Solution Overview

Problem

Professionals in various trades face the inconvenience of needing multiple types of clamps for different applications, as existing clamps are specialized for specific functions and lack versatility.

Innovation Solution

A clamping device with a rectilinear bar, a fixed jack, and a slider that can adopt straight or inclined positions, featuring a removable plate and pivoting arm to function as a carpenter's, mason's, or formwork clamp, with adjustable angular positions and a clamping head design that includes a threaded spindle for enhanced versatility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple specialized clamps are used for different trades, then each clamp can be optimized for its specific function, but the user must carry and manage multiple tools

Engineering Contradiction:
ImproveversatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamp device is designed with a fixed jack having an arm that can pivot between a straight position (for formwork clamp function) and an inclined position (for carpenter's or mason's clamp function). The slider can accommodate different clamping heads including a formwork clamping head with plate and a screw clamping head with threaded spindle, allowing a single device to perform multiple clamp functions previously requiring separate specialized tools

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The arm of the fixed jack is designed to be movable relative to the jack body, allowing it to pivot between different angular positions. This dynamic configuration enables the same clamp device to adapt its geometry for different applications - straight position for formwork clamping and inclined position for carpenter's or mason's clamp operations

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a single clamp device is designed to perform multiple functions, then versatility is improved, but the device structure becomes more complex

Engineering Contradiction:
ImproveversatilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamp device is divided into modular components: a fixed jack with a movable arm, a slider, and interchangeable clamping heads. The arm can be positioned at different angles, and the slider can accept different types of clamping heads (formwork head with plate or screw head with threaded spindle), allowing functional versatility through modular segmentation rather than a completely complex integrated design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The slider is designed to nest different types of clamping heads, with the formwork clamping head featuring a plate that can be mounted on the slider, and the screw clamping head with threaded spindle that can also be mounted on the slider. This nesting approach allows multiple clamping configurations within a single slider component, reducing overall structural complexity while maintaining versatility

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The present invention relates to a clamping device of the clamping type comprising a straight bar (2), a fixed jaw (3) integral with the bar and extending in a general direction (X) perpendicular to the bar, and a slide (4) adapted to slide along the bar (2), characterized in that the fixed jaw (3) comprises an arm (5) adapted to adopt a straight position in a straight line along the general direction X of the fixed jaw or at least a position inclined with respect to the axis X in the direction of the slide (4). This device makes it possible to combine three clamps in one, namely the carpenter's clamp, the mason's clamp, and the formwork clamp.
