Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing controllers for portable electronic devices are either cumbersome when large or difficult to use accurately when small, often leading to inadvertent activation of wrong buttons or multiple buttons due to their size and layout.
Innovation Solution
A deformable, malleable controller that can be interacted with through arbitrary orientations, allowing users to provide input by pressing, rolling, or twisting, without the need for specific button presses, using a deformable outer shell with internal electrical contacts to signal commands to a portable electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the controller is made large, then it is easier to activate buttons accurately, but it becomes unwieldy and cumbersome to use
Solution Approach 1:
The controller employs a flexible membrane structure that can be deformed by user input. This membrane replaces traditional rigid buttons, allowing the controller to maintain a compact, portable form factor while still providing accurate input detection through membrane deformation patterns
Solution Approach 2:
The controller transitions from a static button layout to a dynamic membrane surface that responds to user manipulation. The membrane can be pressed, stretched, or deformed in various ways, and sensors detect these dynamic changes to determine user intent, providing accurate input without requiring large physical buttons
2Ease of operation
If the controller is made small, then it is more portable and convenient, but it becomes difficult to activate buttons accurately
Solution Approach 1:
The patent replaces traditional mechanical buttons with a membrane-based system detected by sensors. Instead of relying on physical button size and spacing, the system uses sensor arrays that can detect precise deformation patterns on the flexible membrane, enabling accurate input detection in a compact controller form factor
Solution Approach 2:
The controller changes the detection parameter from physical button position to membrane deformation characteristics. Sensors detect changes in membrane shape, tension, or position, allowing the system to distinguish between different user inputs based on deformation patterns rather than requiring large, spaced-out buttons
3Volume of moving object
If buttons are positioned closely together, then the controller can be smaller, but users may inadvertently activate wrong buttons or multiple buttons
Solution Approach 1:
The patent replaces discrete mechanical buttons with a continuous flexible membrane detected by sensors. This eliminates the problem of accidentally pressing adjacent buttons, as the membrane deformation can be precisely localized and interpreted by the sensor system, providing reliable input detection in a compact layout
Solution Approach 2:
The system creates a digital representation of the physical membrane deformation through sensor arrays. Multiple sensors work together to map the deformation pattern, allowing the system to accurately determine which area of the membrane was pressed even when buttons are positioned closely together

AI summary
A deformable controller for an electronic device, such as a portable electronic device, is disclosed. A user can interact with the controller to cause it to “deform” and thereby provide user input to control the electronic device. The controller can be malleable and symmetrical, and user interaction with the controller can be provided with substantially arbitrary orientation. In one embodiment, the controller is an in-line controller with a cable that couples to the electronic device. In one particular implementation, the portable electronic device can be a portable media player and the controller can remotely control media playback functions for the portable media player.
