Solution Overview

Problem

Existing battery cell assemblies lack a housing mechanism that allows for easy enclosure of battery cells, posing a challenge in design and assembly.

Innovation Solution

The use of rectangular ring-shaped panels with coupling members and ledges to securely hold battery cells between them, facilitated by a method that involves coupling these panels together with gaskets to fix the cells in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional housing mechanisms are used for battery cells, then structural strength is maintained, but assembly ease deteriorates

Engineering Contradiction:
Improveassembly easeVSAvoidhousing mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The housing is divided into multiple panel members that can be separately assembled. Each panel member is a discrete component that can be independently manufactured and positioned, allowing for easier assembly compared to a monolithic housing structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The battery cell is enclosed within a housing formed by nested panel members. The panels are arranged in a layered configuration where inner panels contain the cell and outer panels provide structural support, creating a nested arrangement that simplifies assembly.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If battery cells are securely enclosed in housing, then reliability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvecell enclosure reliabilityVSAvoidmanufacturing ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The enclosure is segmented into multiple panel members that can be manufactured independently using standard fabrication processes. This segmentation allows each panel to be produced separately and then assembled, improving manufacturing ease while maintaining reliable enclosure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The panel members serve multiple functions: they provide structural support, create the enclosing housing, and facilitate assembly through standardized coupling mechanisms. This multi-functionality reduces the number of separate components needed, simplifying manufacturing.

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

3Stability of the object's composition

If coupling members and ledges are added to hold cells, then cell fixation is improved, but device complexity increases

Engineering Contradiction:
Improvecell fixation stabilityVSAvoidhousing structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The coupling members and ledges are integrated directly into the panel members themselves rather than being separate components. The ledges are formed as part of the panel structure, and coupling members are attached to or formed with the panels, merging multiple functions into unified elements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The panel members are designed to self-align and self-secure during assembly. The ledges and coupling members are configured so that when panels are brought together, they automatically engage and fix the battery cell in place without requiring additional fastening operations or complex adjustment mechanisms.

Inventive Principle:
Principle #25Self-service
