Solution Overview

Problem

Existing input/output connectors are prone to damage when a cable terminal is inserted in the wrong direction or misaligned.

Innovation Solution

An input/output connector design featuring a cover that is hinged to the housing, an elastic body, and an insertion hole with adjustable size, preventing incorrect insertion by rotating the cover to accommodate the cable terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cable terminal is inserted in the wrong direction or misaligned, then the connector structure remains simple and open, but the connector is damaged

Engineering Contradiction:
Improveconnector damage preventionVSAvoidconnector structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cover is positioned in advance to cover the insertion hole, preventing incorrect insertion before it occurs. The hinged cover structure is pre-configured to rotate and block the hole when needed, acting as a preventive measure rather than a reactive one.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The elastic body acts as an intermediary between the cover and the housing, providing the necessary force to rotate the cover and block the insertion hole. This intermediary mechanism enables the cover to respond dynamically to insertion attempts without direct mechanical linkage to the housing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the insertion hole size is fixed, then the connector structure is simple, but incorrect insertion cannot be prevented

Engineering Contradiction:
Improveinsertion accuracyVSAvoidinsertion hole structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The insertion hole's effective size is made dynamic through the rotatable cover. When the cover rotates, it changes the opening size of the insertion hole, allowing it to adapt between a blocked state (preventing incorrect insertion) and an open state (allowing correct insertion).

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The physical parameter of the insertion hole (its effective opening size) is changed by rotating the cover. This parameter change allows the system to transition between different functional states: blocking incorrect insertions while permitting correct ones.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the cover is fixed to the housing, then the structure is simple, but the cover cannot rotate to block the insertion hole

Engineering Contradiction:
Improveinsertion blocking functionVSAvoidcover connection structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cover connection is made dynamic through the hinged structure. Instead of being fixed, the cover can rotate around the hinge axis, enabling it to transition between covering and exposing the insertion hole based on insertion attempts.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic body serves as an intermediary that provides the rotational force to the cover. This intermediary mechanism allows the cover to rotate without direct mechanical connection to the housing, enabling the blocking function while maintaining structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)
