedestal being disposed in the sliding slot, the front end surface of the pedestal is parallel to the front end surface of the sliding block base.
