Modular Cable Guide for Winch Drum Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable winch designs with split ring cable guides require multiple injection molds for different segments, increasing tool costs as the cable drum diameter grows, and lack a modular structure for adaptable installation and assembly.
Innovation Solution
A cable winch with base segments having multiple bores for torque arms and add-on elements, allowing for modular assembly and adaptation, with identical segments simplifying production and reducing part variety, and using interchangeable inserts to account for different engagement elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different segments of the cable guide are designed with different functions (guide segment and hold-down segment), then the cable guide can perform its guiding and holding functions effectively, but the variety of parts increases and requires multiple injection molds, increasing tool costs
Solution Approach 1:
The cable guide is divided into two identical basic segments that can be used in different positions (guide position and hold-down position). This segmentation allows the same component design to fulfill multiple functional requirements, reducing part variety while maintaining functional effectiveness.
Solution Approach 2:
The basic segment is designed as a universal component that can serve dual purposes: as a guide segment when positioned at the cable entry point and as a hold-down segment when positioned at the cable exit point. This multi-functionality eliminates the need for separate specialized components, reducing tool costs while maintaining reliable cable guidance and holding functions.
2Strength
If the cable drum diameter increases, then the cable capacity and load-bearing capability improve, but the segments and tool costs increase accordingly
Solution Approach 1:
The cable guide is segmented into identical modular basic segments that can be produced using a single injection mold. This segmentation strategy allows the same tooling to serve all segment production regardless of cable drum size, preventing tool cost escalation as the cable drum diameter increases.
Solution Approach 2:
While the basic segment design remains constant, the quantity of segments and their spatial arrangement can be adjusted to accommodate different cable drum diameters. This parameter adjustment approach allows the system to scale with cable drum size without requiring new tooling, maintaining manufacturing cost efficiency across different capacity levels.
3Ease of manufacture
If the cable guide is designed as a fixed structure, then the assembly is simple, but it cannot be adapted to different installation positions and cable run-off points
Solution Approach 1:
The cable guide is constructed from multiple identical basic segments arranged in a ring, which can be positioned at different locations around the cable drum. This segmented modular structure maintains assembly simplicity while enabling adaptation to various installation positions and cable run-off points through strategic placement of segments.
Solution Approach 2:
The cable guide structure incorporates adjustable elements including torque arms that can be repositioned and add-on elements that can be attached at different locations on the basic segments. This dynamic configurability allows the same basic structure to adapt to different installation scenarios while maintaining simple assembly procedures.
4Reliability
If multiple types of segments are used in the cable guide, then the guiding and holding functions are optimized, but the assembly complexity increases
Solution Approach 1:
The cable guide uses identical basic segments repeated around the ring, eliminating the need to assemble different types of segments. This segmentation approach simplifies assembly while maintaining optimized guiding and holding functions through the strategic positioning of identical segments at different locations around the cable drum.

AI summary
The cable guide has a cable drum having a cable groove. The cable guide has two base segments expanding into a ring. The base segments (2a, 2b) are guided in the cable groove by an engaging element (10) and supported against the cable winch by a torque support (9). The elements for guiding and holding down a cable are arranged on the base segments. The torque support and the add-on element for guiding and holding down the are variably arranged on the base segments. The base segments are identical except for their engaging elements.
