Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wire wrapping connection is used to connect wire cable to anchor pipe, then connection is simple to implement, but cable tightening and tensioning capability is insufficient

Engineering Contradiction:
Improveconnection implementation simplicityVSAvoidcable tensioning capability
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent introduces a dynamic adjustment mechanism allowing the wire cable tension to be modified after installation. The wire can be unwrapped and rewrapped around the anchor pipe multiple times, or the wrapping can be adjusted to change the mechanical advantage ratio, enabling the system to adapt to varying tension requirements over time

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The wire wrapping acts as an intermediary mechanical element between the anchor pipe and the cable. By wrapping the wire around the anchor pipe multiple times, it creates a capstan effect that multiplies the tensioning force, allowing simple manual operation to achieve high cable tensions

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If anchor pipe is positioned deeper in ground, then anchoring stability is improved, but installation complexity and difficulty increase

Engineering Contradiction:
Improveanchoring stabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The anchoring system is segmented into modular components: the anchor pipe, the wire cable, and the anchor plate. This allows the anchor pipe to be installed to an optimal depth for stability while the tensioning adjustment is performed separately at the surface level through the wire wrapping mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The angled configuration of the anchor pipe allows it to self-anchor in the ground through friction and mechanical interlocking, reducing the need for complex installation equipment. The system uses the ground itself to provide the anchoring force rather than requiring additional active anchoring mechanisms

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If adjustable tensioning mechanism is added, then cable tension can be optimized, but device complexity increases

Engineering Contradiction:
Improvetension adjustment capabilityVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wire wrapping around the anchor pipe serves as a simple yet effective intermediary mechanism for tension adjustment. By controlling the number of wraps and the tightness of wrapping, the system provides continuous tension adjustment without requiring complex mechanical devices

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system adjusts tension by changing physical parameters of the wire wrapping: the number of turns around the anchor pipe, the wrapping tension, and the wrap angle. These parameter changes provide continuous adjustment capability using only simple manual operations

Inventive Principle:
Principle #35Parameter changes

AI summary

A retaining wall anchoring system comprising an anchoring pipe, the anchoring pipe anchored by a support ground, one end of the anchoring pipe being movably traversed by an eyebolt, nuts that movably interact with a threaded portion of the eyebolt to move the eyebolt relative to the anchor pipe, one end of the wire cable being secured to an anchor plate located on a front side of retaining wall distal from the anchor pipe, the wire cable traversing the retaining wall to allow the other cable end to attach to the eyebolt, the nuts being located along the eyebolt to impart an amount of tension to a combination of retaining wall, wire cable and anchor pipe.
