Casino Button Assembly With Low-Protrusion Detachable Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional button devices for casino machines protrude excessively from the display panel, causing image distortion and user wrist strain, and are difficult to assemble and disassemble.
Innovation Solution
A button device design featuring a detachable fastening mechanism using hooks and interference protrusions, allowing for minimal protrusion height, easy assembly, and reliable disassembly, with a bezel that covers the push button and is securely coupled to a base with hooks and interference protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the button device is fixedly disposed to overlap the image to create a three-dimensional effect, then the visual effect is improved, but the protrusion height increases causing image distortion and wrist strain
Solution Approach 1:
The button device is segmented into multiple components: a base plate mounted on the display, a push button with central portion and flange portion, and a bezel. This segmentation allows the protrusion to be distributed and controlled, minimizing the overall height while maintaining the visual effect.
Solution Approach 2:
The design transitions from a purely vertical protrusion to a multi-dimensional structure where the flange portion extends horizontally and the bezel provides lateral support. This dimensional change allows the button to achieve the three-dimensional visual effect without excessive vertical height.
2Ease of operation
If the protrusion height is minimized to reduce image distortion and wrist strain, then user comfort is improved, but the assembly and disassembly reliability may be compromised
Solution Approach 1:
The interference protrusions on the bezel automatically engage with the hooks on the base plate during assembly, providing self-aligning and self-locking functionality. This self-service mechanism ensures reliable assembly without requiring complex tools or procedures, even with minimal protrusion height.
Solution Approach 2:
The interference protrusions act as intermediary elements between the bezel and base plate, providing a reliable connection mechanism that enables both secure assembly and easy disassembly. These protrusions mediate the connection, ensuring reliability while maintaining ease of operation.
3Ease of repair
If a detachable fastening mechanism is used to simplify assembly and disassembly, then ease of maintenance is improved, but the structural complexity increases
Solution Approach 1:
The fastening mechanism is segmented into discrete hooks on the base plate and corresponding interference protrusions on the bezel. This segmentation allows for simple, modular components that are easy to manufacture and assemble, reducing overall structural complexity while enabling easy maintenance.
Solution Approach 2:
Instead of using a complex locking mechanism that requires tools for assembly, the design inverts the approach by using interference protrusions that naturally engage with hooks during simple press-fit assembly. This inversion simplifies the assembly process while maintaining secure fastening.

AI summary
A button device for casino machines is provided including a base installed to overlap a display panel of a display device, a push button that overlaps the base and is disposed to move vertically with respect to the base, and has a central portion through which an image displayed on the display panel is visible and a flange portion that is stepped at an outer boundary of the central portion and extends outward, and a bezel that covers the push button so that the central portion is exposed and the flange portion is hidden, and is detachably coupled to the base.
