Solution Overview
Problem
Mobile communications devices face energy depletion due to backlighting, which is necessary for readability but consumes significant battery charge, and existing customization options for functions like sounds and display settings are not optimized for specific tasks or user preferences.
Innovation Solution
A function-control instruction system that allows remote or local generation and execution of instructions to control device functions, such as backlighting and sounds, based on user information or calibration data, enabling dynamic adjustment of device settings according to user needs, such as reading speed or location-specific content retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If backlighting is activated to improve display readability, then display visibility is improved, but battery charge depletes more quickly
Solution Approach 1:
The patent implements dynamic backlight control where the backlight duration and intensity are automatically adjusted based on user reading speed calibration. The system calibrates by timing how long users take to read standardized text blocks, then uses this data to optimize backlight timing - providing sufficient illumination for the actual reading duration needed while turning off earlier than fixed settings to conserve battery energy.
Solution Approach 2:
The system changes the backlight timing parameter from fixed predetermined values to dynamically calculated values based on measured user reading speed. By converting reading speed measurements into optimized backlight duration parameters, the system adapts the illumination timing to match actual user needs, reducing unnecessary energy consumption while maintaining adequate visibility.
2Adaptability or versatility
If device functions are customized for specific tasks and users, then user experience is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service customization where the device automatically calibrates user-specific parameters by measuring reading speeds during initial use. The system performs self-calibration by timing user reading of test text, automatically calculating optimal backlight durations, and configuring device functions without requiring manual user setup or complex configuration interfaces, thereby reducing perceived complexity while maintaining high adaptability.
Solution Approach 2:
The system performs preliminary calibration actions during initial device setup or idle periods, measuring user reading speed in advance and pre-configuring optimized function parameters before actual use. This preliminary measurement and configuration approach eliminates the need for complex real-time adjustments during task execution, simplifying the user experience while achieving personalized customization.

AI summary
Function-control instructions for controlling a function or feature of a device can be created remotely, locally, or both. A device can receive a function-control instruction or a function-control instruction embedded in received content. Additionally, or alternatively, a function-control instruction can be created locally based on user information or calibration information. Function-control instructions can be passed to an instruction execution application that interprets the function-control instruction. The instruction execution application can pass instructions, based on the function-control instruction, to the device for implementation.
