Solar Watch Transflective Plate Layout for Subdial Assemblability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar watches with subdials face challenges in improving design and assemblability due to the need for transflective plates on each subdial, which can make bonding members visible and degrade assembly efficiency.
Innovation Solution
A solar watch design with a transflective plate positioned between the solar cell and dial, featuring selectively placed regions overlapping subdials and decorative elements, ensuring the plate is integrated and hidden, enhancing assemblability and design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a transflective plate is attached only to the subdial portions to improve design, then the appearance is improved, but bonding members become visible which ruins the appearance
Solution Approach 1:
The transflective plate is divided into multiple separate pieces, with each piece corresponding to a specific subdial region. This segmentation allows the plate to be precisely positioned over subdials only, and the separate pieces can be individually attached and hidden beneath the dial structure, preventing bonding members from becoming visible while maintaining the aesthetic improvement.
2Shape
If a transflective plate is attached to each subdial to improve design, then the appearance is improved, but the number of attachment operations increases which degrades assemblability
Solution Approach 1:
Multiple separate transflective plate pieces corresponding to different subdials are integrated into a single dial component during assembly. By combining the attachment of multiple pieces into one assembly operation, the number of separate attachment steps is reduced, improving assemblability while still providing the aesthetic benefits of transflective coverage on all subdials.
3Illumination intensity
If a transflective plate is provided across the entire dial to improve light transmission, then light transmission is improved, but the decorative members and subdial design are compromised
Solution Approach 1:
The transflective plate is selectively applied only to specific subdial regions rather than the entire dial. This local application allows light transmission to be improved in the subdial areas where it is needed, while leaving the main dial area with its decorative members and overall design intact and visible, thus achieving light transmission improvement without compromising the overall design.
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 design improves assemblability by integrating the transflective plate with subdials, maintains a clear appearance, and enhances power generation efficiency through optimized light transmission.
Implementation Method 1
a transflective plate and a light-transmissive dial including a prism on its lower surface are superposed and arranged on top of a solar cell
