Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for increasing the number of electrodes in multiconductor plugs and jacks face limitations, such as subdividing the post axis or adding electrodes to the plug cover, which complicates the structure and increases diameter, necessitating a novel approach to enhance electrode count.
Innovation Solution
A multiconductor jack and plug design featuring a rod-shaped shaft with exposed electrodes and a flat electrode on the flange portion, where the flat electrode is perpendicular to the axis, allowing for increased electrode count without complicating the structure, using a casing with electrically conductive terminals that generate elastic forces for reliable contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If electrodes are provided on the interior and exterior surfaces of the plug cover, then the number of electrodes increases, but the diameter of the jack increases and the structure becomes complicated
Solution Approach 1:
The invention transitions from conventional axial electrode arrangement to a radial/directional arrangement by introducing a flat electrode extending perpendicular to the axial direction. This dimensional change allows additional electrodes to be positioned without increasing the jack's diameter, effectively adding electrodes in a new spatial dimension rather than expanding the existing structure.
Solution Approach 2:
The invention segments the electrode configuration into distinct functional groups: conventional axial electrodes on the shaft portion and a separate flat electrode structure extending radially. This segmentation allows each electrode type to be optimized independently, with the flat electrode providing additional contact points without interfering with the axial electrode arrangement, thereby increasing total electrode count without proportionally increasing structural complexity.
2Quantity of substance
If the post is subdivided in the axial direction to increase electrode number, then the number of electrodes increases, but there is a limit to how much the number can be increased
Solution Approach 1:
Instead of continuing to subdivide the post axially (one-dimensional approach), the invention introduces electrodes in a radial direction perpendicular to the axial direction. This creates a two-dimensional electrode distribution pattern, allowing additional electrodes to be added without increasing the post length, thereby overcoming the limitation of axial subdivision.
3Quantity of substance
If the post is subdivided in the axial direction, then the number of electrodes increases, but the structure becomes more complex
Solution Approach 1:
The invention separates the electrode system into modular components: the shaft portion with axial electrodes and the flat electrode structure extending radially. This segmentation allows the flat electrode to be added as a distinct element rather than requiring complex reconfiguration of existing axial electrodes, thereby increasing electrode count while maintaining relative structural simplicity.

AI summary
A multiconductor plug (10) has exposed electrodes (11a through 11e) on a shaft portion (14) and an electrode (11f) located at an annular flat portion of a flange portion (15) perpendicular to an axial direction. A multiconductor jack (20) has a casing (21) forming a space capable of being occupied by the shaft portion (14) of the multiconductor plug (10), electrically conductive terminals (23a through 23e) that come into electrically conductive contact with the electrodes (11a through 11e) of the shaft portion (14) of the multiconductor plug (10), and an electrically conductive terminal (23f) having a contacting portion (23f1) for making electrically conductive contact with the flat electrode (11f) perpendicular to the axial direction and an elastic portion (23f3) that extends in the axial direction. The contacting portion (23f1) of the electrically conductive terminal (23f) presses against the electrode (11f) as a result of elastic forces parallel to the axial direction.
