Solution Overview

Problem

Existing charging device systems face challenges in achieving a compact design and optimizing assembly for different vehicle types due to modular designs and the need for direct attachment to vehicle bodies, which complicates the attachment process and assembly.

Innovation Solution

A holding device with a movably attached securing frame that tensions and secures locking hooks in different positions, allowing for easy assembly and secure locking with a locking contour, enabling variation in application and simplifying the assembly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a modular design with a central module and multiple end modules is used for charging devices, then adaptability to different vehicle types and charging standards is improved, but device complexity and difficulty of assembly increase

Engineering Contradiction:
Improveadaptability to different vehicle typesVSAvoidcomplexity of modular system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base plate is designed as a universal mounting component that can accommodate different charging device configurations. The securing frame with its movable design and multiple locking hooks can secure various types of charging devices to the same base plate, eliminating the need for different mounting solutions for different vehicle types.

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

Solution Approach 2:

The mounting system is divided into separate functional components: a base plate for vehicle attachment, a movable securing frame for device retention, and locking hooks for securing the charging device. This segmentation allows each component to be optimized independently and simplifies assembly.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the securing frame is rigidly fixed to the base plate, then structural stability is improved, but ease of operation for mounting and dismounting charging devices deteriorates

Engineering Contradiction:
Improvestructural stability of mounting systemVSAvoidease of mounting and dismounting
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The securing frame is designed to be movable relative to the base plate, transitioning between a retracted position for easy device insertion and a forward position where locking hooks engage to secure the device. This dynamic design provides both ease of operation during mounting and structural stability during use.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking hooks are pre-positioned on the securing frame so that when the frame is moved forward, the hooks automatically engage with the charging device in a preliminary locking action, securing the device before final tightening is required.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If multiple locking hooks are used to secure the charging device, then reliability of the connection is improved, but difficulty of assembly increases

Engineering Contradiction:
Improvereliability of connectionVSAvoiddifficulty of assembly
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The locking hooks are designed to be self-aligning and self-latching. When the securing frame is moved into position, the hooks automatically find and engage with their corresponding engagement points on the charging device, eliminating the need for precise manual alignment and reducing assembly difficulty while maintaining reliable connection.

Inventive Principle:
Principle #25Self-service
