Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a continuous conductive sheath is used for field control, then field control precision is improved, but device complexity and installation space increase
Solution Approach 1:
The conductive element is segmented into discrete yarn pieces instead of using a continuous sheath. Each yarn piece is positioned at specific locations where field control is needed, creating a segmented field control structure that reduces complexity while maintaining precision where required
Solution Approach 2:
Field control is applied locally only where needed rather than uniformly along the entire conductor length. The discrete yarn pieces are placed at specific positions (e.g., near the conductive sheath end) to provide localized field control, reducing overall device complexity and installation space while maintaining control precision at critical points
2Reliability
If the radii of the electrode edge are made large to reduce field strength, then field control is improved, but the structural design freedom is reduced
Solution Approach 1:
Discrete conductive yarn pieces serve as intermediary elements between the conductive sheath and the insulating jacket. These yarn pieces create an intermediate field control layer that manages electric field distribution without requiring changes to the main sheath geometry, thus maintaining design freedom while improving field control effectiveness
3Measurement precision
If weakly conductive coatings are applied to the insulating sheath surface, then field control precision is improved, but manufacturing complexity increases
Solution Approach 1:
Instead of applying weakly conductive coatings to the insulating sheath surface, the invention uses thin flexible conductive yarn pieces that are wrapped around the insulating sheath. This approach achieves field control precision through the yarn's resistance properties while maintaining manufacturing simplicity, as the yarn pieces can be easily positioned and fixed without complex coating processes
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 use of an electrically conductive yarn for field control effectively reduces electric field strengths at the sheath ends, preventing discharges and protecting the insulating jacket, while allowing for flexible resistance adjustments to meet varying field control needs.
Implementation Method 1
The electric field drives a current through these materials, which, together with their resistance, leads to a voltage drop. This voltage drop, in turn, defines the potential along the surface.
Implementation Method 2
high field strengths of an electric field at the end of the sheath, which acts as an electrical electrode, can lead to significant discharges
Implementation Method 3
part of the current flows capacitively via the insulating sheath to the conductor of the conductor arrangement
