Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users constantly access their smartphones through traditional input interfaces, then communication and professional tasks can be performed, but users must focus on the device screen and keypad, which is inconvenient and distracting

Engineering Contradiction:

Improveease of smartphone accessVSAvoidtime spent focusing on device

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent introduces a wristband as an intermediary device between the user and the smartphone. The wristband includes a touch surface that detects finger movements and a wireless communication unit that transmits commands to the smartphone, allowing users to control the smartphone without directly interacting with its screen or keypad.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical interaction with the smartphone's physical keypad and touch screen with a wireless gesture-based control system. The touch surface on the wristband detects finger movements and converts them into wireless commands, eliminating the need for direct mechanical interaction with the smartphone.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If a wristband with touch surface is used to control smartphone, then users can interact without looking at the device, but the wristband requires complex components including touch controller and wireless communication unit

Engineering Contradiction:

Improvehands-free smartphone controlVSAvoidwristband structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The wristband is designed to perform multiple functions: it serves as a wearable device, a gesture detection interface, a command processing unit, and a wireless communication device. This multi-functionality allows a single device to replace multiple separate components, managing complexity through integration.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the touch surface, touch controller, command processing unit, and wireless communication unit into a single integrated wristband device. This merging of functions into one wearable unit simplifies the user experience while managing the inherent complexity through consolidated design.

Inventive Principle:

Principle #5Merging (Combining)

3Measurement precision

If touch surface detects finger movements to generate commands, then smartphone control precision is improved, but the system requires accurate movement vector analysis

Engineering Contradiction:

Improvegesture detection accuracyVSAvoidtouch controller processing

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The touch controller is pre-programmed with algorithms to analyze movement vectors and translate them into specific smartphone commands. This preliminary preparation of processing logic allows the device to accurately interpret gestures without requiring complex real-time computation during actual use.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the detected finger movements to refine command generation. The touch controller continuously monitors the touch surface, analyzes movement patterns, and adjusts command transmission based on the detected gestures, creating a responsive control loop that improves precision.

Inventive Principle:

Principle #23Feedback
