Solution Overview

Problem

Existing docking stations require two hands to remove electronic devices due to high extraction forces, can cause damage from off-axis removal, and are inefficient in material usage, as they rely on weight and static connectors.

Innovation Solution

A docking station with a hinged ejection mechanism that allows the electrical connector to rotate and change angles, reducing extraction force and minimizing wear-and-tear, while using a four-bar linkage to facilitate off-axis removal and efficiently use materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a heavy docking station is used to overcome extraction force, then the device can be removed with one hand, but material usage increases and transportation cost increases

Engineering Contradiction:
Improveone-handed device removalVSAvoidmaterial usage
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The connector is made movable rather than static, allowing it to rotate and adjust its angle during device removal. This dynamic capability enables the connector to accommodate off-axis removal forces without requiring the docking station to be heavy, thus achieving one-handed operation with lighter materials

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connector's angular position is changed during the removal process. By allowing the connector to rotate from its initial parallel position to a non-parallel position, the system adapts to varying removal angles and forces, reducing the need for excessive weight to handle extraction forces

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If a static connector is used, then the structure is simple, but off-axis removal causes binding, breakage, or damage to the electronic device

Engineering Contradiction:
Improveconnector structureVSAvoidconnector durability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The connector is designed to rotate about an axis, transforming it from a static to a dynamic component. This rotation capability allows the connector to accommodate off-axis removal forces smoothly, preventing binding and breakage while maintaining structural simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotating connector mechanism preemptively counteracts off-axis removal forces by allowing angular adjustment before damage can occur. This preliminary adaptation prevents binding and breakage that would otherwise happen with a static connector

Inventive Principle:
Principle #9Preliminary anti-action

3Reliability

If extraction force is increased to ensure secure connection, then connector engagement is more reliable, but device removal becomes more difficult and may require two hands

Engineering Contradiction:
Improveconnector engagementVSAvoiddevice removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The rotating connector mechanism allows the system to maintain strong engagement during normal use while enabling easy removal when needed. The rotation capability provides a release mechanism that overcomes high extraction forces, allowing one-handed removal even with secure connector engagement

Inventive Principle:
Principle #15Dynamics

AI summary

Disclosed is a docking station for holding an electronic device including a main body, a vertical support, a horizontal support, a cut-out in the horizontal support, and an ejection mechanism. The ejection mechanism includes a base member, a top member, an extension member disposed on the top member, an electrical connector disposed on the extension member, and a first and second bars hingedly connecting the base member to the top member. The top member is configured to be disposed in a first position in which the electrical connector is disposed at a first height with respect to the horizontal support and substantially parallel to the vertical support. The top member is further configured to be disposed in a second position in which the electrical connector is disposed at a second height with respect to the horizontal member and substantially non-parallel with the vertical support. The second height is less than the first height.
