Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional manual installation methods are used for electronic modules, then installation can be completed with basic tools, but installation time is excessive and labor costs are high

Engineering Contradiction:
Improveinstallation speedVSAvoidinstallation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The electronic module is designed with self-aligning features including alignment pins that automatically guide the module into the correct position on the base frame, and self-connecting electrical contacts that automatically engage with connector terminals. This eliminates the need for complex alignment tools and manual connection procedures, enabling rapid automated installation while maintaining simplicity in the installation system.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The electrical connectors and mounting features are pre-positioned and pre-configured on the electronic module housing before installation. The module includes pre-attached electrical contacts and alignment features that are ready for immediate engagement, eliminating the need for on-site wiring and alignment adjustments during the installation process.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If multiple wire cables are connected to electronic modules, then complete electrical connectivity is achieved, but installation complexity and time consumption increase significantly

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidwire connection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple individual wire connections are merged into a single integrated electrical connector assembly. The connector includes multiple contacts and terminals arranged in a compact configuration that establishes all necessary electrical connections simultaneously through a single engagement action, rather than requiring separate connections for each wire.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electrical connection system is segmented into modular components including the electronic module with integrated contacts, the base frame with connector housing, and terminal elements. This modular segmentation allows for standardized interfaces and simplified assembly, where each segment is designed to engage with others in a predetermined sequence without complex wiring procedures.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If electronic modules are securely mounted to resist vibration, then mechanical stability is improved, but heat dissipation capability may be compromised

Engineering Contradiction:
Improvevibration resistanceVSAvoidheat dissipation
Core Design Contradiction:
Stability of the object's compositionVSTemperature

Solution Approach 1:

The mounting system provides different local qualities at different contact points: rigid mounting feet and alignment pins provide mechanical stability and vibration resistance at the mounting interface, while dedicated heat sink elements and thermal pathways provide heat dissipation at the thermal interface. This localized differentiation allows simultaneous optimization of both vibration resistance and heat dissipation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Thermal interface materials and heat transfer compounds are introduced as intermediaries between the electronic module housing and the base frame heat sink surfaces. These intermediary materials enhance thermal conductivity while maintaining mechanical contact stability, facilitating effective heat transfer without compromising the rigid mechanical connection needed for vibration resistance.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Extent of automation

If automated robotic installation is implemented, then installation speed and cost efficiency increase, but precise alignment and securing mechanisms are required

Engineering Contradiction:
Improverobotic installation capabilityVSAvoidalignment precision
Core Design Contradiction:
Extent of automationVSManufacturing precision

Solution Approach 1:

The electronic module incorporates self-aligning features such as protrusion-alignment pin pairs and self-centering connector interfaces that automatically guide the module into precise position during robotic installation. These features eliminate the need for complex robotic positioning systems and sensors, allowing standard automated handlers to achieve precise alignment through the module's inherent mechanical guidance features.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mounting system includes compliance elements such as spring-loaded mounting feet and flexible connector terminals that accommodate minor positioning variations and tolerances. These beforehand cushioning features ensure reliable mechanical and electrical connections even when robotic placement precision varies within normal tolerances, preventing installation failures without requiring ultra-precise robotic positioning.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
