Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single magnifying glass or Fresnel lens is integrated into the bracelet, then the device is compact and portable, but the magnification power is limited and insufficient for observing very small details
Solution Approach 1:
The bracelet is divided into two separate strands, each containing a different optical device (first optical device with larger diameter, second optical device with smaller diameter). When superimposed, these segmented optical components work together to provide higher magnification than a single lens could achieve alone.
Solution Approach 2:
The second optical device is positioned within the optical path of the first optical device, creating a nested configuration where the smaller diameter second optical device is effectively nested within the larger diameter first optical device, forming a compound optical system.
2Measurement precision
If two optical devices with different diameters are superimposed to form a microscope, then magnification power is improved, but the device complexity increases
Solution Approach 1:
The bracelet structure serves multiple functions: it acts as a wearable accessory, a protective housing for the optical devices, and an alignment mechanism. The spacers and coupling means are integrated into the bracelet structure itself, eliminating the need for separate mounting components and reducing overall system complexity.
Solution Approach 2:
The optical alignment and positioning mechanisms are merged with the bracelet structure. The spacers are integrated into the strand design, and the coupling means are part of the bracelet's fastening system, combining structural support with optical alignment functions.
3Measurement precision
If the optical devices are made with precise spacing and alignment, then observation clarity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The spacers are pre-installed into the strands during manufacturing, establishing the correct spacing between optical devices before final assembly. This preliminary positioning ensures that when the strands are coupled together, the optical devices are automatically aligned at the correct distance without requiring high-precision final assembly.
Solution Approach 2:
The spacers act as intermediary elements between the first and second optical devices, physically maintaining the required spacing and alignment. These intermediary components absorb the manufacturing tolerances, allowing the optical devices themselves to be manufactured with standard precision while still achieving the required optical spacing.
4Ease of operation
If the optical devices are exposed for easy access, then ease of operation is improved, but the optical devices are vulnerable to damage
Solution Approach 1:
The strands themselves act as protective housings for the optical devices. The flexible or articulated nature of the strands allows them to conform to the wrist while providing a protective enclosure for the optical components, shielding them from direct impact while maintaining accessibility.
Solution Approach 2:
The optical devices are nested within the bracelet structure, with the first optical device integrated into the first strand and the second optical device integrated into the second strand. This nested configuration provides inherent protection while keeping the devices accessible through the bracelet's flexible structure.
