Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple pressure threshold alarm is implemented, then the device complexity is reduced, but the reliability of screen protection is insufficient because it cannot distinguish between different pressure scenarios
Solution Approach 1:
The pressure detection system is segmented into multiple pressure detection points arranged in arrays across the screen. Each point independently detects pressure, allowing the system to distinguish between localized point pressure (e.g., key pressing) and distributed pressure (e.g., palm resting). This segmentation enables more reliable screen protection by analyzing the spatial distribution of pressure rather than relying on a single threshold.
Solution Approach 2:
The system transitions from one-dimensional pressure threshold detection to two-dimensional spatial pressure distribution analysis. By detecting the positions, numbers, and distances between multiple force bearing points, the system adds spatial dimensionality to pressure monitoring, enabling differentiation between normal usage and potentially damaging pressure scenarios.
2Measurement precision
If multiple pressure detection points are used to improve protection accuracy, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The multiple pressure detection points serve multiple functions simultaneously: they detect pressure magnitude, determine pressure distribution patterns, calculate distances between force bearing points, and identify the number of contact points. This multi-functionality allows the system to achieve high measurement precision without proportionally increasing complexity, as the same detection infrastructure supports various analysis dimensions.
Solution Approach 2:
The patent combines multiple detection functions into a unified pressure detection system. Instead of having separate sensors for different measurement types, the system integrates pressure magnitude detection, position detection, and spatial relationship analysis into a single coordinated system, reducing overall complexity while maintaining precision.
3Adaptability or versatility
If a predetermined pressure value standard is set for alarm, then the ease of operation is improved, but the adaptability to different pressure scenarios is reduced
Solution Approach 1:
The alarm system dynamically adjusts protection criteria based on real-time pressure detection data. Instead of using a fixed predetermined threshold, the system evaluates multiple parameters including the number of force bearing points, their spatial distances, and pressure magnitudes. This dynamic adaptation allows the system to respond appropriately to various usage scenarios without requiring manual threshold reconfiguration.
Solution Approach 2:
The system changes multiple parameters simultaneously to adapt to different scenarios: it monitors pressure magnitude, number of contact points, and distances between points. By varying the protection criteria based on combinations of these parameters rather than a single fixed threshold, the system achieves high adaptability while maintaining ease of operation through automated multi-parameter evaluation.

AI summary
The present invention relates to a screen protection method and apparatus. The method comprises: acquiring a pressure state being experienced by a screen, the pressure state comprising one or more force bearing points and pressure values at the force bearing points; judging whether the pressure state being experienced by the screen reaches a predetermined state; and performing an alarm operation when the pressure state being experienced by the screen reaches the predetermined state. With the technical solution, an alarm operation may be performed according to the pressure state being experienced by the screen and a predetermined forewarning rule. This enables a user to timely know whether the screen is subjected to a pressure in the predetermined state and makes it easier for the user to timely take measures to reduce the pressure, thereby preventing the screen from cracking due to excessive pressure borne by the screen, preventing economic losses from being caused to the user and preventing the user's use of a smart device from being affected by the cracking of its screen.
