Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional calibration techniques are used, then the touch screen can be calibrated, but inaccuracies result due to improper scaling or alignment of the monitor active area
Solution Approach 1:
A physical frame is introduced as an intermediary tool between the monitor and touch screen during calibration. The frame provides reference markings that align with the monitor's active area boundaries, serving as a mediator to ensure accurate scaling and positioning. This physical reference system eliminates the imprecision of software-only calibration by providing tangible alignment guides.
Solution Approach 2:
The frame is prepared in advance with pre-marked reference points and alignment features before the calibration process begins. By establishing the correct active area boundaries and scaling references beforehand, the calibration process becomes a straightforward alignment task rather than a complex adjustment procedure, ensuring consistent results across different monitors.
2Illumination intensity
If the monitor active area is adjusted to improve visibility, then players can see better, but the touch screen becomes unreliable and information may not appear
Solution Approach 1:
The frame acts as a reference intermediary that defines the correct relationship between the visible monitor area and the touch-sensitive area. By aligning the frame's reference markings with the monitor's active area boundaries, the calibration process ensures that the visible display area matches the touch input area, maintaining both visibility and reliability.
Solution Approach 2:
The invention addresses the parameter mismatch between monitor display area and touch screen active area by using the frame to establish correct scaling parameters. The frame's reference markings provide the geometric parameters needed to adjust the monitor's active area settings, ensuring that the display parameters match the touch input parameters.
3Productivity
If manual calibration without reference tools is used, then calibration can be performed, but inconsistencies occur across similarly manufactured gaming terminals
Solution Approach 1:
The frame is designed as a universal reference tool that can be applied to any monitor of a given size and format. The same frame design works across multiple gaming terminals, ensuring that calibration procedures are consistent and produce uniform results across the entire fleet of devices, regardless of which specific terminal is being calibrated.
Solution Approach 2:
The frame provides a physical copy or representation of the correct active area boundaries and aspect ratio. By copying the ideal geometric relationships onto the frame, each calibration process replicates the same reference standards, ensuring consistency across all terminals without requiring complex software configurations for each device.
