Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional lens splicing method is used for button indicator, then the structure is simple, but the assembly process is complex and time-consuming
Solution Approach 1:
The light guiding ring is nested within the button cover structure, with the button cover serving as an outer shell that contains and protects the light guiding ring. The light guiding ring fits precisely within the button cover's internal cavity, creating a nested configuration that simplifies assembly while maintaining structural integrity.
Solution Approach 2:
The button indicator is divided into distinct functional segments: the button cover with retaining walls and hooks for structural support and assembly, and the separate light guiding ring with light guiding portions for optical function. This segmentation allows independent manufacturing and simplified assembly of the two components.
2Illumination intensity
If light guiding portions are added to improve light distribution, then luminous efficiency improves, but manufacturing complexity increases
Solution Approach 1:
The light guiding ring features localized light guiding portions at specific positions rather than uniform modification throughout. These light guiding portions are strategically placed to direct light distribution where needed, achieving uniform illumination while minimizing the overall complexity of the manufacturing process.
3Illumination intensity
If multiple light sources are used to achieve uniform illumination, then light distribution improves, but cost and energy consumption increase
Solution Approach 1:
The light guiding ring acts as an intermediary component between the light source and the external environment. It receives light from the light source and redistributes it uniformly through its light guiding portions, achieving uniform illumination with a single light source rather than requiring multiple light sources.
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 enables easy assembly, enhanced light efficiency by reducing leakage, and achieves over 70% uniformity in light emission, potentially reducing the number of required light sources and lowering costs.
Implementation Method 1
The elastic arms are adapted to abut against the bottom surface of the cover body
Implementation Method 2
the light guiding portions are grooves, and an arc angle of each of the grooves ranges from 91 degrees to 101 degrees
Implementation Method 3
the outer surface of the ring body is an inclined surface, and an angle between the inclined surface and an horizontal plane ranges from 111 degrees to 117 degrees
