Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices, such as cable winches, face difficulties in assembly, disassembly, and conversion due to poorly accessible connection points and the need for large housing modifications, which complicates maintenance and adaptation.
Innovation Solution
A cable winch design featuring a base frame with separate retaining elements for each longitudinal support, allowing for easy installation, removal, and reconfiguration of supports through passage openings without loosening other supports, maintaining stability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If longitudinal supports are detachably fastened to base plates with passage openings and retaining elements, then ease of assembly and disassembly is improved, but structural complexity increases due to additional components
Solution Approach 1:
The base plate is segmented with separate passage openings for longitudinal support insertion and retaining elements for fixation. This segmentation allows independent assembly steps where supports are first inserted through passage openings and then secured with retaining elements, enabling easy disassembly by removing retaining elements without affecting other supports.
Solution Approach 2:
Passage openings are pre-provided in the base plate design, allowing longitudinal supports to be inserted before fixation. This preliminary action of providing access paths simplifies the assembly process by eliminating the need for complex alignment or disassembly of other components during support installation.
2Adaptability or versatility
If multiple longitudinal supports share common fastening points on base plates, then device complexity is reduced, but adaptability decreases when reconfiguration is needed
Solution Approach 1:
Each longitudinal support is assigned its own passage opening and retaining element on the base plate. This one-to-one correspondence allows individual supports to be independently installed, removed, or repositioned without interfering with other supports, enabling flexible reconfiguration of the base frame structure.
Solution Approach 2:
The fastening system is designed to be dynamically reconfigurable through detachable retaining elements that can be quickly installed and removed. This allows the base frame to adapt its configuration by adding or removing longitudinal supports as needed, transforming from a static to a dynamically adjustable structure.
3Ease of repair
If longitudinal supports are fixed firmly to base plates, then structural stability is improved, but ease of maintenance decreases due to poor accessibility of connection points
Solution Approach 1:
Instead of making supports removable and relying on friction or deformation for stability, the invention inverts the approach by providing dedicated passage openings and externally accessible retaining elements. This allows supports to be firmly fixed through proper mechanical fastening while maintaining accessibility for maintenance, as retaining elements can be reached from outside the base frame structure.
Solution Approach 2:
Retaining elements act as intermediary components between the longitudinal supports and base plates. These intermediaries provide stable mechanical fastening while being externally accessible, allowing maintenance personnel to access and manipulate the connection points without disassembling the entire base frame or reaching into enclosed spaces.

AI summary
A cable winch having a base frame with at least two base plates, and at least two longitudinal beams for connecting the base plates to each other. One of the base plates is designed such that the longitudinal beams can be installed or removed in the direction of the longitudinal axis of the longitudinal beams through the base plate, with passage openings in the base plate for feeding the longitudinal beams there through, and with one beam end of each of the longitudinal beams inserted into one of the passage openings. A beam end of each of the longitudinal beams is fastened to the base plate in and against the direction of the longitudinal axis of the longitudinal beam by a retaining element that is fastened to an outer face of the base plate, wherein a separate retaining element is provided for each longitudinal beam in order to enable simple assembly, disassembly, or conversion.
