Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contractors face challenges in accurately determining the remaining length of cable on a reel, especially when the original length is unknown, due to the complexity of mathematical calculations required and the need for precise measurements.
Innovation Solution
A method and computer program application that calculates the remaining cable length by obtaining the distance between the top edge of a flange and the top portion of the cable, characterizing the winding pattern, and using the dimensions of the cable reel, including the flange diameter, traverse distance, and drum diameter, to generate the remaining length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex mathematical calculations are used to determine remaining cable length, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The calculation process is divided into discrete input parameters (cable diameter, reel diameter, flange diameter, traverse distance, remaining height) that can be independently measured and entered. The complex formula is segmented into manageable components that process each parameter separately to arrive at the final remaining length calculation.
Solution Approach 2:
A computing platform (smartphone or portable computer) serves as an intermediary between the user and the complex calculation. The device stores the calculation formula and processes inputs, shielding the user from mathematical complexity while maintaining precision through automated computation.
2Measurement precision
If all dimensions are required to be directly measured, then measurement precision is improved, but ease of operation and adaptability deteriorate
Solution Approach 1:
The system accepts partial measurements - users can enter the five key parameters (cable diameter, reel diameter, flange diameter, traverse distance, remaining height) without needing to measure every possible dimension. The calculation formula is designed to work with this partial set of measurements to determine remaining length.
Solution Approach 2:
The calculation approach transitions from requiring direct measurement of remaining cable length (impossible when cable is used) to measuring perpendicular parameters (heights and diameters) that can be easily obtained. The formula transforms these measurable parameters into the desired remaining length value.
3Adaptability or versatility
If original cable length is unknown, then adaptability is improved (can still calculate), but measurement precision deteriorates
Solution Approach 1:
Instead of calculating remaining length by subtracting used length from original length (which requires knowing the original), the formula inverts the approach by calculating remaining length directly from current physical state measurements (heights and diameters) without needing the original length parameter.

AI summary
The present disclosure is generally directed towards calculating a remaining length of a cable on a cable reel. Generally, a first distance between a top edge of a first flange of the cable reel and a top portion of the cable remaining on the cable reel is received at a processor. A winding characterization indicating a configuration of the cable wound on the cable reel is also received at the processor. Dimensions of the cable reel are also received at the processor and include: a diameter of the first flange, a cable reel traverse distance, and a diameter of a drum of the cable reel. The cable reel traverse distance indicates a distance between the first and second flanges of the cable reel. The remaining length of the cable on the cable reel is calculated based on the first distance, the winding characterization, and the dimensions of the cable reel.
