Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch sensor is used to control display apparatus functions, then the operation interface can be simplified, but touch inputs from insulators cannot be recognized
Solution Approach 1:
The patent combines multiple input detection methods (touch sensor and jog switch) into a single integrated input unit. This allows the system to detect both conductive touches and insulator touches by switching between different detection modes, thereby maintaining reliability for all user inputs while preserving interface simplicity.
Solution Approach 2:
The input unit is designed to perform multiple functions: it can operate as a touch sensor for conductive inputs and as a jog switch for insulator inputs. This multi-functionality ensures that all types of user interactions (fingers, styluses, insulator objects) can be reliably recognized without requiring separate control mechanisms.
2Reliability
If jog switches or tact switches are used for controlling display apparatus, then reliable input recognition is achieved, but manufacturing costs increase and circuit board area requirements increase
Solution Approach 1:
A single input unit structure serves dual purposes: functioning as both a touch sensor and a jog switch depending on the detection mode. This eliminates the need for separate jog switch components, reducing manufacturing costs and circuit board area while maintaining reliable input recognition for all input types.
Solution Approach 2:
The system changes operational parameters (detection mode, sampling frequency, threshold values) based on the type of input detected. By dynamically adjusting these parameters, the single input unit can reliably recognize both conductive and insulator touches without requiring additional hardware components.
3Reliability
If jog switches or tact switches are used for controlling display apparatus, then reliable input recognition is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the touch sensor and jog switch into a single integrated input unit with unified control logic. This consolidation reduces device complexity by eliminating the need for separate control circuits and processing paths for different input types, while maintaining reliable recognition through mode switching.
4Ease of operation
If a single input device is used to operate display apparatus, then operation becomes more intuitive and easy, but the system must handle diverse input types effectively
Solution Approach 1:
The single input unit is designed with universal detection capabilities that can identify and process multiple input types (conductive touches, insulator touches, press duration, press intensity). This versatility allows the system to maintain operational intuitiveness while effectively handling diverse user interactions through a unified interface.
Solution Approach 2:
The system dynamically adjusts detection parameters based on the input characteristics. By monitoring factors such as touch duration, press intensity, and electrical conductivity, the system adapts its response to provide intuitive operation for different input types while maintaining effective control through the single input device.
