Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Custodial workers face risks of electric shock, musculoskeletal injuries, and fire hazards due to electrical cords getting caught under sharp metallic corners while cleaning offices, leading to inefficiencies in cleaning tasks.
Innovation Solution
Line management devices with contoured surfaces and magnets to guide and secure utility lines, preventing them from wedging under metal structures, featuring contoured surfaces and embedded magnets for easy attachment and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custodial workers manually guide electrical cords around metal cubicle corners, then cord protection is improved, but work time increases and productivity decreases
Solution Approach 1:
A cord management device with contoured surface acts as an intermediary between the cord and the metal cubicle corner. The device intercepts the cord before it can contact the sharp metal corner, guiding it safely around the obstacle without requiring manual intervention from the worker.
Solution Approach 2:
The cord management device is positioned in advance at potential hazard locations (cubicle corners). This preliminary placement prevents cord damage before it can occur, eliminating the need for reactive manual guidance and maintaining workflow continuity.
2Productivity
If electrical cords are pulled through cubicles without guidance, then cleaning speed increases, but cord insulation stripping and safety hazards increase
Solution Approach 1:
The contoured surface device serves as a protective intermediary that cords pass through during normal operation. This allows cords to move freely at cleaning speed while the device continuously protects them from sharp metal corners and other hazards.
Solution Approach 2:
The cord management device automatically protects cords without requiring active intervention. The contoured surface geometry inherently guides and protects cords as they move through the device, providing continuous protection that operates autonomously during cleaning tasks.
3Reliability
If workers slow down to guide cords around corners, then cord protection is improved, but time loss increases and work efficiency decreases
Solution Approach 1:
By pre-positioning cord management devices at all hazard locations before cleaning begins, the system eliminates the need for workers to slow down during operation. Cords automatically pass through protected paths, maintaining full cleaning speed while ensuring continuous protection.
Solution Approach 2:
The devices act as stationary intermediaries that handle the cord protection function, freeing the worker to maintain optimal cleaning speed without being interrupted by manual cord guidance requirements at each cubicle corner.
4Productivity
If cords are allowed to move freely without management devices, then cleaning efficiency is maximized, but musculoskeletal injuries from cord catching increase
Solution Approach 1:
The cord management device intercepts cords before they can catch on metal corners or other obstacles. This eliminates the sudden stops and jerks that cause musculoskeletal injuries, allowing workers to maintain smooth, continuous motion during cleaning tasks.
Solution Approach 2:
The devices provide automatic, continuous cord protection throughout the cleaning process without requiring worker attention. This ensures cords are consistently protected against catching hazards, eliminating the physical strain and injury risks associated with manual cord management.

AI summary
A line management device for guiding local distribution of a utility line includes a main body with a middle portion, a first end portion and a second end portion. The middle portion includes a first end, a second end and a contoured surface extending between the first end and the second end. The contoured surface directs the utility line in relation to an object in a local environment. The first end portion abuts the first end of the middle portion and includes a first exterior surface shaped to direct the utility line toward the middle portion and to obstruct the utility line from passing over the first end portion. The second end portion abuts the second end of the middle portion and includes a second exterior surface shaped to direct the utility line toward the middle portion and to obstruct the utility line from passing over the second end portion.
