Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking devices for elongated objects, such as cables, face issues with material brittleness leading to detachment, complicated attachment of identification plates, and environmental degradation of inscriptions due to enclosed atmospheres, resulting in poor stability and durability.
Innovation Solution
A marking device composed of hard plastic and elastically deformable components, featuring a partition wall that spans the receiving channel with an opening for frictional attachment and an anchoring section for stability, allowing for secure attachment and preventing material separation even if the partition becomes brittle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elastomeric material is used for the cable grommet, then the device can be easily attached to the cable by elastic deformation, but the material becomes brittle over time causing the grommet to fall off
Solution Approach 1:
The marking device is divided into two separate components: a rigid plastic marking device body and a separate elastically deformable partition. The partition is inserted into the marking device through a breaking point, creating a segmented structure where each component performs its specific function independently. This segmentation allows the elastic partition to provide easy attachment while the rigid body maintains long-term structural stability.
Solution Approach 2:
The invention combines two different materials with complementary properties: rigid plastic (polycarbonate) for the marking device body providing stability and durability, and thermoplastic elastomer for the partition providing elastic deformation capability. This composite material approach allows both components to发挥 their respective advantages without the drawbacks of using a single material for both functions.
2Reliability
If the receiving channel is made narrow to hold identification plates securely, then the holding force is sufficient, but the plates can only be inserted with considerable force and the enclosed atmosphere degrades the lettering
Solution Approach 1:
The partition is designed with a breaking point that allows it to be separated from the marking device body during insertion. The partition is inserted first through the breaking point, creating space for the identification plate to be easily placed into the receiving channel without requiring excessive force. After insertion, the partition can be deformed elastically to secure the plate firmly in place.
Solution Approach 2:
The partition is designed to be dynamically deformable during the insertion process. It can be compressed or stretched to accommodate the identification plate during insertion, then returns to its original shape to provide secure holding force. This dynamic behavior allows easy insertion while maintaining strong holding capability.
3Reliability
If a deformable partition is arranged in the receiving channel to hold the device to the cable, then friction attachment is achieved, but forming the partition against an inner surface is not stable
Solution Approach 1:
The partition is made of thermoplastic elastomer material that combines elastic deformability with structural stability. This material allows the partition to deform elastically for friction attachment while maintaining sufficient structural integrity and stability during operation. The material properties ensure both the friction attachment capability and the partition's compositional stability.
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 solution provides a stable and durable attachment to elongated objects, ensuring the marking device remains in place without slipping or falling, while allowing for easy labeling and maintaining inscription integrity.
Implementation Method 1
The partition's elastic restoring force keeps it in contact with the object, so that the marking device is held in place by friction and cannot slip.
Implementation Method 2
The partition's elastic restoring force keeps it in contact with the object, so that the marking device is held in place by friction and cannot slip.
