Electronic Device With Projecting Buttons for One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face issues with button mix-ups and difficulty in simultaneous operation, especially when multiple buttons are located on one side, leading to potential drops due to poor ergonomic design.
Innovation Solution
The electronic device incorporates projecting portions on the upper surface with inclined buttons arranged to minimize mix-ups and require minimal finger bending, allowing easy simultaneous operation and reducing the likelihood of drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple operation buttons are arranged on one side of the upper surface, then the device can be operated with one hand, but users may experience button mix-ups and difficulty in simultaneous operation
Solution Approach 1:
The upper surface is divided into a projecting portion and a non-projecting portion, with different buttons arranged on each portion. This segmentation creates distinct operational zones that prevent button mix-ups while maintaining one-handed operation capability.
Solution Approach 2:
The projecting portion is provided with a different surface level compared to the non-projecting portion, creating local quality differences. This elevation difference helps users distinguish between button zones and prevents accidental misoperation while keeping all buttons accessible to one hand.
2Device complexity
If buttons are arranged on a flat upper surface, then the structure is simple, but fingers must bend greatly to reach buttons located on one side
Solution Approach 1:
The upper surface transitions from a two-dimensional flat plane to a three-dimensional structure with a projecting portion. This dimensional change brings buttons closer to the user's fingers, reducing the need for extreme finger bending while maintaining structural simplicity.
3Shape
If the upper surface is flat without projections, then the device has a sleek design, but the device may be dropped when held vertically
Solution Approach 1:
The projecting portion acts as an intermediary element between the user's hand and the device body. When the device is held vertically, the projecting portion protrudes from the hand, preventing the device from slipping or being dropped while maintaining a relatively sleek overall design.

AI summary
An electronic device includes a front surface, a rear surface, an upper surface, a lower surface, a first side surface, a second side surface, a first operation button, and a second operation button. A display is arranged at the front surface. The rear surface is located opposite to the front surface. The upper surface is contiguous to the front surface and the rear surface. The lower surface is located opposite to the upper surface. The first side surface is contiguous to each of the front surface, the rear surface, the upper surface, and the lower surface. The second side surface is located opposite to the first side surface. The upper surface is provided with a projecting portion. The first operation button is arranged at the projecting portion and provided closer to the first side surface relative to a center of the upper surface.
