Solution Overview

Problem

Existing nail setting devices face downtime due to limited nail magazine capacity, requiring frequent magazine replacements and disrupting continuous production, especially in automated systems where a large number of nails need to be sequentially driven into components.

Innovation Solution

A feed device with a hose line connecting a remote supply unit to the nail setting tool, using an ejector pump for continuous nail feeding, and a buffer section to ensure uninterrupted operation, allowing nails to be transported and fed over a longer distance, and a switchable diverter for seamless supply unit switching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If nails are stored in a magazine attached to the nail-setting device, then nails can be fed quickly to the device, but the magazine capacity is limited requiring frequent replacements and causing downtime

Engineering Contradiction:
Improvecontinuous operation timeVSAvoidnail storage capacity
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The invention transitions from local storage (magazine attached to nail-setting device) to remote storage (supply unit located away from the device), using a hose line to bridge the spatial gap. This dimensional change in storage location enables significantly larger nail storage capacity while maintaining quick feeding capability through the flexible hose connection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The hose line acts as an intermediary element connecting the remote supply unit to the nail-setting device. This mediator enables nail transport over longer distances and allows the system to overcome the limitation of attached magazines by providing a flexible connection that maintains feeding efficiency while enabling remote, high-capacity storage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If a magazine with large nail capacity is used, then fewer replacements are needed, but the magazine becomes bulky and difficult to handle and replace

Engineering Contradiction:
Improvedowntime for magazine replacementVSAvoidmagazine handling ease
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The invention extracts the large-capacity storage function from the nail-setting device itself and places it in a separate, stationary supply unit. This separation allows the magazine to be large and stationary (optimizing capacity) while the mobile component becomes the small nail-setting device with hose connection (optimizing handling ease).

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

By relocating storage to a different spatial dimension (remote stationary location vs. attached portable location), the system achieves large capacity without compromising the portability and ease of handling of the nail-setting device.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If nails are transported over a longer distance to the nail-setting device, then continuous feeding is enabled, but reliable transport over longer distances becomes more difficult

Engineering Contradiction:
Improvecontinuous nail feeding capabilityVSAvoidnail transport reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The hose line, as a flexible conduit, enables reliable nail transport over longer distances by providing a flexible, adaptable connection that can accommodate movement and positioning variations. The flexibility of the hose maintains feeding reliability while enabling extended transport distance.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The hose line serves as an intermediary that bridges the gap between remote storage and the nail-setting device, enabling continuous feeding over longer distances while maintaining transport reliability through its flexible, adaptable connection.

Inventive Principle:
Principle #24Intermediary (Mediator)
