Solution Overview

Problem

Conventional clamps often fail to apply consistent force across multiple directions, leading to warping or bowing of workpieces, especially when gluing, as they typically require multiple adjustments and do not evenly distribute pressure.

Innovation Solution

A bi-directional clamp system with two clamp bars and multiple clamp arms angled between 90 degrees and 150 degrees, allowing force application to four sides of a material, featuring a threaded member and clamping feet that adjust to accommodate varying thicknesses, enabling even pressure distribution without warping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If conventional clamps are used to hold workpieces, then the workpieces can be secured for gluing, but the clamps fail to apply consistent force across multiple directions, causing warping or bowing of the workpieces

Engineering Contradiction:
Improveworkpiece integrityVSAvoidworkpiece flatness
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The clamp system is divided into multiple independent clamp assemblies (at least two, preferably more) arranged in a circular or radial pattern around the workpiece. Each clamp assembly independently applies clamping force from a different direction, segmenting the overall clamping function to achieve uniform multi-directional pressure distribution and prevent workpiece warping.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from conventional single-direction or limited-direction clamping to three-dimensional multi-directional clamping. The clamp assemblies are positioned at different angular positions around the workpiece, creating a radial or circular arrangement that applies force from multiple dimensions simultaneously, ensuring uniform pressure distribution.

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

2Stress or pressure

If multiple conventional clamps are used to apply even pressure, then pressure distribution improves, but the device complexity and number of adjustments required increases

Engineering Contradiction:
Improvepressure distribution uniformityVSAvoidclamp system structure
Core Design Contradiction:
Stress or pressureVSDevice complexity

Solution Approach 1:

Multiple clamp assemblies are merged into a single integrated clamp system that functions as one unified device. The clamp bars, arms, and adjustment mechanisms are combined into a coordinated system where all components work together simultaneously to apply multi-directional pressure, reducing the need for separate individual clamp adjustments.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamp system is designed with universal applicability to accommodate various workpiece sizes and shapes. The adjustable clamp arms and reconfigurable arrangement allow the same device to effectively clamp different types of workpieces, reducing the need for multiple specialized clamp tools.

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

3Force

If conventional clamps require multiple adjustments to achieve proper clamping, then the clamping force can be adequate, but the time required for setup and operation increases

Engineering Contradiction:
Improveclamping forceVSAvoidclamp setup time
Core Design Contradiction:
ForceVSLoss of time

Solution Approach 1:

The clamp system is pre-configured with multiple clamp assemblies positioned in optimal angular arrangements around the workpiece. The adjustable arms and clamping mechanisms are preliminarily set to accommodate expected workpiece dimensions, reducing the number of adjustments needed during actual operation and enabling faster setup.

Inventive Principle:
Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system ensures constant, even pressure across all sides of the workpiece, reducing the risk of warping and allowing for efficient gluing processes by applying force from four distinct directions, thus maintaining the integrity of the material during curing.

Implementation Method 1

a threaded member, operatively connected to the handle at a first end and the clamping foot at a second end, wherein rotation of the handle in a first direction is operative to move the threaded member and thereby the clamping foot in a direction towards the material
