Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer systems face inefficiencies in transitioning between multiple modes of operation, creating a cognitive burden on users and wasting energy, particularly in battery-operated devices, and lack intuitive interfaces for sharing between multiple users.
Innovation Solution
Implementing a computer system with modes of operation that include a first mode with full access, a guest mode with restricted access, and a locked mode, transitioning based on time thresholds and user detection, along with visual indicators for mode status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the computer system transitions between multiple modes of operation using conventional methods, then users can access different features and functions, but the transition process becomes cumbersome and creates cognitive burden on users
Solution Approach 1:
The system automatically detects user presence and transitions between modes without requiring explicit user commands. The computer system monitors sensor data to determine when a user approaches or leaves, and autonomously switches between locked, guest, and full-access modes, eliminating the need for users to navigate complex transition interfaces.
Solution Approach 2:
The patent replaces manual interface interactions (buttons, menus, gestures) with automated sensor-based detection. Instead of requiring users to physically interact with the interface to trigger mode transitions, the system uses sensors to detect user presence and automatically initiates mode changes, substituting mechanical user actions with automated electronic detection and response.
2Productivity
If the computer system waits for user input to transition between modes, then it can respond accurately to user intent, but the transition takes longer than necessary and wastes energy
Solution Approach 1:
The system performs preliminary detection of user presence using sensors before a full mode transition is required. By continuously monitoring sensor data in the background and preparing transition states in advance, the system can rapidly switch modes when user presence is detected, eliminating delays and reducing the need for prolonged high-power processing.
Solution Approach 2:
The system uses periodic sensor sampling to detect user presence rather than continuous monitoring. Sensors take measurements at regular intervals, and when a threshold number of consecutive readings indicate user presence, the system triggers a mode transition. This periodic approach reduces power consumption compared to continuous monitoring while maintaining responsive transition speed.
3Adaptability or versatility
If the computer system shares access between multiple users, then collaboration and accessibility are improved, but security and protection of sensitive data are compromised
Solution Approach 1:
The patent divides system access into distinct segmented modes: locked mode (no access), guest mode (limited access to specific features), and full-access mode (complete functionality). Each mode represents a security segment with defined boundaries. The system transitions between these segments based on detected user presence, allowing multiple users to access the device at different times with appropriate security restrictions for each user type.
Solution Approach 2:
The system introduces an automated user-detection intermediary that mediates between physical device sharing and data security. This intermediary layer detects user presence through sensors and automatically triggers mode transitions, acting as a mediator that enables device sharing while maintaining security boundaries. The intermediary eliminates the need for manual authentication while preserving security through automated mode management.
