Solution Overview

Problem

Existing saddles for anchoring and supporting pipes often slide relative to hangers due to their design, which can lead to instability and moisture accumulation, and lack sufficient strengthening force.

Innovation Solution

The development of arcuate saddles with partial ribs on the lower face that inhibit sliding and provide additional strength, featuring closed ends and a flush fit with hangers and pipes to prevent moisture accumulation, manufactured using die and roll bending processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional flat saddles or saddles with 180° arcuate ribs are used, then the saddle structure is simple and easy to manufacture, but the saddle slides relative to the hanger and lacks sufficient strengthening force

Engineering Contradiction:

Improvestrengthening forceVSAvoidsaddle structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent applies local quality by adding ribs only to specific portions of the saddle structure rather than the entire saddle. The ribs are positioned at strategic locations to provide strengthening force and prevent sliding, while the rest of the saddle maintains its simple flat or arcuate design. This localized addition of structural elements improves strength without significantly increasing overall device complexity.

Inventive Principle:

Principle #3Local quality

2Reliability

If the saddle has a simple flat design, then it is easy to manufacture, but it allows sliding relative to the hanger and moisture accumulation

Engineering Contradiction:

Improveanti-sliding capabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies segmentation by dividing the saddle surface into distinct regions with and without ribs. The ribs are segmented structural elements that are integrated into specific portions of the saddle. This segmentation allows the saddle to maintain manufacturing simplicity in most areas while incorporating anti-sliding features in localized regions, thus improving reliability without significantly complicating the manufacturing process.

Inventive Principle:

Principle #1Segmentation

3Strength

If partial ribs are added to the saddle, then sliding is inhibited and strength is increased, but the manufacturing process becomes more complex

Engineering Contradiction:

Improvestructural integrityVSAvoidmanufacturing process

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent applies merging by integrating the ribs directly into the saddle manufacturing process rather than adding them as separate components. The ribs are formed as integral parts of the saddle structure during the same manufacturing operation, combining multiple functions (structural support, anti-sliding) into a single unified component. This reduces the number of manufacturing steps and assembly operations, thereby minimizing the increase in manufacturing complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Embodiments of the present invention relate to arcuate saddles with partial ribs typically used to anchor and suspend insulated or non-insulated pipes. Partial ribs on the lower face of the saddle inhibit the saddle from sliding relative to the hanger when engaged and provide strengthening force to the saddle.
