Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple tightening elements are used to achieve a proper seal, then the sealing reliability is improved, but the device complexity and time consumption increase

Engineering Contradiction:
Improvesealing reliabilityVSAvoidnumber of tightening elements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The clamp members are divided into two separate pieces that can be assembled around the pipe, allowing the stiffening element to be positioned between them. This segmentation enables the stiffening element to distribute compressive forces effectively while reducing the total number of tightening elements needed from four to two.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A stiffening element is introduced as an intermediary component between the clamp members and the pipe. This stiffening element has a C-shaped cross-section that provides structural support and distributes the compressive force from the tightening elements along the entire length of the clamp, eliminating the need for additional tightening elements between the ends.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple tightening elements are used to achieve a proper seal, then the sealing reliability is improved, but the operation time increases

Engineering Contradiction:
Improvesealing reliabilityVSAvoidtightening operation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The stiffening element is extracted as a separate, pre-formed component with a C-shaped cross-section. This extracted component is then positioned between the clamp members, allowing the tightening operation to be performed with only two tightening elements instead of four, significantly reducing the time required for installation while maintaining sealing reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The stiffening element is prepared in advance with its C-shaped cross-section and positioning features before the clamp assembly is put together. This preliminary preparation allows for quick installation and positioning during the tightening operation, reducing the overall time required to achieve a proper seal.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If additional tightening elements are used between clamp ends, then the sealing uniformity is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvesealing uniformityVSAvoidtightening operation ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The stiffening element provides localized structural support at critical positions along the clamp length, with its C-shaped cross-section designed to distribute compressive forces uniformly. This local reinforcement ensures sealing uniformity without requiring additional tightening elements, maintaining ease of operation.

Inventive Principle:
Principle #3Local quality

AI summary

A pipe clamp assembly (10) includes a band (12) having an inner annular seal element (14) wrappable around a pipe, opposing clamp members (16) extending from the band, and tightening elements (18) for clamping together the clamp members. The tightening elements are positioned at or near opposite ends of each of the clamp members. A stiffening element is constructed of an elongate beam with mounting holes near opposite ends of the beam. The tightening elements pass through the mounting holes of the stiffening element. There are no tightening elements along a length of the stiffening element between the mounting holes.
