Solution Overview

Problem

Existing fastener systems for perforated boards have a limited scope of applications and fail to provide an adequate solution for a broad range of uses, as they are primarily designed for hanging tools and accessories with limited versatility.

Innovation Solution

An interchangeable fastener system comprising a main fastener with counterbored holes and push grommets for attachment to perforated boards, along with an attachment member featuring ramp surfaces and mechanical stops for secure engagement, allowing for various attachment options such as clamps, hooks, and magnetic members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional fasteners are used for perforated boards, then they can hang tools and accessories, but they have limited scope of applications and lack versatility

Engineering Contradiction:

Improvescope of applicationsVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The main fastener body serves as a universal base that can accommodate multiple different attachment members (clamps, hooks, magnetic members, etc.), allowing a single fastener system to perform various functions across different applications rather than requiring separate fasteners for each purpose

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fastener system is divided into two independent components: a permanent main fastener body mounted on the perforated board, and interchangeable attachment members that can be selectively attached and detached, enabling versatility without requiring complex integrated designs

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If attachment members are made interchangeable and rotatable, then versatility and ease of detachment improve, but control over rotation and positioning becomes challenging

Engineering Contradiction:

Improveease of detachmentVSAvoidcontrol over rotation

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The attachment member incorporates a rotatable insertion member that can dynamically change orientation, allowing users to easily adjust and detach attachments while the system maintains control through mechanical stops that define valid positioning limits

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The channel acts as an intermediary structure that guides the insertion member's rotation and movement, while mechanical stops serve as intermediaries to prevent over-rotation and ensure reliable positioning without restricting necessary motion

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the insertion member allows free rotation, then ease of attachment and detachment improve, but over-rotation may occur causing misalignment or damage

Engineering Contradiction:

Improveease of attachmentVSAvoidover-rotation damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Mechanical stops are built into the channel structure to preemptively prevent over-rotation of the insertion member before misalignment or damage can occur, while still allowing sufficient rotation range for easy attachment and detachment operations

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

An interchangeable fastener system for use in combination with a perforated board or other surface on a vertical plane includes a main fastener including a base for supporting the main fastener on the perforated board; the base surrounding a channel defined by inner surfaces including opposing ramp surfaces to facilitate tightening of an attachment member, and a mechanical stop adjacent each ramp surface to prevent over rotation of the attachment member; and the attachment member including an insertion member having a first end tab and a second end tab, wherein the insertion member is sized and configured for selective passage through the channel from the front surface and wherein the attachment member may be selectively rotated until a male detent mates with a female detent for securing the attachment member to the main fastener.
