Solution Overview

Problem

Existing battery pack configurations lack versatility and ease of integration with electronic circuitry, particularly when building custom battery packs using 18650 and 26650 lithium cells, as they do not efficiently accommodate auxiliary structures or allow for secure attachment of components.

Innovation Solution

The use of battery spacer nuts and spacers with dovetail pins and slots enables various configurations, allowing for the secure attachment of circuit boards and other components, and accommodating different materials, including metal, plastic, and wood, through bolts and washers, providing a sturdy and adaptable framework for battery packs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional battery pack configurations are used, then the structure is simple, but the versatility and ease of integration with electronic circuitry is poor

Engineering Contradiction:

Improveversatility and ease of integrationVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spacer nut is designed with multiple functions: it provides spacing between battery cells, serves as a mounting structure for electronic circuitry via integrated threaded holes, and enables modular assembly through standardized dimensions. This multi-functionality resolves the contradiction by increasing versatility without proportionally increasing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the spacing function and the mounting function into a single integrated component. The spacer nut combines the mechanical spacing role with the electrical mounting role, allowing both battery cell separation and circuit board attachment to be achieved through one component rather than multiple separate parts

Inventive Principle:

Principle #5Merging (Combining)

2Ease of operation

If battery spacer nuts with integrated mounting features are used, then the ease of attachment of electronic circuitry is improved, but the device complexity increases

Engineering Contradiction:

Improveease of attachmentVSAvoidcomponent complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The spacer nut includes integrated threaded holes that serve as self-contained mounting features, eliminating the need for separate mounting brackets or additional fastening components. The component serves itself by providing both spacing and mounting capabilities, improving ease of attachment while keeping the overall system simple

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If modular spacer nut configurations are used, then the adaptability for different battery pack designs is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improveadaptability for different configurationsVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The battery pack structure is segmented into modular units using standardized spacer nuts that can be independently manufactured and then assembled in various configurations. This segmentation allows different battery pack designs to be created from the same basic components, improving adaptability while maintaining manufacturing simplicity through standardization

Inventive Principle:

Principle #1Segmentation
