Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing techniques are used to change output properties of illumination elements, then the device can adjust beam width and brightness, but the process becomes cumbersome and time-consuming requiring multiple key presses
Solution Approach 1:
The patent implements a lock screen interface that allows users to adjust illumination properties (beam width, brightness) before fully entering the device, performing the adjustment action in advance. This preliminary action eliminates the need to navigate through multiple screens after unlocking, directly reducing the time and steps required to change illumination properties.
Solution Approach 2:
The patent segments the illumination control functionality into distinct, easily accessible controls on the lock screen interface. By separating beam width adjustment, brightness adjustment, and flashlight activation into individual interactive elements, users can quickly access and modify specific properties without navigating through complex menus, improving ease of operation.
2Ease of operation
If existing techniques are used to change output properties of illumination elements, then the device can adjust settings, but the process consumes unnecessary device energy in battery-operated devices
Solution Approach 1:
By allowing users to adjust illumination properties on the lock screen before full device activation, the patent performs configuration actions when the device is in a lower-power state. This preliminary configuration reduces the need for prolonged high-power processing and screen updates that would occur if adjustments were made after full device wake, thereby conserving battery energy.
3Adaptability or versatility
If existing techniques are used to change output properties of illumination elements, then the device can modify beam width and brightness, but the interface becomes complex and increases cognitive burden on the user
Solution Approach 1:
The patent divides the illumination control interface into segmented, modular elements on the lock screen, with separate controls for beam width, brightness, and flashlight activation. This segmentation allows users to interact with individual properties independently, reducing cognitive load by presenting one control at a time rather than a complex unified interface, while still providing access to multiple adjustment capabilities.
Solution Approach 2:
The patent implements a dynamic lock screen interface that responds to user interactions by providing contextual controls. When a user taps or swipes on the lock screen, the interface dynamically reveals or adjusts illumination controls as needed, adapting the complexity of the interface to the user's immediate needs rather than presenting all controls simultaneously, thereby reducing perceived complexity while maintaining versatility.

AI summary
An electronic device displays on a display device, a user interface including a first user interface element, the first user interface element being associated with the illumination element, and detects a first input at a location corresponding to the first user interface element. In response to detecting the first input and in accordance with a determination that the first input meets first criteria, the device changes a beam width of a light beam emitted by an illumination element from a first beam width to a second beam width, wherein the second beam width is different from the first beam width.
