Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional light emitting structure is used, then the device can be simplified, but uniform light distribution over the strip kit cannot be achieved
Solution Approach 1:
The light distribution part is segmented into multiple grooves (first groove, second groove, third groove) with different depths and positions. Each groove acts as an independent light distribution channel, allowing precise control of light paths to achieve uniform illumination across the strip kit while maintaining a relatively simple overall structure.
Solution Approach 2:
Different regions of the light distribution part have different groove depths and configurations tailored to their specific light distribution needs. The first groove has a shallower depth for areas requiring less light diffusion, while the second groove extends deeper for areas needing enhanced light distribution, optimizing illumination uniformity without unnecessary structural complexity.
2Volume of moving object
If the apparatus is miniaturized, then portability is improved, but light distribution control becomes more difficult
Solution Approach 1:
The solution transitions from controlling light distribution in the horizontal plane to utilizing the vertical dimension through grooves of varying depths. By recessing grooves to different depths (second groove deeper than first, third groove deeper than second), the patent achieves precise light distribution control within a compact footprint, enabling miniaturization without sacrificing illumination uniformity.
3Illumination intensity
If grooves of equal depth are used, then manufacturing is simplified, but light distribution uniformity deteriorates
Solution Approach 1:
The patent deliberately employs asymmetric groove depths where the first groove has a shallower depth, the second groove has an intermediate depth, and the third groove has the greatest depth. This asymmetric configuration is optimized to compensate for variations in light emission patterns and achieve uniform light distribution across the strip kit, transforming a potential manufacturing challenge into a performance-enhancing feature.

AI summary
Provided is an apparatus for analyzing a bio-material. According to an embodiment of the inventive concept, the apparatus may include a light distribution part having grooves, a reflective layer provided on the grooves, and a light emitting part configured to emit light to the light distribution part. The grooves may be recessed from a top surface of the light distribution part, and sidewalls of the grooves may be inclined with respect to the top surface of the light distribution part. The grooves may include a first groove and a second groove. A distance between the light emitting part and the second groove may be greater than that between the light emitting part and the first groove, and a bottom surface of the second groove may be disposed at a level lower than that of a bottom surface of the first groove.
