Overlapping Operation Button Layout for Better Input Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Some users are not satisfied with the operational comfortability of conventional input devices.
Innovation Solution
An input device with a first operation button and a second operation button, where the second button has an extended portion covering part of the first button's surface, allowing for improved user comfort through enhanced surface area and ergonomic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation button surface area is increased to improve user comfort, then operational comfortability is improved, but the device structure becomes more complex
Solution Approach 1:
The second operation button includes an extended portion that covers part of the first operation button's upper surface portion. This nested configuration allows the buttons to share space efficiently, increasing the effective operation surface area and improving user comfort while avoiding a proportional increase in overall device complexity. The extended portion integrates with the existing button structure rather than adding a completely separate component.
2Ease of operation
If an extended portion is added to the second operation button, then user comfort is enhanced, but manufacturing complexity increases
Solution Approach 1:
The extended portion of the second operation button is integrated into a single molded piece with the main button body. This combining of the extended portion and the button body into one manufacturing unit simplifies production compared to assembling separate components, while still providing the ergonomic benefits of the extended surface area for improved user comfort.

AI summary
Provided is a novel input device capable of improving operational comfortability for users not satisfied with operational comfortability of conventional input devices. A controller includes a main body, a first operation button attached to the main body, and a second operation button attached to the main body at a position different from a position at which the first operation button is attached. The first operation button includes an upper surface portion that constitutes an operation portion operated by a user. The second operation button includes an upper surface portion constituting an operation portion operated by the user, and includes an extended portion that is provided at a part of the upper surface portion of the second operation button and that covers a part of the upper surface portion of the first operation button.
