Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If experimental methods are used to find candidate electrolyte materials, then the materials can be tested for performance, but the process is time-consuming and resource-intensive

Engineering Contradiction:
Improvebattery service lifeVSAvoidmaterial screening time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-calculating and storing key parameters (electron affinity, ionization energy, HOMO/LUMO levels) of organic substances in a database before actual battery assembly. This allows the screening system to quickly evaluate candidate materials against oxygen radical interaction criteria without performing time-consuming experiments for each candidate, thus resolving the contradiction between reliable material selection and time consumption.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses computational modeling to create virtual representations of electrolyte materials and their interactions with oxygen radicals. By simulating electron transfer processes and calculating interaction energies in silico, the system identifies promising candidates before physical experimentation, reducing the need for repetitive experimental trials and accelerating the material discovery process.

Inventive Principle:
Principle #26Copying

2Reliability

If comprehensive experimental testing is conducted to address oxygen radical deterioration, then battery service life can be improved, but the effort and resources required increase significantly

Engineering Contradiction:
Improvebattery service lifeVSAvoidmaterial development efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent transforms the material screening process from experimental parameter measurement to computational parameter calculation. By changing the approach from physical testing to in-silico calculation of electron affinity, ionization energy, and interaction energy parameters, the system maintains reliable material selection while dramatically improving development efficiency and reducing resource consumption.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical/experimental system of material testing with a computational information processing system. Instead of physically assembling and testing batteries with different electrolyte candidates, the system uses computer-based calculations to predict material performance, substituting experimental mechanics with computational physics and chemistry.

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

3Productivity

If existing electrolyte materials are used, then the battery can operate, but deterioration from oxygen radicals reduces service life

Engineering Contradiction:
Improvebattery operationVSAvoidbattery service life
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary anti-action by identifying and selecting electrolyte materials with high interaction energy with oxygen radicals before battery assembly. The system pre-calculates which organic substances will effectively neutralize oxygen radicals through electron transfer, and selects these materials in advance to prevent deterioration, rather than addressing the problem after battery degradation occurs.

Inventive Principle:
Principle #9Preliminary anti-action
