Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote control devices typically rely on binary input methods, which limit user interaction to simple on/off inputs, failing to provide nuanced control through varying force applications, such as light versus forceful touches, which can be beneficial for complex interactions with electronic devices.
Innovation Solution
A remote control device featuring a housing with a glass upper element having different frictionally engaging surfaces, including textured and smooth areas, equipped with a force sensing switch that includes a dome switch and strain gauges to measure force applied, allowing for analog input based on the amount of force, enabling multiple output states or signal levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If binary input buttons are used, then the device structure remains simple, but user interaction capability is limited
Solution Approach 1:
The patent transforms the binary input/output characteristic of traditional buttons into an analog input device that detects varying force levels. The force sensing switch converts mechanical force into proportional electrical signals, enabling multiple output states that correspond to different force magnitudes. This parameter change from binary to analog allows nuanced user interactions while maintaining a simple button-like external structure.
2Measurement precision
If traditional buttons are used, then manufacturing is simple, but input precision is limited to binary states
Solution Approach 1:
The patent replaces traditional mechanical switch mechanisms with a force sensing switch that uses strain gauges to detect force applied to the upper element. This substitution eliminates the need for complex mechanical linkages and multiple discrete components, simplifying manufacturing while enabling precise analog force measurement. The strain gauge-based detection system provides continuous force feedback rather than binary on/off states.

Enables users to perform nuanced interactions by detecting varying force levels, enhancing control over electronic devices with multiple output states, improving user experience and interaction capabilities beyond traditional binary inputs.
Implementation Method 1
One or more strain gauges can be positioned over at least one surface of the deflectable beam and configured to sense a strain in the deflectable beam based on the force applied to the textured surface
Implementation Method 2
The force sensing switch can include a dome switch disposed over a top surface of a deflectable beam, where the dome switch includes a deformable structure configured to deform when a force is applied to the first textured surface or to the second surface
