Game Controller Button Placement Over NFC Antenna Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game controllers with contactless communication functions face challenges in operability due to the placement of operation buttons, which can be inadvertently pressed when using external storage devices, leading to erroneous operations and space inefficiency.
Innovation Solution
The game controller design incorporates a low-profile first operation button placement that overlaps with the antenna region, allowing for effective use of space and preventing accidental button presses, with the button positioned to avoid interference during contactless communication with external storage devices, and utilizing a two-layer substrate structure for compact design and improved freedom in design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an operation button is placed on the housing surface, then the button is easily accessible for operation, but the button may be erroneously pressed when an external storage device is placed in the antenna region
Solution Approach 1:
The operation button is positioned in the antenna region where it overlaps with the magnetic field area, utilizing the two-dimensional space on the housing surface to place the button precisely where it can be easily accessed while still being protected by the housing surface from accidental presses during contactless communication
2Adaptability or versatility
If space on the housing surface is maximized for button placement, then more functions can be added, but the risk of erroneous button presses increases when external devices are used
Solution Approach 1:
The housing surface is designed with differentiated local qualities: the antenna region has a specific magnetic field distribution that allows operation buttons to be placed within this area, while the housing surface itself provides a protective barrier that prevents erroneous presses, thus allowing functional expansion without increasing error risk
3Reliability
If the operation button is placed away from the antenna region, then erroneous presses are prevented, but space utilization efficiency decreases
Solution Approach 1:
The solution utilizes the two-dimensional plane of the housing surface to place the operation button within the antenna region's projected area, effectively using the available surface space without requiring additional three-dimensional volume, thus maximizing space utilization while maintaining reliability
