Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control apparatuses for display devices require frequent button presses for directional control, making them inconvenient for users, as they need to manually manipulate key buttons to control the device's state.
Innovation Solution
Incorporating an inertial sensor-based measurement module within the control apparatus to measure motion due to external forces, generating signals that adjust the display device's state, allowing for control through motion rather than button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If button pressing operation is used for control, then control precision is maintained, but ease of operation deteriorates due to frequent manual manipulation required
Solution Approach 1:
The patent replaces the mechanical button pressing system with an inertial sensing system that detects motion and orientation changes of the control apparatus. The inertial sensor measures acceleration and orientation without requiring physical contact or manual manipulation of buttons, thereby substituting a mechanical interaction system with a sensor-based detection system that improves ease of operation while reducing control time
Solution Approach 2:
The control apparatus performs self-measurement of its own motion and orientation using the inertial sensor. The system automatically detects its spatial changes without requiring external input or manual button pressing, enabling the control apparatus to serve itself in measuring its state and generating corresponding control signals
2Ease of operation
If inertial sensor is added to measure motion, then ease of operation is improved through intuitive motion control, but device complexity increases due to additional measurement module
Solution Approach 1:
The inertial sensor serves multiple functions within the control apparatus: it measures both acceleration and orientation changes, generates control signals for various display device operations, and enables intuitive motion-based control. This multi-functionality allows a single added component to handle multiple control tasks, thereby improving ease of operation while minimizing the increase in device complexity
Solution Approach 2:
The inertial sensor acts as an intermediary between the user's physical motion and the control signals sent to the display device. It translates natural human movements into electronic commands, providing a smooth interface that improves ease of operation while keeping the added complexity contained within the sensor module rather than requiring complex mechanical or electronic systems
