Solution Overview

Problem

Existing garden tools lack versatility and functionality, with most being single-function and non-detachable, limiting their utility and adaptability.

Innovation Solution

A backpack tool apparatus with detachable tools connected via guide rails and grooves, allowing for interchangeable functions such as blowers, leaf suction machines, and grass cutters, with adjustable positioning and independent operation, and equipped with locking mechanisms for secure attachment and release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If tools are made detachable and interchangeable, then versatility and adaptability are improved, but device complexity increases due to multiple connection mechanisms

Engineering Contradiction:
Improvetool interchangeabilityVSAvoidconnection mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal connection interface system where the guide rail and guide groove design allows different tool types (blower, leaf suction machine, grass cutter, chain saw) to be attached to the same backpack assembly. The standardized interface enables one backpack assembly to support multiple tool functions, achieving multi-functionality without requiring separate specialized equipment for each task.

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

Solution Approach 2:

The tool system is divided into separable components: the backpack assembly (power source and control) and the detachable tool modules. This segmentation allows independent replacement of tool modules while retaining the core backpack unit, enabling versatility without permanently increasing overall system complexity.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple tools are equipped simultaneously, then productivity and working efficiency are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveworking efficiencyVSAvoidtool system configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system transitions from a static single-tool design to a dynamic multi-tool configuration where tool modules can be added, removed, or swapped based on task requirements. The backpack assembly maintains readiness to support multiple tool types simultaneously or sequentially, allowing the system to adapt its functionality dynamically rather than being fixed to one tool type.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The backpack assembly is pre-configured with universal connection interfaces (guide rails and guide grooves) and power distribution systems that are ready to accommodate various tool modules. This preliminary preparation of the interface system eliminates the need for complex customization when tools are exchanged, streamlining the productivity enhancement while controlling complexity.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If locking mechanisms are added for secure attachment, then reliability is improved, but ease of operation decreases due to additional locking and release steps

Engineering Contradiction:
Improvetool attachment securityVSAvoidtool attachment and detachment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism is designed to engage automatically when a tool module is inserted into the backpack assembly. The guide rail and guide groove geometry provides self-alignment and self-locking functionality, eliminating the need for manual locking operations. The release button provides simple one-handed operation for detachment, maintaining ease of use while ensuring secure attachment during operation.

Inventive Principle:
Principle #25Self-service
