Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling and maneuvering large and heavy electricity cables in tight spaces, such as basements or crawl spaces, are cumbersome and require excessive manual effort, lacking the ability to efficiently bend and straighten cables without occupying too much space.
Innovation Solution
A compact device with a drive section, bending section, and aiming section, featuring adjustable rolls and remote control capabilities, allowing for simultaneous feeding, bending, and straightening of cables, with a maximum weight of 35 kg and dimensions suitable for tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If existing devices for feeding cables are used, then cable feeding capability is provided, but the devices are too large for tight spaces
Solution Approach 1:
The device is divided into separate functional modules: a drive section with drive rolls for feeding the cable, and a bending section with bending rolls for shaping the cable. These modules can be positioned independently within the tight space, allowing the overall device footprint to be minimized while maintaining full functionality.
Solution Approach 2:
The device utilizes vertical space by positioning drive rolls and bending rolls at different heights. The bending rolls are arranged above and below the drive rolls, creating a compact configuration that fits within limited horizontal space while providing effective cable handling in three dimensions.
2Ease of operation
If manual cable handling is performed in tight spaces, then cable positioning is possible, but excessive manual power is required and safety risks increase
Solution Approach 1:
The drive rolls are powered to automatically feed the cable through the tight space, eliminating the need for workers to manually pull heavy cables. The bending rolls are positioned to automatically guide and shape the cable as it passes through, reducing manual intervention and associated safety risks.
Solution Approach 2:
Manual mechanical force applied by workers is replaced with a powered drive system. The drive rolls use rotational mechanical force to pull the cable, while the bending rolls use controlled mechanical pressure to shape the cable, both reducing the physical strain on workers and improving safety.
