Touch-Sensitive Keypad Integration for Gesture and Press Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keypad control devices are inadequate for operating diverse user interfaces, particularly window-type interfaces, as they lack the necessary input capabilities and flexibility.
Innovation Solution
A touch-sensitive keypad control device that integrates a touch control surface and a movable keypad, allowing for multiple input commands through gestures, sliding operations, and pressing actions, enabling control of devices with both touch and keypad functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional keypad control device with pushing keys is used, then the device structure is simple and easy to manufacture, but it lacks the capability to operate window-type user interfaces and diverse user interfaces
Solution Approach 1:
The patent combines a touch control device and a keypad device into a single integrated control device. The touch control device includes a touch-sensitive surface that can detect gestures, while the keypad device provides physical push buttons. This merging allows the device to handle both touch-based window interface operations and traditional keypad inputs, resolving the contradiction between versatility and structural simplicity.
Solution Approach 2:
The integrated control device is designed to perform multiple functions: it can detect sliding gestures on the touch-sensitive surface for window interface navigation, detect pressing operations on the keypad for traditional control commands, and generate different control commands based on the input type. This multi-functionality enables the device to operate diverse user interfaces while maintaining a unified structure.
2Ease of operation
If a touch control device with an uncovered touch-sensitive surface is used, then the ease of operation for gestures is improved, but the device becomes more complex compared to a simple keypad
Solution Approach 1:
The touch control device and keypad device are merged into a single integrated unit where the keypad device is disposed on the touch-sensitive surface. This combination allows the device to provide both gesture-based touch control and physical keypad input within one unified structure, improving ease of operation for diverse interfaces while managing complexity through integration rather than separate components.
3Adaptability or versatility
If a keypad device is integrated with the touch control device, then multiple input capabilities are achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent integrates the keypad device directly onto the touch-sensitive surface of the touch control device, forming a unified control device. This merging approach enables multiple input capabilities (touch gestures and physical key presses) while streamlining the manufacturing process by reducing the number of separate components and assembly steps compared to using separate touch and keypad devices.

AI summary
A touch-sensitive keypad control device for use with a controlled device is provided. The touch-sensitive keypad control device includes: a housing, a touch control device disposed in the housing, and a keypad device uncovered from the housing and disposed above the touch control device. The touch control device generates a first command for controlling the controlled device in response to a gesture of a user relative to the keypad device, and the keypad device generates a second command for controlling the controlled device in response to a level change of the keypad device relative to the housing in response to a pressing operation of a user.
