Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable holding structures face challenges in maintaining the positional integrity of electrical wires and their sheaths, leading to potential shifting and compromised waterproofing.
Innovation Solution
A holding structure comprising a first and second holder with clamping portions, a rubber plug with through-holes for the wires, and a binding member to securely clamp and seal the cable, preventing positional shifting and ensuring effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rubber plug with insertion holes is used to seal electrical wires, then waterproofness is improved, but positional shifting of sheath and wires occurs
Solution Approach 1:
The sealing system is divided into multiple functional components: a rubber plug for waterproof sealing, a first holder with first clamping portion for positional stabilization, a second holder with second clamping portion for additional clamping, and a binding member for securing the holders. Each component addresses specific requirements, allowing the rubber plug to focus on waterproofness while the holder system handles positional stability.
Solution Approach 2:
The first holder and second holder act as intermediary components between the rubber plug and the cable assembly. These holders clamp the cable and suppress positional shifting of the sheath and electrical wires, thereby preventing misalignment between the insertion holes and wires while allowing the rubber plug to perform its sealing function effectively.
2Stability of the object's composition
If multiple holders and clamping portions are added to suppress shifting, then positional stability is improved, but device complexity increases
Solution Approach 1:
The first holder and second holder are combined with the rubber plug assembly to form an integrated sealing and positioning system. The holders are positioned to clamp the cable at locations that work cooperatively with the rubber plug, creating a unified structure that achieves both sealing and positional stability without requiring completely separate systems.
Solution Approach 2:
The first holder and second holder serve multiple functions: they clamp the cable to suppress positional shifting, provide structural support for the rubber plug assembly, and work together with the binding member to secure the entire assembly. This multi-functionality reduces the need for additional specialized components.
3Reliability
If a binding member is added to secure the holders, then reliability of clamping is improved, but ease of manufacture decreases
Solution Approach 1:
The binding member is designed to wrap around the first holder and second holder, creating a self-securing mechanism that maintains clamping force without requiring additional fasteners or complex assembly steps. The binding member's configuration allows it to automatically engage and secure the holders in place, reducing the need for extra manufacturing operations.
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
The structure effectively suppresses shifting of the sheath and electrical wires, maintaining their relative positions and ensuring reliable sealing against water or oil intrusion.
Implementation Method 1
When the cable is clamped between the first clamping portion and the second clamping portion, a force is applied from the first clamping portion and the second clamping portion to the cable in a direction in which the sheath is clamped
Implementation Method 2
the first clamping portion and the second clamping portion receive a force in a radial direction from the binding member that is wrapped around the first clamping portion and the second clamping portion. Accordingly, a force is applied to the sheath in a direction in which the diameter of the sheath is reduced inward in the radial direction of the sheath

AI summary
A holding structure for a cable includes a cable in which electrical wires extend out from an end portion of a sheath, a first holder provided with a first clamping portion, a second holder provided with a second clamping portion configured to clamp the cable between the first clamping portion and the second clamping portion, a rubber plug that has a plurality of through-holes through which the electrical wires respectively are passed, and that is held by the first holder and the second holder, in a state in which the rubber plug is fitted around the end portion of the sheath, and a binding member that is wrapped around the first clamping portion and the second clamping portion.
