Solution Overview

Problem

Existing outdoor power equipment packaging and storage solutions are inefficient, taking up significant space and lacking integrated charging capabilities, especially for lawn maintenance devices.

Innovation Solution

A case assembly with a top and bottom portion that encloses the equipment, allowing wheel protrusion for mobility, a foldable handle, and integrated charging and storage compartments, facilitating compact storage and transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If outdoor power equipment is stored in fully assembled form, then the equipment is ready for immediate use, but it takes up significant amount of floorspace

Engineering Contradiction:
Improvereadiness for useVSAvoidfloorspace
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The equipment is divided into separable components that can be stored in a compact, disassembled state within the case, eliminating the need to store the entire assembled machine and significantly reducing floorspace requirements

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The case is designed to nest the equipment components within each other and within the case structure itself, allowing the equipment to occupy minimal storage space while maintaining readiness for assembly and use

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If traditional packaging is used for shipping and storage, then the equipment is protected during transport, but the packaging is disposed of after use and does not provide long-term storage solution

Engineering Contradiction:
Improveprotection during transportVSAvoidlong-term storage capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The case serves multiple functions: it provides protective packaging during shipping, serves as a compact storage container when the equipment is not in use, and enables portable transportation by allowing the equipment to be rolled within the case, replacing the need for separate packaging and storage solutions

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

Solution Approach 2:

The invention replaces disposable packaging with a durable, reusable case that maintains protection capabilities throughout the equipment's lifecycle, eliminating the need to discard packaging after initial shipping

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Area of stationary object

If the equipment is stored in a compact form, then storage space is reduced, but the equipment lacks integrated charging capabilities and requires separate charging setup

Engineering Contradiction:
Improvestorage spaceVSAvoidcharging infrastructure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The charging dock and battery charging capability are integrated directly into the case structure, combining the storage function with the charging function in a single unified system, eliminating the need for separate charging equipment and reducing overall system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The equipment automatically charges when placed in the case with the battery dock engaged, requiring no manual intervention or separate charging setup, and the case provides the charging infrastructure as an inherent feature rather than an add-on

Inventive Principle:
Principle #25Self-service
