Dual-Axis Pivoting Button Cap for Portable Electronic Device Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices with single-axis key devices lack flexibility in operation, limiting user input options.
Innovation Solution
A dual-axis actuated key device with a button cap that pivots along two perpendicular axes, allowing user input through either the first or second cap body to activate a switch, enhancing operational flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-axis key device is used, then the device structure is simple, but the operational flexibility is limited
Solution Approach 1:
The patent transitions from a single-axis pressing mechanism to a dual-axis rotation mechanism. The button cap can rotate around a first axis (longitudinal axis) and a second axis (lateral axis), enabling operations in multiple directions including diagonal presses, thereby adding dimensional freedom to the input mechanism and resolving the contradiction between operational flexibility and structural simplicity.
2Adaptability or versatility
If a dual-axis button cap is implemented, then operational flexibility is enhanced, but the device complexity increases
Solution Approach 1:
The button cap is designed as a dynamic component that can rotate around two perpendicular axes rather than being a fixed single-axis structure. This dynamic capability allows the button to adapt to different input directions (front, side, diagonal) while maintaining a relatively simple overall structure, thus enhancing input options without proportionally increasing device complexity.

AI summary
A portable electronic device includes a casing with a casing pivotal portion and a key device. The key device is installed on the casing and includes a button cap. The button cap includes a cap pivotal portion, a first cap body and a second cap body. The cap pivotal portion is pivoted to the casing pivotal portion. The first cap body extends from the cap pivotal portion along a first axis. The second cap body extends from the first cap body along a second axis. The button cap rotates in an activating direction when the first cap body is applied by an external force along the first axis or when the second cap body is applied by the external force along the second axis.
