Sensor Adjustment for Foldable Device Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is that the sensor response policy of non-foldable devices cannot be directly applied to foldable devices due to their unique hardware structure and changing environmental conditions, leading to potential sensor non-response or response errors.
Innovation Solution
A sensor adjustment method and apparatus that involves obtaining a folding status parameter, invoking a corresponding sensor adjustment policy, and performing adjustments to the sensor operating parameters or data preprocessing to mitigate interference caused by device folding.

Engineering Contradiction Analysis
1Ease of manufacture
If a sensor response policy of a non-foldable device is directly applied to a foldable device, then the existing sensor response policy can be used without modification, but the sensor usually has no response or a response error due to device folding
Solution Approach 1:
The patent applies dynamics by making the sensor adjustment policy changeable according to device folding status. The system dynamically adjusts sensor parameters based on real-time folding state detection, transitioning from a static non-foldable device policy to a dynamic foldable-aware policy that adapts to different device configurations.
Solution Approach 2:
The patent implements parameter changes by modifying sensor operating parameters (such as sampling rate, threshold values, or detection ranges) based on the folding status parameter. This allows the sensor to maintain accurate response across different device states without requiring complete policy redesign.
2Measurement precision
If sensor adjustment policies are generated for different folding status parameters, then sensor response accuracy is improved, but the complexity of policy generation and management increases
Solution Approach 1:
The patent applies segmentation by dividing the sensor adjustment policy into multiple discrete policies corresponding to different folding status parameters. Each policy is tailored for a specific folding state (e.g., folded, unfolded, partially folded), making the complex adaptation problem manageable through structured segmentation.
Solution Approach 2:
The patent implements feedback by using the folding status parameter to automatically select and apply the appropriate sensor adjustment policy. The system continuously monitors device folding state and adjusts sensor parameters in real-time based on feedback from the device's physical configuration, eliminating the need for manual policy switching.
3Measurement precision
If data preprocessing is performed on first sensor data to eliminate interference, then sensor data accuracy is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by pre-generating sensor adjustment policies for different folding status parameters before runtime. The interference elimination algorithms and correction factors are prepared in advance, allowing the system to quickly apply pre-computed adjustments rather than performing complex real-time calculations during sensor data processing.

AI summary
A sensor adjustment method includes obtaining a folding status parameter, where the folding status parameter is used to describe a folding extent of a foldable device, and where a component of the foldable device in a folded state causes interference to a first sensor of the foldable device compared with a non-folded state; invoking a sensor adjustment corresponding to the folding status parameter; and adjusting a sensor operating parameter of the first sensor according to the sensor adjustment and/or performing data preprocessing on first sensor data collected by the first sensor.
