Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a battery is integrated into a memory device using additional manufacturing steps on another part of the substrate, then energy storage functionality is added, but the device complexity and manufacturing process complexity increase

Engineering Contradiction:
Improveenergy storage functionalityVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the memory cell structure with the battery structure by using the same electrodes and electrolyte layer for both information storage and energy storage functions. The first electrode, second electrode, and electrolyte layer are shared between the memory point and the energy storage zone, eliminating the need for separate battery manufacturing steps and reducing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electrodes and electrolyte layer serve dual purposes: they enable both information storage (through resistive switching in the memory point) and energy storage (through electrochemical reactions in the energy storage zone). This multi-functionality allows a single structure to fulfill multiple roles, simplifying the overall device architecture and manufacturing process.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If only a part of the memory cell surface is used for information storage, then information storage functionality is achieved, but the surface area utilization is inefficient

Engineering Contradiction:
Improvesurface area utilizationVSAvoidunused surface area
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The entire memory cell surface is utilized by implementing multi-functionality: the same electrodes and electrolyte layer serve both information storage and energy storage purposes. The first electrode, second electrode, and electrolyte layer are used in both the memory point and the energy storage zone, ensuring complete surface utilization without wasted areas.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent transitions from single-function vertical structures to multi-functional structures by adding the energy storage dimension alongside the information storage function. This allows the same physical space to serve multiple purposes, effectively doubling the functional capacity of each memory cell without increasing surface area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Use of energy by moving object

If external batteries are used to supply energy to memory devices, then energy supply is ensured, but the device complexity and external component requirements increase

Engineering Contradiction:

Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent combines the energy storage function directly into the memory cell structure by integrating an energy storage zone using the same electrodes and electrolyte layer. This eliminates the need for external batteries and their associated connection components, reducing device complexity while ensuring continuous energy supply for memory operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The memory device becomes self-sufficient by incorporating an internal energy storage zone that supplies power directly to the memory point. The integrated battery structure eliminates dependence on external power sources, allowing the device to service its own energy needs without additional external components or complex power management systems.

Inventive Principle:
Principle #25Self-service
