Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing support modules for transmission line sleeves suffer from sagging due to increased weight, limited bending angles, and high manufacturing costs, while also generating dust, static electricity, and noise due to friction, which can lead to product defects and operational inefficiencies.

Innovation Solution

A support module comprising a flexible metallic plate with rotatably connected support blocks, where the upper body is made of ceramic for abrasion resistance and static prevention, and the lower body of synthetic resin for cost reduction, featuring a load supporting portion to prevent sagging and a ridge for reduced friction contact, allowing for adjustable curvature without interference with adjacent blocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the length of the sleeve and transmission line increase, then the weight increases, but sagging occurs

Engineering Contradiction:

Improvelength of sleeveVSAvoidsagging

Core Design Contradiction:

Length of moving objectVSStability of the object's composition

Solution Approach 1:

The support module is divided into an upper member and a lower member that are rotatably connected, allowing the structure to segment and adapt to different positions along the sleeve, distributing the support function across multiple modular units rather than requiring a single long bridge

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotatable connection between upper and lower members enables dynamic adjustment of the support module configuration, allowing it to adapt to varying sleeve lengths and transmission line weights without fixed geometric constraints

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If bridges are disposed across the sleeve to prevent sagging, then support is improved, but interference with transmission lines occurs

Engineering Contradiction:

Improvesupport against saggingVSAvoidinterference with transmission lines

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The support module transitions from a horizontal bridge configuration to a vertical arrangement with upper and lower members connected rotatably, moving the support function to a different spatial dimension that clears the transmission line path

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The flexible sleeve with receiving spaces accommodates the support module's upper and lower members without rigid constraints, allowing the sleeve to flex and adapt while maintaining support functionality

Inventive Principle:

Principle #30Flexible shells and thin films

3Area of stationary object

If the gap of the support module is increased, then coverage is improved, but bridge length increases and weight increases

Engineering Contradiction:

Improvecoverage of support moduleVSAvoidweight of bridge

Core Design Contradiction:

Area of stationary objectVSWeight of stationary object

Solution Approach 1:

The support function is segmented into upper and lower members that can operate independently within receiving spaces, eliminating the need for a single long bridge and reducing overall weight while maintaining coverage

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotatable connection enables the upper and lower members to dynamically adjust their positions and orientations, allowing coverage to be achieved through coordinated movement rather than increased bridge length

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If protrusion and protrusion receiving groove are used to limit rotation angle, then rotation control is improved, but manufacturing complexity increases

Engineering Contradiction:

Improverotation angle controlVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The rotation angle control is achieved by changing the geometric parameters of the protrusion and receiving groove interfaces, allowing angle limitation through dimensional design rather than complex mechanical constraints

Inventive Principle:

Principle #35Parameter changes

AI summary

Provided is a support module for a transmission line sleeve. The support module for the transmission line sleeve includes a plate formed of a flexible material that extends in a longitudinal direction so as to be bent and spread, and a support block coupled along a longitudinal direction of the plate and disposed in plurality adjacently to each other. The support block includes a plurality of lower bodies coupled to the plate at a certain interval, and an upper body coupled to an upper surface of each of the lower bodies so as to form a load supporting portion in which a portion of the upper surface of the lower body is exposed.
