Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a remote operator terminal is assigned without checking specifications, then assignment speed is improved, but remote operation accuracy deteriorates

Engineering Contradiction:
Improveassignment speedVSAvoidremote operation accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system performs preliminary action by acquiring and storing terminal specification information in advance, before the assignment process begins. This allows the assignment unit to quickly match terminals with tasks by comparing pre-stored specifications against task requirements, maintaining high assignment speed while ensuring accuracy through pre-validated specification data.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention introduces an assignment unit as an intermediary between the terminal pool and task assignments. This intermediary component specifically handles the matching logic by comparing terminal specifications with task requirements, separating the complexity of specification verification from the assignment process itself and enabling both speed and accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If terminal specification verification is implemented, then remote operation accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveremote operation accuracyVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system extracts the specification verification function as a separate, dedicated component within the assignment unit. By taking out the complexity of specification comparison and matching from the overall system flow, the verification process becomes a modular subroutine that can be executed efficiently without complicating the broader assignment architecture.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses copying by storing terminal specification information as data records that can be repeatedly queried and compared. Instead of re-evaluating physical terminal properties each time, the system copies specification data into a searchable format, allowing rapid verification without physical inspection or complex real-time sensing.

Inventive Principle:
Principle #26Copying

3Reliability

If specification-matched terminals are assigned, then operational reliability is improved, but assignment time increases

Engineering Contradiction:
Improveoperational reliabilityVSAvoidassignment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

By acquiring and storing terminal specification information in advance as pre-processed data, the system eliminates the need for real-time specification gathering during assignment. This preliminary action ensures that when assignment time comes, only fast comparison operations are needed, maintaining both reliability through complete specification verification and speed through efficient data retrieval.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The assignment unit performs partial verification by focusing only on the specific specification parameters relevant to the current task requirements, rather than checking all possible terminal attributes. This selective verification approach reduces comparison time while still ensuring sufficient operational reliability for the given task.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A remote operation system (1) of remote operation of a mobility (100), the remote operation system (1) includes one or more processors configured to: acquire terminal specification information indicating specifications of each of a plurality of remote operator terminals; acquire required capability information indicating at least a required terminal specification that is a specification required for the remote operation of a target mobility; and assign a first remote operator terminal that meets the required terminal specification out of the remote operator terminals to the remote operation of the target mobility, based on the terminal specification information and the required terminal specification.
