Touch Panel Apparatus Knob Sensor Priority Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panel apparatuses either disable touch operations during dial operations or utilize inefficient sensor configurations, where a separate sensor is required for detecting knob operations, leading to suboptimal utilization of sensors.
Innovation Solution
A touch panel apparatus with a touch operation unit, a rotating operation unit, and detectors that prioritize operations based on input from touch sensors on the rotating unit's surface, ensuring accurate command output and efficient sensor utilization by determining the number and position of finger touches on the knob's surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate sensor is provided for detecting the touch of the operation knob, then the touch operation can be disabled during dial operation, but the sensor utilization becomes inefficient
Solution Approach 1:
The touch sensors on the outer peripheral surface of the rotating operation unit serve dual purposes: they detect both the touch operation of the rotating unit and the touch operation of the touch operation unit. By making the sensors universal, the patent eliminates the need for separate sensors while maintaining reliable operation priority determination through the controller's analysis of sensor patterns
2Reliability
If touch operation is disabled during dial operation, then operation priority can be determined, but the touch operation unit cannot respond to simultaneous touch inputs
Solution Approach 1:
The system dynamically adjusts its operation mode based on real-time sensor input patterns. The controller analyzes the number and position of touched sensors to determine whether the user intends to operate the rotating unit or the touch operation unit, enabling flexible adaptation to different user intentions rather than rigidly disabling one operation mode
3Measurement precision
If multiple touch sensors are disposed along the circumferential direction, then the number and position of finger touches can be detected, but the device complexity increases
Solution Approach 1:
The outer peripheral surface of the rotating operation unit is segmented into multiple discrete touch sensor positions arranged circumferentially. This segmentation enables precise detection of touch position and finger count, while the sensors are integrated into the existing rotating unit structure, avoiding additional complex components

Function Achieved in This Case
Enables prioritization of intended operations, preventing erroneous touch cancellations and optimizing sensor usage by accurately differentiating between touch screen and knob operations, thus enhancing user intent recognition and reducing accidental operation invalidations.
Implementation Method 1
The second detector includes a plurality of touch sensors disposed on an outer peripheral surface of the rotating operation unit
Data Source
AI summary
A touch panel apparatus including a first detector detecting a first operation of a touch operation unit, a second detector detecting a second operation of a rotating operation unit disposed close to the touch operation unit, and a microprocessor performing making a determination whether to prioritize the first or second operation, and outputting an operation command corresponding to the first or second operation in accordance with the determination. The second detector includes six or more touch sensors disposed on an outer peripheral surface of the rotating operation unit, and the microprocessor performs outputting the operation command corresponding to the first operation when the first operation is detected, while not outputting the operation command corresponding to the first operation even if the first operation is detected when the touch operation over a predetermined area on the outer peripheral surface is detected by the touch sensors.
