Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If various buttons and manipulators are provided for selecting functions and options, then the home appliance can provide various functions, but the manipulation becomes difficult for users not familiar with the operation

Engineering Contradiction:
ImprovefunctionalityVSAvoidmanipulation difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical button manipulation with voice-based speech recognition control. The microphone unit captures user speech, which is then processed by a speech recognition algorithm to execute corresponding functions, eliminating the need for physical manipulator interaction while maintaining full functionality access.

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

Solution Approach 2:

The patent introduces speech recognition technology as an intermediary between the user and the home appliance control system. Instead of direct mechanical interaction with buttons, the user's voice commands are translated into control signals through the speech recognition module, simplifying the interaction process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If various buttons and manipulators are provided for selecting functions and options, then the home appliance can provide various functions, but the device complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidmanipulator complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex system of physical buttons and manipulators from the home appliance control interface. By eliminating these mechanical components and replacing them with a microphone unit and speech recognition software, the physical device complexity is reduced while preserving all necessary control functions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent substitutes mechanical manipulators with an acoustic-based control system. The microphone unit and speech recognition algorithm replace numerous physical buttons, switches, and dials, significantly simplifying the device's physical structure while maintaining full operational capability.

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

3Adaptability or versatility

If various buttons and manipulators are provided for selecting functions and options, then the home appliance can provide various functions, but the manufacturing cost increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent removes numerous physical manipulators and buttons from the appliance, reducing the bill of materials and assembly requirements. The simplified control interface requires fewer components, leading to lower manufacturing costs while maintaining full functionality through voice-based control.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces expensive mechanical manipulator assemblies with a cost-effective acoustic sensor (microphone) and software-based speech recognition system. This substitution reduces component count, simplifies assembly processes, and lowers overall manufacturing costs while preserving all control functions.

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