Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional busbars are susceptible to damage from foreign objects, such as tools or debris, leading to electrical shorts and obstruction of electronic device connections.

Innovation Solution

Deployable protectors on busbars automatically transition from a protective position to a stowed position when a computing device approaches, allowing connection without user intervention, while maintaining protection for other areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If deployable protectors are positioned over conductors to prevent foreign object contact, then protection against electrical shorts is improved, but accessibility for device connection is worsened

Engineering Contradiction:

Improveprotection against electrical shortsVSAvoidaccessibility for device connection

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The protectors are designed to be movable rather than fixed, transitioning between a protective position that covers the conductors and a retracted position that exposes them. This dynamic capability allows the same structure to provide protection during idle periods and accessibility during connection operations, resolving the contradiction between reliability and ease of operation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system automatically positions the protectors in the protective state before any foreign object contact occurs, and preemptively transitions to the retracted state when a device approaches. This preliminary action eliminates the need for manual intervention and ensures protection is always active unless connection is intended, resolving the contradiction between automatic protection and ease of operation

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual protection measures are used, then protection effectiveness is improved, but user intervention and time consumption are worsened

Engineering Contradiction:

Improveprotection effectivenessVSAvoiduser intervention time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The busbar assembly performs protection management autonomously through sensors that detect device approach and automatically trigger protector retraction. The system serves itself by eliminating the need for user awareness or action, resolving the contradiction between effective protection and time loss from manual intervention

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses sensors to continuously monitor the environment around the busbar and provides feedback to the control system. When a device is detected approaching, the feedback loop triggers automatic protector retraction. This closed-loop feedback mechanism ensures timely protection while eliminating manual intervention, resolving the contradiction between protection effectiveness and user intervention time

Inventive Principle:

Principle #23Feedback

AI summary

The discussion relates to busbars that are protected from unintentional contact. One example includes a liquid immersion tank and a protected automatic busbar assembly positioned in the liquid immersion tank. The protected automatic busbar assembly can include a conductor and a deployable protector biased over the conductor. The example can include a computer that includes a device controller and an electrical connector. The device controller can be configured to overcome the bias and cause the deployable protector to transition away from the conductor to allow the conductor to be engaged by the electrical connector to couple the computer to the conductor of the protected automatic busbar assembly.
