Solution Overview

Problem

Existing cable guides for bicycles require complex assembly processes and do not facilitate easy insertion and secure fitting into the frame or fork openings.

Innovation Solution

A cable guide comprising an upper and lower part with a form-fitting mechanism, featuring channels and slots for easy cable threading and secure fixation, utilizing chamfers and offsets to ensure easy installation and secure clamping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cable guide is inserted into the opening of the frame or fork, then the cable routing is secured and protected, but the assembly process becomes complex and time-consuming

Engineering Contradiction:
Improvecable routing securityVSAvoidassembly process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cable guide is divided into an upper part and a lower part that can be assembled separately. The upper part can be inserted into the opening first, then the lower part is attached to complete the assembly. This segmentation allows for simpler, step-by-step installation rather than requiring the entire cable guide to be installed as one complex piece.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The upper part of the cable guide can be pre-inserted into the frame or fork opening before the lower part is attached. This preliminary action simplifies the overall assembly process by breaking it into manageable steps and allowing each part to be positioned and secured independently.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the cable guide is inserted into the opening of the frame or fork, then the cable routing is secured and protected, but the installation process becomes difficult and time-consuming

Engineering Contradiction:
Improvecable routing securityVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

3Reliability

If the cable guide is inserted into the opening of the frame or fork, then the cable routing is secured and protected, but the fit in the opening is insufficient

Engineering Contradiction:
Improvecable routing securityVSAvoidfit stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The cable guide is divided into an upper part and a lower part that work together to secure the cable. The upper part provides initial positioning and protection, while the lower part completes the enclosure and ensures stable fit within the opening. This segmented approach allows each part to contribute specifically to both security and stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The upper part of the cable guide can be pre-inserted into the frame or fork opening before the lower part is attached. This preliminary action simplifies the overall assembly process by breaking it into manageable steps and allowing each part to be positioned and secured independently.

AI summary

The disclosure relates to a cable guide for a bicycle, comprising an upper part and a lower part, wherein the upper part and lower part can be fixed in place by being pulled together in an opening of a frame, and wherein at least one channel for a cable or a cable extends through the upper part and lower part. The upper part and/or the lower part has a lateral slot for threading a cable or a cable into the at least one channel.
