Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a mechanical system is used to enable engagement of plugs and receptacles for energy transfer, then automation and precision are improved, but device complexity increases

Engineering Contradiction:
Improveautomation of energy transferVSAvoidcomplexity of mechanical system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical systems with a robotic system that uses sensors, controllers, and automated positioning mechanisms. The robotic system employs visual or proximity sensors to locate the energy transfer interface, uses controlled movement mechanisms to reach and engage connectors, and relies on electronic control systems to coordinate the entire process, thereby reducing mechanical complexity while maintaining or improving automation capability.

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

Solution Approach 2:

The robotic system is designed to autonomously perform the energy transfer operation without human intervention. It independently locates the energy transfer interface through sensor systems, navigates to the correct position, engages the connectors, completes the energy transfer, and then disengages and returns to its storage position, effectively serving itself throughout the entire process.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the machine is positioned close to the mechanical system for energy transfer, then ease of operation is improved, but risk of damage from inadvertent contact increases

Engineering Contradiction:
Improvepositioning for energy transferVSAvoidrisk of damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The robotic system acts as an intermediary between the machine and the energy transfer system. It extends from a protected housing structure to reach the energy transfer interface on the machine, allowing the machine to remain at a safe distance from the housing while still enabling energy transfer. This intermediary approach eliminates the need for the machine to be positioned close to the mechanical system, thereby reducing the risk of inadvertent contact damage.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the robotic system operates in harsh environmental conditions, then adaptability is improved, but reliability decreases due to increased risk of damage

Engineering Contradiction:
Improveoperation in harsh conditionsVSAvoidsystem reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts the robotic system from the harsh external environment by housing it within a protected structure. The robotic system operates from this protected environment, extending only when needed to perform energy transfer operations. This separation allows the robotic system to maintain high reliability by avoiding exposure to harsh conditions while still being adaptable enough to operate in various external environments through controlled extension and retraction.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The housing structure provides beforehand protection for the robotic system against harsh environmental conditions such as extreme temperatures, moisture, dust, and physical impacts. By pre-establishing this protective barrier, the system ensures the robotic components remain in a controlled, benign environment, thereby maintaining reliability while retaining the capability to adapt to external harsh conditions when needed for operation.

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