Solution Overview

Problem

Existing connector arrangements for electrical devices, particularly in vehicles, face challenges in achieving a technically simple and cost-effective floating mounting that allows for movement compensation along multiple degrees of freedom while maintaining a defined spatial starting position, especially in applications where mechanical stress and vibrations are prevalent.

Innovation Solution

A connector arrangement featuring an electrical connector with a housing component and elastic elements that support movement along translational degrees of freedom, utilizing a combination of bearing recesses and elevations to guide and limit mobility, allowing for compensating movements while ensuring a defined initial position through elastic restoring forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a connector is rigidly mounted to the battery housing, then mechanical stability is improved, but mechanical stress and damage risk increase due to movement transmission

Engineering Contradiction:
Improvemechanical stabilityVSAvoidconnection reliability
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The connector is mounted on elastic elements (springs) that allow dynamic movement compensation. The elastic elements enable the connector to move with the battery while maintaining connection integrity, transforming the rigid static mounting into a dynamic flexible mounting that absorbs movement forces.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Elastic elements are introduced as intermediary components between the battery housing and the connector. These intermediaries absorb and compensate for movement forces, preventing direct transmission of mechanical stress from the moving battery to the connector.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple elastic elements are used to achieve floating mounting and movement compensation, then movement compensation capability is improved, but device complexity and costs increase

Engineering Contradiction:
Improvemovement compensation capabilityVSAvoidconnector assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The elastic elements serve multiple functions simultaneously: they provide floating mounting, enable movement compensation in multiple degrees of freedom, and apply restoring forces to maintain connector positioning. This multi-functionality reduces the need for additional separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting function and movement compensation function are merged into a single elastic element system. The same elastic elements that provide the floating mounting also compensate for movements, eliminating the need for separate mounting structures and movement compensation mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the connector is designed to float on elastic elements, then movement compensation is improved, but defined spatial positioning in unplugged state deteriorates

Engineering Contradiction:
Improvemovement compensationVSAvoidspatial positioning precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The elastic elements provide continuous feedback forces (restoring forces) that automatically return the connector to its defined spatial position after any displacement. This feedback mechanism ensures that the connector maintains precise positioning while still allowing for movement compensation during operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The elastic restoring forces act as counterforces to any displacement forces acting on the connector. When the connector moves from its defined position, the elastic elements generate opposing forces that push it back, effectively counterbalancing any positional deviations and maintaining precision.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
