Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional user interfaces are used in augmented reality environments, then users can interact with virtual elements, but the interaction becomes cumbersome and creates significant cognitive burden

Engineering Contradiction:

Improveease of interactionVSAvoidinterface complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically provides feedback about virtual object properties and states without requiring users to ask or search. The interface adapts to user needs by presenting relevant information proactively, reducing cognitive burden while maintaining interaction capability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements comprehensive feedback mechanisms that continuously inform users about virtual object properties, system state, and interaction outcomes. This feedback loop reduces uncertainty and cognitive load by keeping users informed without requiring active querying.

Inventive Principle:

Principle #23Feedback

2Productivity

If multiple input steps are required to achieve desired outcomes, then precise control is achieved, but interaction time increases and energy is wasted

Engineering Contradiction:

Improveinteraction efficiencyVSAvoidinteraction time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by anticipating user intent and preparing possible outcomes in advance. It can pre-load information, pre-position virtual objects, or prepare response options based on predicted user needs, reducing the steps required to achieve desired outcomes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The interface dynamically adapts the number and nature of required input steps based on context, user behavior patterns, and task complexity. For routine tasks, the system reduces steps through automation and shortcuts, while maintaining precision control when needed.

Inventive Principle:

Principle #15Dynamics

3Reliability

If complex manipulation of virtual objects is required, then precise control is achieved, but user errors increase and cognitive burden increases

Engineering Contradiction:

Improveinteraction accuracyVSAvoidease of manipulation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system implements error prevention mechanisms by designing interactions that are inherently difficult to execute incorrectly. Virtual objects are designed with clear interaction cues, and the system provides confirmation dialogs or undo capabilities before committing to irreversible actions, cushioning against user errors.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The interface uses visual changes including color variations to indicate object states, interaction possibilities, and selection status. These visual cues make complex manipulations more intuitive by providing clear feedback about what actions are available and what state the system is in.

Inventive Principle:

Principle #32Color changes

4Adaptability or versatility

If battery-operated devices are used for extended reality experiences, then portability is achieved, but energy consumption becomes a limiting factor

Engineering Contradiction:

Improvedevice portabilityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic action by implementing refresh rates and update frequencies that balance visual quality with power consumption. Instead of continuous high-rate updates, the system refreshes displays and processes inputs at optimized intervals, reducing energy usage while maintaining acceptable user experience.

Inventive Principle:

Principle #19Periodic action
