Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the gas sensor uses conventional design emphasizing detection speed, then detection speed is improved, but measurement precision deteriorates under shock conditions
Solution Approach 1:
The patent applies beforehand cushioning by introducing a shockproof unit with buffer portions made of elastic material that is coupled between the gas detector and the circuit board. This elastic buffer absorbs shocks and vibrations before they can reach the infrared source and detector, preventing distortion and maintaining measurement precision while allowing the detection system to operate at high speeds.
2Stability of the object's composition
If the gas detector is rigidly secured to the circuit board, then structural stability is improved, but shock resistance deteriorates
Solution Approach 1:
The patent employs flexible shells and thin films by using an elastic buffer material in the shockproof unit that is coupled between the gas detector and the circuit board. This elastic material provides flexible connection that can deform under shock conditions, absorbing impact energy while maintaining the structural stability and alignment of the infrared source and detector during normal operation.
3Volume of moving object
If the infrared source and detector are positioned close to each other for compact design, then device compactness is improved, but shockproof performance deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the mounting structure into distinct functional components: the gas detector, the shockproof unit with buffer portions, and the circuit board. This segmentation allows the shockproof unit to be strategically positioned between the infrared source/detector assembly and the circuit board, providing shock absorption while maintaining compact overall device dimensions through optimized spatial arrangement.
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 solution effectively prevents the infrared detector and source from shifting or distorting upon shocks, ensuring stable infrared distribution and measurement precision by securely attaching the gas detector to the circuit board through shockproof units.
Implementation Method 1
The conventional carbon dioxide sensor or analyzer uses non-dispersive infrared (NDIR) absorption to detect gas concentration. The gas absorbs infrared within a specific range of light spectrum and the amount of absorption is directly proportional to the gas concentration.
Implementation Method 2
The conventional carbon dioxide sensor or analyzer uses non-dispersive infrared (NDIR) absorption to detect gas concentration.
