Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vise faceplates require time-consuming orientation for keyhole connections, leading to inefficiencies in faceplate exchange.

Innovation Solution

A reversible face plate design with keyhole bores and slots accessible from both the front and back, allowing for quick orientation and secure bolt tightening without needing to align the faceplate specifically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a keyhole connection is used to enable quick changing of faceplates, then the faceplate exchange speed is improved, but time is lost during orientation of the face plate

Engineering Contradiction:

Improvefaceplate exchange speedVSAvoidorientation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The keyhole slot is designed with an asymmetric recess that is completely enclosed within the periphery of the plate. This asymmetric geometry allows the bolt head to be inserted from either the front or back of the plate and automatically orient itself correctly within the enclosed recess, eliminating the need for manual orientation of the faceplate while maintaining quick exchange capability

Inventive Principle:

Principle #4Asymmetry

2Reliability

If a keyhole connection requires specific orientation for bolt insertion, then the connection reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improveconnection reliabilityVSAvoidfaceplate installation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of requiring the operator to orient the faceplate in a specific direction before bolt insertion, the design allows bolt insertion from either the front or back of the plate. The enclosed recess automatically ensures correct orientation of the bolt head, inverting the traditional approach where the operator must manually align the component before installation

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of manufacture

If the keyhole slot allows bolt insertion from one side only, then the manufacturing complexity is reduced, but the device complexity increases due to orientation requirements

Engineering Contradiction:

Improvekeyhole slot manufacturing easeVSAvoidorientation requirement complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The keyhole slot with enclosed recess is designed to accept bolt insertion from either the front or back of the plate, making the connection mechanism universal. This multi-functional design allows the same slot structure to serve multiple insertion directions without requiring different slot configurations, maintaining manufacturing simplicity while reducing operational complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)
