Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display devices are used in a portable computing device, then the display area and functionality are improved, but perceived color differences and visual consistency deteriorate due to variations in ambient lighting and temperature
Solution Approach 1:
The patent applies local quality by implementing separate sensor systems (ambient light sensors, temperature sensors, color sensors) for each display device to detect local environmental conditions. Each display's color parameters are adjusted independently based on its specific ambient conditions, ensuring that each display adapts to its local environment while maintaining overall visual consistency across the multi-display system.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting color parameters (gamma, chroma, brightness) of each display device based on sensor data. The system modifies these parameters in response to detected ambient light levels, temperature variations, and color temperature differences, thereby maintaining color consistency across displays despite environmental variations.
2Stability of the object's composition
If color adjustments are performed based on ambient light and temperature data, then color consistency between displays is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent applies periodic action by implementing color adjustments at specific intervals or under specific conditions rather than continuously. The system monitors ambient light and temperature sensors and performs color parameter adjustments when significant environmental changes are detected, rather than constantly adjusting, thereby reducing power consumption while maintaining color consistency.
Solution Approach 2:
The system implements self-service by using onboard sensors (ambient light sensors, temperature sensors, color sensors) to automatically detect environmental conditions and trigger color adjustments without user intervention. The displays self-regulate their color parameters based on detected conditions, reducing the need for manual calibration and minimizing the computational overhead required for continuous monitoring and adjustment.
3Measurement precision
If color sensors, ambient light sensors, and temperature sensors are added to each display device, then perceived color differences are reduced, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies universality by implementing a standardized sensor suite (ambient light sensor, temperature sensor, color sensor) that is integrated into each display device module. This multi-functional sensor system serves multiple purposes: detecting ambient light levels for brightness adjustment, measuring temperature for thermal compensation, and sensing color temperature for white point calibration. By consolidating these functions into a unified sensor system, the patent reduces overall system complexity while maintaining high measurement precision.

AI summary
In some examples, a computing device includes a first display device coupled to a second display device by hinges. After determining that the computing device has been moved from a first orientation to a second orientation, the computing device may receive ambient light data from ambient light sensors associated with the first and second display device, temperature data from temperature sensors associated with the first and second display device, and color data from color sensors associated with the first and second display device. After determining that power is being received from an external power source or that the user prefers the display devices may be color matched, the computing device may perform one or more color adjustments based on the ambient light data, the temperature data, and the color data, thereby reducing a difference in a perceived color between the first display device and the second display device.
