Solution Overview

Problem

Current shaft clamps with collar designs cannot be flush with a flat surface when attached to cylindrical objects, leading to space inefficiency and reduced versatility.

Innovation Solution

An adjustable clamp design featuring flanges and a middle section with a recess that can constrict or expand without deforming, allowing it to attach to cylindrical objects and create a coplanar surface with a flat surface, using fasteners to secure the clamp.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a collar design is used for the shaft clamp, then the clamp can attach to cylindrical objects, but the clamp cannot be flush with a flat surface

Engineering Contradiction:
Improveattachment capabilityVSAvoidcoplanarity with flat surface
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The clamp is divided into distinct functional segments: a collar portion for cylindrical attachment and a flange portion for flat surface mounting. This segmentation allows each part to perform its specialized function independently, resolving the contradiction between cylindrical attachment capability and coplanarity with flat surfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design transitions from a single-dimensional collar to a multi-dimensional structure incorporating flanges that extend perpendicular to the collar axis. This dimensional expansion enables the clamp to simultaneously engage with both cylindrical objects and flat surfaces in different spatial orientations.

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

2Ease of operation

If a collar design is used for the shaft clamp, then the clamp can attach to cylindrical objects, but it takes up excessive space

Engineering Contradiction:
Improveattachment capabilityVSAvoidspace occupation
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

By segmenting the clamp into a compact collar and integrated flanges, the design eliminates the need for separate mounting components. This segmentation achieves space efficiency by consolidating multiple functions into a single compact unit that attaches to cylindrical objects while maintaining a low profile.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The collar and flange structures are merged into a single integrated component rather than separate parts. This merging reduces the overall volume and eliminates gaps between components, allowing the clamp to occupy minimal space while maintaining both cylindrical attachment and flat surface mounting capabilities.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a collar design is used for the shaft clamp, then the clamp can attach to cylindrical objects, but the versatility of the clamp is limited

Engineering Contradiction:
Improveattachment capabilityVSAvoidfunctional versatility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The clamp design incorporates multiple functional elements within a single structure: the collar provides cylindrical attachment, while the flanges enable flat surface mounting and various mounting orientations. This multi-functionality allows the same clamp to serve multiple purposes including hooks, attachment mounts, and dividers, significantly enhancing versatility.

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

Solution Approach 2:

The clamp design allows for dynamic adjustment of mounting orientation and configuration through its flange structure. The ability to mount in different orientations and configurations provides adaptability to various application scenarios, transforming a static single-purpose component into a dynamic multi-purpose tool.

Inventive Principle:
Principle #15Dynamics
