Solution Overview

Problem

Existing coolers lack easy and efficient methods for attaching and detaching batteries, which can lead to inconvenience and potential damage to the battery compartment and cooling unit components.

Innovation Solution

A cooler design with detachable battery mounts located above the compressor and condenser allows for easy attachment and detachment of power tool batteries, ensuring secure fastening and protection of the battery compartment and cooling unit components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the battery is made detachable for easy replacement, then the ease of operation is improved, but the reliability may worsen due to potential damage to the battery compartment and cooling unit components

Engineering Contradiction:
Improveease of battery replacementVSAvoidrisk of damage to components
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A battery mounting structure serves as an intermediary component between the battery and the cooling unit. This mounting structure includes a battery receiving space with fastening mechanisms that securely hold the battery in place while allowing for easy attachment and detachment, thereby preventing direct contact that could cause damage to the cooling unit components

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the battery mount is positioned above the compressor and condenser, then the ease of operation is improved for battery attachment, but the device complexity increases

Engineering Contradiction:
Improveease of battery attachmentVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cooler is divided into distinct functional modules: a cooling unit section containing the compressor and condenser, and a separate battery mounting section positioned above the cooling unit. This segmentation allows the battery to be independently attached and detached without affecting the cooling components, simplifying the overall attachment process while maintaining clear functional separation

Inventive Principle:
Principle #1Segmentation
