Push-button Switch Display Screen Bright Rim Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push-button switches lack visual appeal due to fixed light sources and static indicating images, making them appear monotonous and unattractive in applications like vending machines and game machines.
Innovation Solution
A push-button switch with a display screen, such as an LCD or OLED, and light-emitting diodes that generate a bright rim around the periphery to highlight dynamic or non-dynamic images, enhancing the visual appeal by using a transparent top cover and a light-guiding member to direct light from the diodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional light source and static indicating image are used, then the structure is simple, but the visual appeal and attractiveness are poor
Solution Approach 1:
The patent applies the dynamics principle by replacing static indicating images with a display screen capable of showing dynamic images. The display screen can present changing visual content including animations and multiple colors, transforming the previously static visual indication into a dynamic display system that enhances attractiveness while maintaining structural simplicity through integrated circuit control.
Solution Approach 2:
The patent applies parameter changes by transforming the light source from a simple illumination function to a multi-functional element. The light-emitting diodes not only provide illumination but also generate a bright rim effect around the periphery, and their brightness can be dynamically adjusted. Additionally, the display screen parameters (colors, images, animations) can be changed through circuit control, enabling versatile visual appeal without complicating the overall structure.
2Adaptability or versatility
If a display screen and light-emitting diodes are added to create a bright rim, then the visual appeal is enhanced, but the device complexity increases
Solution Approach 1:
The patent applies the merging principle by integrating multiple functions into unified components. The light-emitting diodes serve dual purposes: providing illumination for the display screen and creating a bright rim effect around the periphery. The display screen itself serves both as an indicating image display and as a visual attraction element. This functional merging enhances visual appeal while avoiding the need for separate additional components that would increase structural complexity.
Solution Approach 2:
The patent applies the universality principle by designing components that perform multiple functions. The circuit board not only controls the display screen but also controls the light-emitting diodes, serving as a universal control unit. The light-emitting diodes function both as illumination sources and as decorative rim-lighting elements. This multi-functionality approach allows the system to achieve enhanced visual appeal without proportionally increasing device complexity, as existing components are utilized for multiple purposes.
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 creates a visually appealing and eye-catching appearance by highlighting the indicating images on the display screen with a bright rim, making the push-button switch more attractive and engaging.
Implementation Method 1
a circuit board with light-emitting diodes located in the recess below the light-guiding member. When the light-emitting diodes are turned on to emit light onto the light-guiding member, a bright rim is generated along the periphery of the top cover
Implementation Method 2
The post of the actuating member has a spring fitted therearound and is fitted in the sleeve of the seat to connect to the upper end of the microswitch. Thus, when the top cover is downward pushed, the spring is compressed and the microswitch is on, and when the top cover is released, the actuating member is returned to its home position by an elastic restoring force of the spring

AI summary
A push-button switch with display screen includes a seat having an open-topped recess, a top cover located in the recess, a display screen, such as an LCD, an OLED or a TFT-LCD, located in below the top cover, an actuating member located in the recess below the display screen and connected to a microswitch located below the seat, a frame-like light-guiding member located in the recess around a periphery of the top cover, and a circuit board with light-emitting diodes located in the recess below the light-guiding member. The display screen is connected to an external circuit for displaying different dynamic or non-dynamic indicating images. When the light-emitting diodes are turned on to emit light onto the light-guiding member, a bright rim is generated along the periphery of the top cover to highlight the indicating images on the display screen and give the push-button switch a beautiful eye-catching appearance.
