Solution Overview

Problem

Existing implement retainers lack advanced features for improved attachment and retention of various implements, leading to limitations in versatility and security.

Innovation Solution

The assembly includes a mounting portion with a body portion and a substrate-penetrating portion, featuring an implement-retaining portion with male portions that engage with male-receiving portions and wedging passages, providing a secure and versatile attachment mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing implement retainers are used, then the basic retention function is provided, but the attachment security and versatility are limited

Engineering Contradiction:
Improveattachment securityVSAvoidimplement retention versatility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The implement retainer is divided into multiple male portions (first, second, third male portions) that can be independently positioned and engaged. Each male portion can engage with corresponding female portions on different implements, allowing the single retainer to securely hold multiple different implements simultaneously, thus improving both attachment security and versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retainer body is designed with multiple types of engagement features (multiple male portions with different configurations, male-receiving portions, wedging passages) that can accommodate various implement types. This multi-functional design allows the same retainer to securely attach different implements (e.g., snowblower augers, plows) to a single mounting portion, enhancing versatility while maintaining secure attachment.

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

2Strength

If a secure attachment mechanism is implemented, then the retention strength is improved, but the device complexity increases

Engineering Contradiction:
Improveretention strengthVSAvoidattachment mechanism complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The attachment mechanism is segmented into multiple independent male portions and female portions that can engage separately. This segmentation allows the complex retention function to be achieved through multiple simple engagement points rather than a single complex joint, distributing the retention strength across multiple locations while keeping each individual engagement feature relatively simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wedging passages are designed to automatically wedge the male portions into place when the implement is inserted. The friction-fit configuration provides self-locking action without requiring additional fasteners or complex adjustment mechanisms, achieving strong retention through the self-service wedging action of the components themselves.

Inventive Principle:
Principle #25Self-service

3Reliability

If multiple engagement features are added, then the resistance to disconnection and rotation is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improveresistance to disconnectionVSAvoidmanufacturing ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Multiple engagement features (multiple male portions, female portions, and wedging passages) are merged into a single integrated retainer body component. This consolidation allows all the engagement features to be manufactured as one piece using processes like injection molding, reducing the need for assembling multiple separate parts and simplifying manufacturing despite the increased number of engagement points.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The retainer body serves multiple functions simultaneously: it provides structural support, houses multiple engagement features, and incorporates wedging passages for automatic locking. This multi-functionality in a single component reduces the total number of parts that need to be manufactured and assembled, offsetting the complexity of having multiple engagement features.

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