Solution Overview

Problem

Existing pressing tools with fiber composite materials suffer from impaired connections between pressing levers and jaws during the pressing process, leading to inconsistent compression quality and wear issues.

Innovation Solution

A pressing lever arrangement featuring a pressing lever with a receptacle and a pressing jaw connected via a securing element, preventing relative displacement, utilizing tempered steel for the lever and case-hardened steel for the jaw, with securing elements like pins, elevations, and material connections to ensure stable and wear-resistant performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the press jaw is firmly connected to the press lever during curing, then the connection is strong, but the connection can be impaired during the pressing process

Engineering Contradiction:
Improveconnection strengthVSAvoidconnection reliability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The connection system is segmented into multiple independent locking elements (at least one locking element) that distribute the locking function across several points, preventing single-point failure and maintaining reliable connection throughout the pressing process

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking elements are pre-installed and configured to engage the press jaw with the press lever before the pressing operation begins, ensuring the connection is established and secured in advance to prevent impairment during use

Inventive Principle:
Principle #10Preliminary action

2Weight of moving object

If the press jaw and press lever are made of composite material, then weight is reduced, but wear resistance deteriorates

Engineering Contradiction:
Improvepress lever weightVSAvoidwear resistance
Core Design Contradiction:
Weight of moving objectVSReliability

Solution Approach 1:

The solution uses composite construction by combining different materials - the press lever and press jaw are made from material combinations that optimize both weight and wear resistance properties, rather than using a single material for both components

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If the press jaw is firmly connected to the press lever, then positioning is stable, but displacement prevention is insufficient

Engineering Contradiction:
Improvepositioning stabilityVSAvoiddisplacement prevention
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The locking elements extend in multiple directions and dimensions to constrain the press jaw against the press lever, preventing displacement not only along the pressing axis but also in lateral directions, adding dimensional constraints to the connection

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