Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable mechanisms for supporting structures like bay and bow windows lack efficient adjustment capabilities to achieve desired elevation and leveling, leading to potential sagging issues.
Innovation Solution
A cable mechanism featuring an elongated cable joined to a stud with a threaded intermediate portion and a polygonal end, allowing for adjustable tension and length adjustment using a nut and washer system to securely support windows at desired elevations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable mechanism is used to support bay and bow windows, then the windows can be supported at desired elevations, but the mechanism lacks efficient adjustment capabilities for elevation and leveling
Solution Approach 1:
The cable mechanism incorporates a threaded stud with a nut that allows dynamic adjustment of the cable length. By rotating the nut along the threaded portion of the stud, the effective cable length can be changed to achieve desired window elevation and leveling, transforming a static support system into a dynamically adjustable one.
Solution Approach 2:
The invention changes the physical parameter of cable length through the threaded stud mechanism. The stud has a threaded intermediate portion that engages with a nut, allowing precise control over the cable's effective length. This parameter change enables both elevation adjustment and leveling of the supported windows.
2Adaptability or versatility
If the cable length is fixed, then the mechanism is simple, but it cannot achieve desired elevation and leveling adjustments
Solution Approach 1:
The stud is divided into three distinct portions: a cable-receiving end portion, a threaded intermediate portion, and a polygonal opposite end portion. This segmentation allows each part to serve a specific function - the threaded portion enables adjustment, the polygonal portion provides wrench engagement, and the cable end receives the cable attachment, achieving adaptability through structural division.
Solution Approach 2:
The threaded intermediate portion of the stud acts as an intermediary mechanism between the cable tensioning system and the adjustment nut. This threaded section translates rotational motion of the nut into linear displacement of the cable, providing a mechanical advantage that enables precise length adjustment without requiring complex mechanisms.
3Ease of operation
If the stud has a circular cross section, then it is simple to manufacture, but it is difficult to prevent rotation during tensioning
Solution Approach 1:
The opposite end portion of the stud is formed with a polygonal cross section instead of a circular one. This asymmetric geometry provides flat surfaces that can be engaged by wrenches or other rotational control tools, preventing the stud from rotating during the tensioning and adjustment process while maintaining relative manufacturing simplicity.

AI summary
The cable mechanism includes an elongated flexible cable that has one end portion adapted for being attached to a supporting structure, for example, the exterior surface of a building by a cleat or clamp, and an opposite end portion mounted to one end portion of an axially elongated stud. The stud has an axial intermediate threaded portion while the end portion opposite the mounting of the cable is polygonal in transverse cross section. Fasteners such as a nut and washer may be provided on the stud in an axially adjusted position to at least aid in supporting, for example, the lower surface of a bay window in a leveled condition while the cable is attached to a building by a clamp or cleat.
