Solution Overview

Problem

Current clamping methods, such as using a G-clamp for turbochargers and exhaust pipes, require two people and are labor-intensive and expensive due to the need for manual positioning and engagement.

Innovation Solution

A clamping device with resilient biasing means, such as springs, that automatically moves to a clamped position when fitted, allowing single-user operation, and includes mounting means for secure placement before actuation, reducing the need for manual alignment and engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual positioning and engagement method is used, then clamping operation can be performed, but it requires two people and is labor-intensive

Engineering Contradiction:
Improveclamping operationVSAvoidlabor efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The clamping device is designed to automatically move from unclamped to clamped position through resilient biasing means (springs) that self-actuate when the mounting means is removed. This eliminates the need for manual positioning and engagement by a second person, allowing single-user operation while maintaining clamping functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device is pre-configured with resilient biasing means that store potential energy in a ready state. When the mounting means is removed, the pre-loaded springs automatically generate the clamping force, performing the clamping action without requiring manual intervention during the actual clamping operation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual positioning and engagement is required, then proper clamping can be achieved, but the process is expensive due to labor costs

Engineering Contradiction:
Improveclamping accuracyVSAvoidoperational cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The automatic self-actuating mechanism ensures consistent and reliable clamping engagement without manual intervention. The resilient biasing means automatically positions the clamping members onto the articles, providing repeatable and accurate clamping action while eliminating the need for a second operator, thereby reducing labor costs.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention replaces the manual mechanical engagement system with an automated spring-driven system. The resilient biasing means converts stored elastic potential energy into mechanical work that automatically positions and secures the clamping members, eliminating the need for manual positioning while maintaining reliable clamping accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If automatic resilient biasing is used, then single-user operation is enabled, but additional components (springs, mounting means) are added

Engineering Contradiction:
Improveuser operationVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The clamping device is divided into distinct functional modules: resilient biasing means (springs), mounting means for temporary positioning, and clamping members. This segmentation allows the automatic actuation function to be added as a modular feature rather than requiring a complete redesign of the entire device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting means serves as a temporary positioning aid that is discarded (removed) after initial positioning. The resilient biasing means are permanently integrated and continuously provide biasing force. This approach adds only the necessary permanent components while using a temporary component that is removed after serving its positioning purpose.

Inventive Principle:
Principle #34Discarding and recovering
