Cable Measuring Tool with Cutaway for Bend Radius Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In server system assembly, cables often fail to meet the specified minimum bend radius due to space limitations and human factors, necessitating a quick and effective measuring tool for inspecting cable diameters and bend radii.
Innovation Solution
A cable measuring tool with a first end portion featuring a rounded edge and an oblong-shaped cutaway, designed to fit at least half of a cable, and a second end portion with a second edge, allowing for the measurement of cable diameters and bend radii by comparing the rounded edge radius with the cable's bend radius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional measurement methods are used for cable bend radius, then measurement accuracy can be maintained, but inspection time increases and productivity decreases
Solution Approach 1:
The patent employs simple, inexpensive template tools with predetermined bend radius markings that can be quickly applied and discarded or reset. These templates are designed for single-use or limited-use scenarios where rapid inspection is prioritized over long-term durability, enabling fast visual comparison without complex measurement procedures
Solution Approach 2:
The invention changes the measurement approach from precise numerical measurement to visual comparison against standardized parameter templates. By providing pre-marked templates with specific bend radius values (e.g., 5mm, 10mm, 15mm), the system transforms the inspection process into a simple visual match task, dramatically reducing measurement time while maintaining adequate precision for quality control
2Measurement precision
If detailed measurement procedures are followed to ensure cable compliance, then measurement precision is improved, but operation complexity increases
Solution Approach 1:
The templates are pre-prepared with accurate bend radius markings and specifications before use. This preliminary action of creating standardized reference templates eliminates the need for operators to perform complex measurements during inspection, as they simply need to visually compare the cable against the pre-marked templates, thereby maintaining precision while simplifying operation
Solution Approach 2:
The invention uses template copies of the ideal bend radius geometry as reference standards. These templates are physical or visual copies of the correct cable bend shape and dimensions, allowing operators to compare actual cable bends against these reference copies without requiring sophisticated measurement equipment or complex procedures
3Reliability
If manual measurement methods are used, then device complexity is reduced, but measurement reliability decreases due to human error
Solution Approach 1:
The templates are designed to be self-explanatory and self-verifying, with clear markings and visual indicators that guide the operator through the inspection process without requiring additional tools or complex procedures. The templates themselves provide the measurement criteria and the comparison mechanism, making the system self-sufficient and reducing reliance on operator skill while maintaining reliability
Solution Approach 2:
The templates incorporate visual indicators such as color-coded zones or highlighted areas that change or stand out when the cable bend matches the correct radius. This use of color and visual contrast provides immediate, unambiguous feedback to the operator, eliminating guesswork and human error while keeping the device simple and easy to use

AI summary
A cable measuring tool includes a first end portion and a second end portion. The first end portion includes a first rounded edge and a cutaway. The cutaway is configured to fit at least a half of a cable having a maximum diameter. The first rounded edge has a radius greater than the maximum diameter of the cable. The second end portion is opposite from the first end portion. The second end portion includes a second edge. The first rounded edge of the first end portion and the second edge of the second end portion define a length of the cable measuring tool.
