Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing log splitter systems with integrally joined wedge and frame compromise the strength of the splitter head, as they require hollow wedges for interchangeability, which reduces their mechanical integrity.

Innovation Solution

A log splitter system featuring a removable splitter head with a post positioned within a socket, allowing for interchangeable wedges that can be fabricated from solid components, enhancing structural integrity and enabling different configurations for various wood sizes and splitting tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wedge is made hollow to enable interchangeability, then the adaptability for different wood sizes and splitting tasks is improved, but the structural strength and mechanical integrity of the splitter head deteriorates

Engineering Contradiction:

Improveadaptability for different wood sizes and splitting tasksVSAvoidstructural strength and mechanical integrity

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The splitter head is divided into separate components: a hollow post that receives the wedge and a separate wedge component. The post is segmented to accommodate different wedge configurations while maintaining overall structural integrity through its hollow design that can be reinforced internally.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wedge is nested within the hollow post structure, allowing the wedge to be inserted and secured inside the post. This nesting arrangement enables the wedge to be held securely while allowing the post to maintain its hollow configuration for strength and interchangeability.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Strength

If the wedge is integrally joined to the frame, then the structural strength is improved, but the versatility for different splitting configurations deteriorates

Engineering Contradiction:

Improvestructural strengthVSAvoidversatility for different splitting configurations

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The system is segmented into a frame structure, a removable post, and interchangeable wedge components. This segmentation allows the frame to maintain integral strength while the post and wedge can be changed to provide different splitting configurations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The splitter head components are made dynamic and interchangeable rather than fixed. The post can be removed and replaced, and different wedge configurations can be installed, allowing the system to adapt to different splitting tasks while the frame remains structurally integral.

Inventive Principle:

Principle #15Dynamics
