Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If display devices with multiple pixels are used to output information visually, then information output capability is improved, but device complexity and manufacturing difficulty increase due to embedded circuits

Engineering Contradiction:
Improveinformation output capabilityVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts the information output function from complex display devices and implements it through simple tactile vibration mechanisms. Instead of using pixels and circuits to visually display information, the invention uses vibration motors that can be easily embedded in various devices to convey information through tactile feedback, thereby reducing device complexity while maintaining information output capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the visual display system (pixels, circuits, light emission) with a mechanical vibration system. The information is conveyed not through visual elements but through tactile vibrations generated by simple vibration motors, substituting a complex electromagnetic display system with a simpler mechanical actuation system

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If tactile information output is implemented for users with weakened senses, then accessibility is improved, but ease of operation deteriorates due to difficulty in controlling and driving the information output

Engineering Contradiction:
Improveaccessibility for users with weakened sensesVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The vibration motors in the patent are designed to automatically respond to input signals and generate appropriate tactile feedback without requiring complex user control. The system self-regulates the vibration patterns based on the input data, eliminating the need for users to manually control the information output mechanism and thereby improving ease of operation while maintaining accessibility

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If simple vibration motors are used for tactile output, then ease of manufacture is improved, but information output precision deteriorates due to limited control capability

Engineering Contradiction:
Improveease of manufactureVSAvoidinformation output precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent employs vibration motors with variable rotation speed capability, allowing the system to dynamically adjust the frequency and intensity of tactile vibrations based on the information being conveyed. This dynamic control enables precise information output while maintaining the simplicity of the vibration motor design, as the precision is achieved through control algorithms rather than complex mechanical structures

Inventive Principle:
Principle #15Dynamics
