Solution Overview

Problem

Existing battery boards fail to effectively contain and manage fluids discharged from energy storage devices, which can affect other components within the housing, leading to potential damage and cascading failures.

Innovation Solution

A battery board design featuring a housing with an opening enlarged portion that faces the discharge path of energy storage devices, allowing fluids to be directed outside through enlarged openings, using materials with lower melting points or thinner thicknesses to ensure rapid expansion and discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the housing is made with standard opening size, then the structural integrity is maintained, but the fluid cannot be effectively discharged and accumulates inside affecting other members

Engineering Contradiction:
Improvesystem integrityVSAvoidfluid accumulation effect
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The opening in the housing is designed to dynamically change its size from a closed state to an enlarged state in response to fluid discharge conditions. This allows the opening to adapt between maintaining structural integrity during normal operation and providing adequate discharge path when fluid accumulation occurs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The opening size parameter is changed from a fixed standard size to a variable size that can enlarge when needed. This parameter change enables the opening to provide sufficient discharge capacity for fluid while maintaining structural integrity during normal conditions.

Inventive Principle:
Principle #35Parameter changes

2Object-generated harmful factors

If the opening area is enlarged to discharge fluid, then fluid discharge capability is improved, but the housing structural strength is reduced

Engineering Contradiction:
Improvefluid discharge capabilityVSAvoidhousing strength
Core Design Contradiction:
Object-generated harmful factorsVSStrength

Solution Approach 1:

The opening structure is designed to be dynamic rather than static, allowing it to remain closed during normal operation to maintain housing strength, and only opening when fluid discharge is required. This dynamic behavior resolves the conflict between maintaining strength and providing discharge capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The housing structure is prepared in advance with the capability to open, but the actual opening action occurs only when needed. This preliminary preparation allows the structure to maintain full strength during normal operation while being ready to discharge fluid when necessary.

Inventive Principle:
Principle #10Preliminary action

3Object-affected harmful factors

If a closed housing structure is used, then protection of internal components is improved, but fluid discharge is blocked and causes damage to other members

Engineering Contradiction:
Improvecomponent protectionVSAvoidfluid discharge blockage
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The housing transitions from a completely closed structure to a dynamically controllable structure with an opening that can open and close as needed. This allows the housing to provide protection during normal operation while enabling fluid discharge when required, resolving the contradiction between protection and discharge capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The opening structure acts as an intermediary between the closed housing and the external environment, allowing controlled fluid discharge while maintaining overall housing integrity and protection of internal components.

Inventive Principle:
Principle #24Intermediary (Mediator)
