Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for tightening and loosening turnbuckles, particularly those used for fastening shipping containers, are labor-intensive and slow due to the need for manual operation with hand tools.
Innovation Solution
A device with a drive system comprising a driveshaft, main cogwheel, reduction gear, and an electric motor, along with a removable battery, that allows for efficient rotation of the turnbuckle, either with an integrated motor or using external power sources like a cordless drill, to facilitate faster tightening and loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand tools are used to tighten and loosen turnbuckles, then the operation can be performed manually, but the process is slow and labor-intensive
Solution Approach 1:
The patent replaces manual mechanical operation with an automated motor-driven system. The device incorporates an electric motor that rotates the turnbuckle automatically, eliminating the need for manual handling with hand tools. This substitution directly addresses the contradiction by maintaining ease of operation (the device is still manually operated) while dramatically improving productivity through automated rotation.
Solution Approach 2:
The patent introduces dynamic elements including a motor that can rotate in both directions, a reversible gear mechanism, and a clutch system that allows bidirectional rotation. This dynamic design enables the same device to both tighten and loosen turnbuckles efficiently, improving productivity without compromising operational flexibility.
2Productivity
If a motor-driven device is used to rotate the turnbuckle, then productivity increases, but device complexity increases
Solution Approach 1:
The patent divides the device into distinct functional modules: a motor unit, a gear reduction unit, a clutch mechanism, and a frame. This segmentation allows each component to perform its specific function independently, making the overall complex system manageable and maintainable while achieving high productivity through coordinated operation of these modular components.
Solution Approach 2:
The patent designs a multi-functional device that can both tighten and loosen turnbuckles using the same motor-driven mechanism. The reversible motor and bidirectional clutch system allow a single device to perform multiple operations, reducing the need for separate tools and justifying the increased complexity through versatility and improved productivity.
3Force
If reduction gear is used to increase torque, then the ability to tighten turnbuckle improves, but the number of moving parts increases
Solution Approach 1:
The patent introduces a gear reduction mechanism as an intermediary between the motor and the turnbuckle rotation. This gear system acts as a mediator that transforms the motor's high-speed, low-torque output into low-speed, high-torque rotation suitable for tightening turnbuckles, while the clutch mechanism serves as another intermediary to enable bidirectional control.

AI summary
The invention concerns a device and a method for tightening and loosening turnbuckles. The device (100) has a drive system comprising a driveshaft (104), a main cogwheel (106) and a reduction gear between the driveshaft (104) and the main cogwheel (106). The reduction gear transmits rotation of the driveshaft (104) to rotation of the main cogwheel (106) with a lower rotation speed and increases torque. The main cogwheel (106) has an opening (108), which is configured to accommodate a part of the turnbuckle in such a way that the rotation axis of the turnbuckle and the rotation axis of the main cogwheel are coaxial.
