Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser-aiming devices for radiant thermometers are complex, costly, and difficult to calibrate, leading to inaccurate indication of the detectable area, resulting in incorrect temperature measurements.
Innovation Solution
A simple-structure laser-aiming device comprising a laser adjustment seat, a laser device, and a prism with two inclined faces that refracts a single laser beam into two spots to clearly indicate the detectable area, featuring adjustable mechanisms for easy calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single laser beam is used to indicate the center of the detectable area, then the structure is simple and cost is low, but the detectable area cannot be accurately indicated
Solution Approach 1:
The patent divides the single laser beam into two separate laser beams by introducing a beam splitter (45-degree semitransparent mirror). These two beams then form two distinct laser spots that mark the boundaries of the detectable area, allowing accurate indication of the measurement zone while maintaining relatively simple device structure
Solution Approach 2:
The patent introduces a beam splitter (45-degree semitransparent mirror) as an intermediary component between the laser device and the detectable area. This mediator redirects and splits the laser beam to create two separate spots, enabling accurate boundary indication without requiring complex adjustment mechanisms
2Measurement precision
If a 45-degree semitransparent mirror and adjustment device are used to split the laser beam, then the detectable area can be indicated, but the overall architecture becomes complex
Solution Approach 1:
The patent extracts and eliminates the complicated adjustment device from the system. By using a fixed 45-degree semitransparent mirror that inherently splits the beam at the correct angle, the design achieves accurate detectable area indication without requiring complex adjustment mechanisms, thereby simplifying the overall architecture
3Ease of operation
If a diffraction element is arranged before the laser device to deflect the laser light, then the laser beam can be directed, but the output laser light is not necessarily coaxial with the housing and may not project on the correct position
Solution Approach 1:
The patent uses a 45-degree semitransparent mirror as an intermediary component that reliably splits the laser beam into two beams at the correct angle. This mediator ensures that the output laser lights are coaxial with the housing and project on the correct positions, avoiding the positioning errors associated with diffraction elements
