Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing clamps for retaining wires on structures, such as aircraft fuselages, lack the ability to securely hold wires of varying sizes and provide adequate protection against damage during assembly.

Innovation Solution

A clamp design featuring a band assembly with a lower band, first and second upper bands, and a cushion assembly to protect the wires, along with a fastener that adjusts the passage size to accommodate different wire diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-size clamp is used, then the structure is simple, but it cannot accommodate wires of varying sizes

Engineering Contradiction:

Improveaccommodation of varying wire sizesVSAvoidclamp structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamp employs adjustable bands that can dynamically change the passage size to accommodate different wire diameters. The bands are configured to be movable relative to each other, allowing the passage cross-section to be adjusted from small to large sizes while maintaining structural integrity.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If wires are retained without cushioning, then the clamp structure is simpler, but wire damage occurs during assembly

Engineering Contradiction:

Improvewire damage protectionVSAvoidclamp structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The clamp incorporates cushioning elements positioned within the passage to protect wires from damage during assembly and operation. These cushions are pre-installed to absorb impact forces and prevent direct contact between the wire and hard clamp surfaces, thereby preventing damage before it occurs.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Adaptability or versatility

If the passage size is fixed, then manufacturing is easier, but it cannot accommodate different wire diameters

Engineering Contradiction:

Improvepassage size adjustmentVSAvoidclamp manufacturing difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The clamp is divided into separate band segments that can be independently adjusted. This segmentation allows the passage size to be modified by repositioning individual bands rather than manufacturing entirely different clamp sizes, simplifying the manufacturing process while maintaining adaptability.

Inventive Principle:

Principle #1Segmentation
