Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If only internal memory is used to store diagnosis codes and battery state information, then the device complexity is reduced, but the reliability deteriorates due to potential data loss from memory damage

Engineering Contradiction:
Improvedevice complexityVSAvoidreliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent introduces an external server as an intermediary to store backup diagnosis codes and battery state information. The server acts as a mediator between multiple diagnosing apparatuses and provides centralized data storage, eliminating the need for each apparatus to maintain complex local backup systems while ensuring data reliability through remote storage.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent merges the storage function of diagnosis data from multiple individual apparatuses into a centralized server. By combining storage resources and data management at the server level, the system reduces overall device complexity while improving reliability through redundant storage and centralized access.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If the diagnosis table is not updated, then the device complexity is reduced, but the measurement precision deteriorates leading to misdiagnosis

Engineering Contradiction:
Improvedevice complexityVSAvoidmeasurement precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent implements a feedback mechanism where the server receives diagnosis results from apparatuses, validates them against the updated diagnosis table, and returns corrections when misdiagnosis is detected. This feedback loop ensures measurement precision is maintained without requiring each apparatus to independently manage complex update protocols.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The server performs preliminary validation of diagnosis codes against the diagnosis table before returning results to apparatuses. By pre-checking and validating data centrally, the system ensures measurement precision without adding complexity to individual apparatuses, as the validation logic resides in the server.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If diagnosis data is not backed up externally, then the device complexity is reduced, but the loss of information increases in case of apparatus damage

Engineering Contradiction:
Improvedevice complexityVSAvoidloss of information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The server serves as an intermediary backup storage system, receiving and storing diagnosis codes and battery state information from multiple apparatuses. This external intermediary prevents information loss when individual apparatuses are damaged, while avoiding the need for each apparatus to implement complex local backup solutions.

Inventive Principle:
Principle #24Intermediary (Mediator)
