Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home control systems require manual interaction with devices or remote controls to manage lighting, audio, temperature, and other settings, lacking intuitive and seamless touch-based control solutions.
Innovation Solution
A touch-based control device with a control module and exterior panel that detects and interprets touch inputs on any location, utilizing capacitive sensors and gesture recognition to control connected devices such as lights, thermostats, and appliances, allowing for intuitive control through gestures and touch inputs on a wall-mounted interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual interaction with devices or remote controls is used, then control functionality is achieved, but user convenience and intuitiveness deteriorate
Solution Approach 1:
The patent replaces mechanical switches and physical remote controls with a capacitive touch interface that detects touch gestures through electrical field changes. The exterior panel with capacitive sensors substitutes traditional mechanical interaction mechanisms, allowing users to control devices through touch gestures without physical contact with switches or remote controls.
Solution Approach 2:
The control device integrates multiple control functions into a single universal interface. The exterior panel can detect various touch gestures (tap, swipe, press duration) to control different types of devices (lights, thermostats, appliances) with a single device, eliminating the need for separate remote controls for each function.
2Ease of operation
If touch sensors are integrated into the exterior panel, then ease of operation improves, but manufacturing complexity increases
Solution Approach 1:
The control device is divided into modular components: an exterior panel module containing capacitive sensors and a control module with processing circuitry. This segmentation allows the touch interface to be manufactured as a separate unit that can be integrated into existing control device housings, simplifying the overall manufacturing process while maintaining touch functionality.
Solution Approach 2:
The capacitive sensors in the exterior panel detect changes in electrical field parameters (capacitance values) when touched. By monitoring these parameter changes, the system can distinguish between different touch gestures (tap, swipe, long press) without requiring complex sensor arrays, thereby reducing manufacturing complexity while maintaining ease of operation.

AI summary
A touch-based control device can include an exterior panel that includes a groove region and a surrounding region, one or more touch sensors for detecting touch inputs performed anywhere on a substantial portion of the exterior panel, and a sensing module comprising one or more processors to detect, via the one or more touch sensors, touch inputs performed by a user on the exterior panel. The sensing module can interpret the touch input based on at least one of (i) a region where the touch input occurred, or (ii) a type of the touch input, and control a connected device based on the interpreted touch input.
