Solution Overview

Problem

Conventional profile clamps lose shape and form under load, leading to non-uniform contact and increased manufacturing costs, and are less adaptable to thermal expansion stresses.

Innovation Solution

The clamp apparatus features integrally formed protruding means with the band, maintaining shape and form, allowing uniform contact distribution and improved load retention, with a V-shaped profile that acts like a spring under load, and is roll formed for increased strength and thermal adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If additional features are welded or formed onto the ends of the V-shaped profile, then the clamp can maintain its shape and form, but the manufacturing cost increases

Engineering Contradiction:
Improveshape and form of clampVSAvoidmanufacturing cost
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent merges the protruding means with the band by providing an integral construction where the protruding means extend from the band as a single continuous piece. This eliminates the need for separate welding or attachment operations, thereby maintaining the clamp's shape while reducing manufacturing cost and complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Force

If the clamping band is placed under load, then the clamp can perform its clamping function, but the clamping band loses its shape and form towards the lugs

Engineering Contradiction:
Improveclamping forceVSAvoidshape and form of clamping band
Core Design Contradiction:
ForceVSShape

Solution Approach 1:

The patent applies local quality by providing a V-shaped profile specifically at the protruding means while the band itself remains conventional. This localized profiling ensures uniform contact distribution at the critical clamping interface under load without requiring the entire band to maintain complex shape, thus preserving functionality while managing deformation.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If the clamp is made with conventional pressing process, then the manufacturing process is simple, but the clamp is less able to adapt to thermal expansion stresses

Engineering Contradiction:
Improvemanufacturing process simplicityVSAvoidthermal expansion adaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent utilizes the elastic properties of the material by designing the protruding means with an integral construction that allows controlled deformation. The V-shaped profile and integral design enable the clamp to flex and adapt to thermal expansion stresses through elastic deformation, transforming the material's mechanical properties into a solution for thermal adaptability while maintaining manufacturing simplicity.

Inventive Principle:
Principle #35Parameter changes
