Solution Overview
Problem
Existing dental implant systems face challenges in effectively combating peri-implantitis, a condition leading to inflammation and tissue destruction due to bacterial colonization on the implant surface, necessitating a solution that can kill and remove bacteria while preserving the implant and ensuring reliable electrical connectivity for treatment systems.
Innovation Solution
A contacting system for a cable harness in a treatment system that allows for simple, reliable, and cost-effective electrical connection using transversely aligned contact pins, which also serve as mechanical fixings, ensuring stable contact points without precise alignment, and incorporates a hose with integrated electrical conductors for easy handling and high reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contact pins are aligned transversely to the cable harness, then ease of operation is improved, but manufacturing precision requirements worsen
Solution Approach 1:
The contact pins are arranged transversely (perpendicularly) to the longitudinal direction of the cable harness, changing the dimensional relationship from parallel to perpendicular. This allows the cable harness to be simply placed over the contact pins without requiring precise longitudinal alignment, as the transverse orientation provides natural positioning and the connection can be made by simple insertion rather than precise matching of aligned features.
2Device complexity
If contact pins serve both electrical contacting and mechanical fixing, then device complexity is reduced, but reliability requirements worsen
Solution Approach 1:
The contact pins perform dual functions: they provide electrical contacting between the cable harness conductors and the treatment system, and simultaneously serve as mechanical fixings to secure the cable harness in position. This merging of electrical and mechanical functions into a single component reduces the overall device complexity by eliminating the need for separate fastening elements, while the transverse arrangement ensures both functions are achieved reliably through a single connection action.
