Solution Overview

Problem

Existing methods for binding cable bundles in the aeronautical industry are labor-intensive, costly, and prone to musculoskeletal disorders, with significant offcuts and material waste, while requiring manual labor and being unsuitable for high-temperature environments.

Innovation Solution

A method using simple strip bindings that eliminate self-locking knots, employing adhesive bonding to secure the lacing without knots, allowing for automation and using fast-setting glues to ensure quick and secure binding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual knotted wire binding technique is used, then cable bundles can be bound securely, but production time is long and labor costs are high

Engineering Contradiction:

Improvebinding securityVSAvoidproduction speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical knot-tying system with an automated adhesive bonding system. A dispensing device applies adhesive to pre-formed bindings that are then automatically positioned and secured around cable bundles, eliminating the need for manual knot manipulation while maintaining binding security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The bindings are pre-formed with adhesive already applied or pre-positioned before the binding process. This preliminary preparation allows for rapid automated application without requiring time-consuming manual knot formation during the actual binding operation.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If automatic clamps with protruding heads are used, then binding speed increases, but the protruding heads can get trapped in systems or tear insulation mats

Engineering Contradiction:

Improvebinding speedVSAvoiddamage to surrounding elements

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent uses simple strip bindings that are consumed in the binding process rather than reusable clamps with protruding heads. These flat bindings are designed to be disposed of after use, eliminating the risk of protruding elements damaging surrounding components while maintaining high binding speed.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Strength

If bands with adhesive and mechanical attachment elements are used, then binding strength increases, but the bands become thick and easily attach to surrounding elements

Engineering Contradiction:

Improvebinding strengthVSAvoidbinding thickness

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent applies adhesive locally at specific bonding points on the bindings rather than covering entire surfaces. This localized adhesive application provides sufficient binding strength while keeping the bindings thin and preventing unwanted attachment to surrounding elements.

Inventive Principle:

Principle #3Local quality

4Strength

If bindings with adhesive are used, then binding strength increases, but they cannot be prepared upstream and packaged in the form of a long reel

Engineering Contradiction:

Improvebinding strengthVSAvoidpackaging capability

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent segments the binding system into discrete pre-formed bindings that can be individually prepared with adhesive and then packaged. This segmentation allows bindings to be manufactured upstream, packaged in reels or containers, and stored for later automated application without compromising adhesive effectiveness.

Inventive Principle:

Principle #1Segmentation

AI summary

A method for binding a cable bundle using simple strip bindings, where producing a binding includes lacing the strip around the bundle and producing a stop by adhesively bonding the lacing to itself by applying at least one glue dot to the strip once the lacing has been carried out, without a self-locking knot being formed. A piece of looped strip is wound around the cable bundle, the two strands of the strip are introduced into the loop, a glue dot is deposited onto the strands close to the loop, and the strands are pulled to trap the glue dot between the strands and the peak of the loop. Eliminating self-locking knots gains time in the production of the bindings, limits the risk of MSDs in operators, and to automates the process increasing productivity and reducing both the amount of binding strip required and the amount of offcuts.
