Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mechanical parts and electronic components are integrated in a hybrid watch movement, then the functionality and features are enhanced, but the components fail to interact synergistically

Engineering Contradiction:
Improvefunctionality integrationVSAvoidcomponent interaction
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges mechanical and electronic components into a unified hybrid movement system where the electronic control unit directly interfaces with mechanical elements through a shared circuit board architecture. This integration enables synergistic interaction between components, allowing the electronic system to control mechanical functions (such as date display, moonphase indication) while mechanical movements provide power and timekeeping functions that feed back to the electronic system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hybrid movement system is designed with multi-functional components that serve both mechanical and electronic purposes. The movement mechanism not only provides timekeeping but also powers electronic sensors and communication modules. The control unit manages multiple functions including time display, date indication, moonphase display, and wireless communication, creating a universal system where components interact across mechanical and electronic domains.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If Lavet micro-motors are integrated into the mechanical movement, then additional display functions are enabled, but electro-magnetic interference with mechanical parts occurs

Engineering Contradiction:
Improvedisplay functionalityVSAvoidelectro-magnetic interference
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces shielding structures and filtering circuits as intermediary elements between the Lavet micro-motors and the mechanical movement components. These intermediaries block or attenuate electro-magnetic fields generated by the motors, preventing interference with the sensitive mechanical parts while still allowing the motors to drive display functions such as date and moonphase indicators.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent acknowledges the electro-magnetic fields generated by Lavet micro-motors and converts this potentially harmful effect into a beneficial control mechanism. The electronic system uses controlled electro-magnetic fields from the motors to drive specific display functions, while shielding and filtering ensure that only intended electro-magnetic interactions occur, transforming the interference problem into a functional advantage.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Loss of information

If electronic sensors and wireless communication modules are added to the mechanical movement, then data transmission and monitoring capabilities are improved, but the complexity of the movement increases

Engineering Contradiction:
Improvedata transmission capabilityVSAvoidmovement structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the hybrid movement into distinct functional modules: a mechanical timekeeping module, an electronic control module with integrated circuit board, sensor modules, and wireless communication modules. Each module is independently designed and then integrated, allowing for easier manufacturing, testing, and maintenance while reducing overall system complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hybrid movement system incorporates self-monitoring capabilities where sensors detect the operational status of mechanical and electronic components, and the control unit automatically manages power distribution, data processing, and communication functions. This self-service approach reduces the need for external intervention and simplifies user interaction despite the increased internal complexity.

Inventive Principle:
Principle #25Self-service
