Solution Overview

Problem

Existing cable connectors in electronic devices are prone to disconnection due to vibrations, especially in mobile or portable devices, as conventional retention features like bail latches and spring-loaded snaps fail to provide stable engagement and re-seating forces against lateral and torsional forces.

Innovation Solution

A connector bracket with a body and harness system, stabilized by biasing members such as U-shaped springs, that securely engages cable connectors in multiple directions, providing a positive re-seating force to maintain connection despite vibrations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional retention features like bail latches and spring-loaded snaps are used to join cable connectors to devices, then the connectors can be easily installed and removed, but the connectors become sensitive to vibration and disconnect under vibrational stress

Engineering Contradiction:
Improveease of installation and removalVSAvoidconnection stability under vibration
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent employs a dynamic retention system where a resilient member (spring) continuously applies force to maintain engagement between the cable connector and device connector. This dynamic mechanism adapts to vibrational forces by allowing controlled movement while maintaining connection pressure, unlike static retention features that fail under vibration. The resilient member compresses and expands to counteract vibrational stresses, ensuring reliable connection while permitting easy installation and removal through simple insertion and extraction motions.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If simple connector designs are used to reduce complexity, then manufacturing and assembly are easier, but the connectors lack the structural support needed to resist lateral and torsional forces during vibration

Engineering Contradiction:
Improveconnector structure simplicityVSAvoidresistance to lateral and torsional forces
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The patent addresses the strength-deficiency problem by introducing a multi-directional retention approach. The resilient member provides retention force not only in the axial direction (easy installation/removal) but also in lateral and torsional dimensions through its resilient properties and geometric configuration. The bracket structure extends in multiple directions to engage with corresponding features on the cable connector, creating a three-dimensional engagement system that resists forces from various directions while maintaining overall design simplicity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If no retention feature is used to reduce device complexity, then the device structure is simpler, but the cable connector becomes unstable and prone to disconnection under lateral and torsional forces

Engineering Contradiction:
Improveoverall device structure simplicityVSAvoidcable connector stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The patent implements a self-regulating retention system where the resilient member automatically adjusts its force output based on the engagement state and external forces applied. When the cable connector is properly inserted, the resilient member compresses to provide optimal retention force. Under vibrational or lateral forces, the resilient member dynamically adjusts to maintain engagement without requiring external control mechanisms. This self-service approach ensures connector stability while keeping the overall device structure simple, as the retention function is inherent to the connector assembly itself rather than requiring separate active control systems.

Inventive Principle:
Principle #25Self-service
