Geared Suspension Clamp for Stable Cable Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices for elongated objects, such as cables or wires, lack a stable and efficient design that prevents tilting and optimizes material usage, leading to inadequate clamping force and increased material consumption.
Innovation Solution
A suspension device with pivotally mounted gripping shanks on separate axes, equipped with a gear mechanism for synchronous movement and spring members for enhanced clamping, along with covering plates for safety and assembly, allowing for a balanced and reduced design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If gripping shanks are mounted on a common axis of pivotation, then the device structure is simpler, but the clamping force is weaker and tilting cannot be prevented
Solution Approach 1:
The common axis of pivotation is segmented into two separate parallel axes, with each gripping shank mounted on its own axis. This segmentation allows independent control and optimization of each shank's clamping action, resulting in stronger overall clamping force while preventing tilting through the gear mechanism that ensures synchronous movement.
Solution Approach 2:
The gripping shanks are designed to move dynamically between open and closed positions through pivotal movement on separate axes. The gear mechanism coordinates this dynamic movement to ensure both shanks move synchronously, maintaining stability while enabling strong clamping force during the closing action.
2Quantity of substance
If gripping shanks are mounted on a common axis of pivotation, then fewer materials are needed for the pivot mechanism, but the device height is larger and material consumption increases
Solution Approach 1:
The pivot mechanism transitions from a vertical common axis arrangement to a horizontal separate axes arrangement. This dimensional change reduces the vertical height of the device while distributing the material consumption across two separate but simpler pivot mechanisms, ultimately reducing total material usage.
3Force
If gripping shanks pivot about separate axes, then clamping force is stronger and tilting is prevented, but the device complexity increases
Solution Approach 1:
A gear mechanism is introduced as an intermediary element between the two gripping shanks. This gear mechanism coordinates the pivotal movement of both shanks, ensuring they move synchronously about their separate axes. The gear mechanism adds controlled complexity that enables stronger clamping force and tilt prevention while maintaining overall system coherence.
4Quantity of substance
If gripping shanks pivot about separate axes, then material consumption is reduced, but the manufacturing complexity increases
Solution Approach 1:
The device is segmented into modular components: a base part with two separate pivot axes, two independent gripping shanks, and a gear mechanism. This segmentation allows each component to be manufactured separately using standard processes, reducing overall manufacturing complexity despite the increased number of parts, while also reducing total material consumption.

Function Achieved in This Case

Implementation Method 1
at least one spring member acting between the gripping shanks, against the action of which the gripping shanks are pivotable from the closed position towards the open position
Implementation Method 2
at least one gear mechanism, which comprises a first gear member rigidly connected to the first gripping shank and a second gear member rigidly connected to the second gripping shank, said first and second gear members being in engagement with each other and arranged to be turned in relation to each other when the gripping shanks are pivoted in relation to each other
