Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature sensor cables with multiple sensors face challenges of large diameter and poor flexibility due to increased core wires, and identifying specific core wires among many braided strands is difficult.
Innovation Solution
A braided wire cable with insulating layers on strands to prevent electric conduction, using color combinations and twist directions as indicators to identify specific braided bundles, allowing for a smaller diameter and improved flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of core wires is increased to accommodate more sensors, then the measurement detail is improved, but the cable diameter increases and flexibility deteriorates
Solution Approach 1:
Multiple individual core wires are merged into a single braided cable structure. The patent combines many thin strands into a braided configuration, allowing multiple sensors to be accommodated within a compact diameter while maintaining flexibility through the braided architecture.
Solution Approach 2:
The patent nests multiple strands within a braided structure, where individual insulated strands are embedded within the braided cable matrix. This nesting allows numerous sensor connections to be packed into a small diameter while maintaining individual strand identifiability through color coding.
2Measurement precision
If the number of core wires is increased to accommodate more sensors, then the measurement detail is improved, but the flexibility deteriorates
Solution Approach 1:
Multiple individual core wires are merged into a single braided cable structure. The patent combines many thin strands into a braided configuration, allowing multiple sensors to be accommodated within a compact diameter while maintaining flexibility through the braided architecture.
Solution Approach 2:
The patent employs a braided cable structure that inherently provides flexibility. The braided configuration allows the cable to bend and flex easily while containing numerous insulated strands, each capable of carrying sensor signals.
3Loss of information
If conventional color coding is used to identify core wires, then identification is possible, but the cable diameter becomes too large for practical implementation
Solution Approach 1:
The patent applies local quality by using color coding only on specific identification strands within the braided structure, rather than requiring all strands to have distinctive features. This allows identification of specific bundles while keeping the overall cable compact.
Solution Approach 2:
The patent segments the braided cable into identifiable bundles with specific color patterns. By dividing the cable into distinct bundles with color-coded strands, the system enables identification without requiring each individual strand to be uniquely colored, thus reducing the overall cable diameter.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a compact and flexible cable to accommodate many sensors with reliable identification of strands, reducing costs and errors in strand identification.
Implementation Method 1
an insulating layer is provided on a surface of each of the strands in order to prevent mutual electric conduction of the strands
Implementation Method 2
a braided wire, which is typically disposed for the purpose of shielding (blocking) electromagnetic waves, for example, exhibits a shielding effect by the mutual electric conduction of strands

AI summary
A cable, which can serve as a mounting device for sensors, includes strands to be connected to the sensors. The strands are formed as a braided wire bundle. An insulating layer is provided on a surface of each of the strands in order to prevent mutual electric conduction of the strands. A particular braided bundle can be specified from among many braided bundles by using, as two indicators, a combination of colors of the insulating layers and a twist direction of the braided bundle.
