Solution Overview

Problem

Infrared thermometers face challenges in accurately aligning the sensing area due to errors in laser beam emission, making it difficult for users to identify the correct sensing region, leading to incorrect temperature readings.

Innovation Solution

A laser adjustment device and system that includes a first and second adjustment seat with pivot portions and elastic members, along with an electronic device for precise adjustment of the laser module, allowing the laser beam to be quickly and accurately aligned with the sensing area by measuring distances between the sensing-area image and the laser spot.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If laser modules are used to indicate the sensing area center, then the device cost is reduced compared to high-price infrared thermometers with sights, but the laser beam emission precision deteriorates with a error range of plus or minus 5 degrees

Engineering Contradiction:
Improvedevice costVSAvoidlaser beam emission precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies the dynamics principle by making the laser module adjustable rather than fixed. The laser module can be dynamically positioned in multiple directions (upward, downward, leftward, rightward) through adjustment mechanisms, allowing it to adapt to different sensing area positions. This resolves the contradiction by enabling precise alignment (improving manufacturing precision) while maintaining the cost-effectiveness of using a laser module instead of expensive sights.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If the sensing area is made larger to improve measurement coverage, then the measurement capability is enhanced, but the difficulty of detecting and measuring the sensing area position increases because the naked eye cannot pinpoint it

Engineering Contradiction:
Improvesensing areaVSAvoidsensing area position detection
Core Design Contradiction:
Area of stationary objectVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies the color changes principle by using a visible laser beam to create a distinct visual marker (laser light point) that indicates the sensing area center. The laser beam provides a bright, concentrated visual signal that contrasts with the surrounding environment, making it easy for users to identify the sensing region position. This resolves the contradiction by maintaining a large sensing area while solving the detection difficulty through optical visualization.

Inventive Principle:
Principle #32Color changes

3Manufacturing precision

If the laser adjustment device includes multiple adjustment portions and pivot portions for precise positioning, then the laser beam alignment precision is improved, but the device complexity increases

Engineering Contradiction:
Improvelaser beam alignment precisionVSAvoidadjustment device structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies the segmentation principle by dividing the adjustment device into multiple independent adjustment portions (first adjustment portion, second adjustment portion, third adjustment portion, fourth adjustment portion), each responsible for a specific adjustment function. Each portion can be adjusted independently through its own adjustment member, allowing precise control of the laser module position in different directions. This segmentation enables high alignment precision while keeping each individual adjustment mechanism relatively simple and manageable.

Inventive Principle:
Principle #1Segmentation
