Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If laser projection systems are used to create optical markings on a surface, then precise positioning for drilling and welding can be achieved, but these systems require a projection surface and cannot be used for arranging three-dimensional objects in space
Solution Approach 1:
The patent transitions from two-dimensional surface projection to three-dimensional spatial positioning by using the intersection of two laser beams in space. The positioning line is created at the intersection point of two laser beams with different spatial orientations, enabling direct 3D object arrangement without requiring a projection surface.
Solution Approach 2:
Fog or aerosol is introduced as an intermediary medium to make the laser beam intersection visible. The fog particles scatter the laser light, allowing the positioning line in space to be observed without requiring a solid projection surface, thus enabling 3D spatial positioning.
2Ease of operation
If fog is used to make the positioning line visible in space, then no scattering or reflecting surface is needed, but the visibility depends on the presence of fog or aerosol
Solution Approach 1:
Fog or aerosol serves as an optical intermediary that scatters laser light to make the positioning line visible. This mediator enables visibility in free space without requiring solid surfaces, though it does require the presence of dispersed particles in the air.
Solution Approach 2:
The patent uses laser beams with different wavelengths (colors) that overlap to create a distinct positioning line color. For example, red and yellow laser beams create an orange positioning line, making it distinguishable from the background fog and improving visibility.
3Difficulty of detecting and measuring
If laser beams with different wavelengths are used to create a colored positioning line, then the positioning line can be distinguished from background light scattered by fog, but the system requires multiple laser sources with different wavelengths
Solution Approach 1:
The patent employs laser beams with different wavelengths that overlap to create a positioning line with a distinct color different from the individual beams. This color differentiation makes the positioning line easily distinguishable from the white background light scattered by fog, improving detectability.
Solution Approach 2:
Multiple laser beams with different wavelengths are merged at the intersection point to create the positioning line. The combination of different colored lasers produces a unique color that stands out against the background, enhancing visibility and detectability.
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
Enables precise alignment and orientation of three-dimensional objects in space, particularly useful for tasks like laying pipelines, with the ability to distinguish the positioning line from background light, reducing costs through software implementation.
Implementation Method 1
two laser beams from different directions are brought together at an intersection point, and the positioning line in space is generated by moving the intersection point
Implementation Method 2
the positioning line is made visible by means of fog. This is advantageous because the positioning line can be made visible in this way without a scattering or reflecting surface
