Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional push switch structure is used with LEDs arranged on either side of the stem, then the switch can perform basic switching functions, but the light emission and visibility are not enhanced effectively
Solution Approach 1:
The patent combines the light-emitting element with the resilient member by positioning the LED at the center of the concave shape and integrating the light guide function directly into the resilient member structure. This merging of switching and light guidance functions into a single integrated component enhances light emission visibility while avoiding the need for separate complex light guide mechanisms.
Solution Approach 2:
The patent introduces a light guide member as an intermediary component that transfers light from the LED at the center of the resilient member to the key top. This light guide member acts as a mediator to distribute and enhance light emission visibility across the key top surface, improving illumination effectiveness.
2Ease of operation
If LEDs are arranged on either side of the stem in the housing, then the switch can provide light indication, but the light transmission and visibility enhancement are limited
Solution Approach 1:
The patent employs a concave shape in the resilient member to focus and direct light emission. The curved surface of the concave shape helps concentrate and guide light from the central LED upward, enhancing light transmission effectiveness and visibility when the switch is pressed.
Solution Approach 2:
The patent transitions from arranging LEDs horizontally on either side of the stem to positioning a single LED vertically at the center of the concave shape. This dimensional repositioning allows light to be directed upward through the key top, creating enhanced visibility in the vertical dimension rather than lateral distribution.
3Illumination intensity
If a light guide mechanism with multiple light guiding members is used, then light can be guided effectively, but the device complexity increases
Solution Approach 1:
The patent merges the light guide function with the resilient member itself, eliminating the need for separate first and second light guiding members. The resilient member's concave shape and integrated structure serve both as the switching mechanism and as the light guide, significantly reducing device complexity while maintaining effective light guidance.
Solution Approach 2:
The resilient member is designed to perform multiple functions simultaneously: it serves as the switching component that connects electrodes when pressed, and as the light guide member that directs light from the LED to the key top. This multi-functionality reduces the overall number of components and simplifies the device structure.
