Solution Overview

Problem

Existing mobile devices do not effectively differentiate between drivers and passengers in moving vehicles, leading to unnecessary disabling of functions which can be inconvenient for passengers, and there is a need for a system that allows users to override safety features based on their specific situations.

Innovation Solution

A mobile device system that detects speed and provides users with notifications about impending function disablements, allowing them to override or accept safety feature activations, with options to set periods for notifications and feature status, ensuring safe use while accommodating different user scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mobile device functions are disabled when speed exceeds threshold, then driving safety is improved, but passenger convenience deteriorates

Engineering Contradiction:

Improvedriving safetyVSAvoidpassenger convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system applies different functionality restrictions to different users based on their role (driver vs. passenger). The mobile device determines whether it is being used by a driver or passenger and selectively disables functions only for drivers exceeding speed thresholds, while passengers retain full access to device functions.

Inventive Principle:

Principle #3Local quality

2Reliability

If mobile device functions are disabled when speed exceeds threshold, then distraction risk is reduced, but user flexibility deteriorates

Engineering Contradiction:

Improvedistraction risk reductionVSAvoiduser flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts device functionality based on real-time conditions (speed threshold, user role, override status). Rather than static disabling, the system continuously monitors speed and user input, enabling functions when appropriate conditions are met and disabling when safety concerns arise, allowing flexible adaptation to changing circumstances.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system provides feedback to users through notifications about impending function disablements and allows users to provide feedback through override inputs. This two-way communication enables users to express their intent and the system to adjust its behavior accordingly, maintaining safety while respecting user autonomy.

Inventive Principle:

Principle #23Feedback

3Reliability

If speed-based safety features are activated, then driving safety is improved, but device complexity increases

Engineering Contradiction:

Improvedriving safetyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mobile device performs self-monitoring of its own operational context (speed, usage pattern) and automatically applies appropriate safety restrictions without requiring external intervention. The device determines its own speed threshold violations and autonomously disables functions or prompts for user input, reducing the need for complex external monitoring systems.

Inventive Principle:

Principle #25Self-service
