Orthogonal Driver Joint Structure for Wide Staple Driving

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing driving tools face challenges in accommodating wider driven members without increasing the size of the driving nose, particularly when a release channel is formed parallel to a wide driving channel.

Innovation Solution

The driving tool incorporates a striker and engagement member joined orthogonally, with a lifter engaging sections sequentially to return the driver to its initial position, allowing a wider driven member to be used without enlarging the driving nose by displacing the release channel orthogonally to the driving channel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a release channel is formed in parallel with a wide driving channel to guide a wide driven member, then the driven member can be driven effectively, but the driving nose increases in size

Engineering Contradiction:

Improvecapability to drive wide driven membersVSAvoidsize of driving nose

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The engagement member is joined to the striker in a direction orthogonal to the longitudinal direction of the driver, displacing the release channel orthogonal to the driving channel. This dimensional reorganization allows the driving channel to be widened for wide driven members without proportionally increasing the driving nose size, as the release channel occupies a different spatial dimension.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If the engagement member is joined to the striker in the longitudinal direction of the driver, then the structure is simplified, but the release channel interferes with the driving channel when wide driven members are used

Engineering Contradiction:

Improvestructure of driverVSAvoidinterference between release channel and driving channel

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The engagement member is positioned orthogonal to the striker's longitudinal direction, placing the release channel in a different dimension from the driving channel. This eliminates interference between the two channels while maintaining structural integrity, as they operate in perpendicular planes rather than competing for the same space.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A two-member joint structure driver of a driving tool includes a striker and an engagement member. A channel to guide the striker and a release channel for the engaging section of the engagement member to pass through are shifted in a thickness direction of the driver. The width of the guide channel is expanded, and wider striker can be used without expanding the release channel. The cost of the driver can be reduced by having the two-member joint structure.
