Solution Overview

Problem

Existing battery pack fastening systems lack flexibility and have usage restrictions, making them inadequate for efficiently fastening and marking fasteners in battery packs of different models and specifications.

Innovation Solution

A battery pack fastening system comprising an operating platform, a fastening assembly, a driving assembly, and a control module, where the fastening assembly includes a fastening component, a marking component, and an image capture component, and the control module uses visual guides formed from images of the fasteners to precisely position and operate the fastening and marking components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If traditional automatic fastening devices are used, then fastening operation can be automated, but the system lacks flexibility and has many usage restrictions

Engineering Contradiction:
Improveautomation of fastening operationVSAvoidflexibility and usage restrictions
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The fastening assembly integrates multiple functions including fastening, marking, and image capture into a single device. The marking component can perform both marking and image capture operations, while the fastening component handles fastening operations. This multi-functional design allows the system to adapt to different battery pack models and specifications without requiring separate dedicated devices for each function.

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

Solution Approach 2:

The driving assembly enables dynamic positioning of the fastening assembly to any location on the battery pack surface. The system can dynamically adjust the position and orientation of the fastening component based on the detected fastener locations, making the automated system flexible enough to handle various battery pack configurations and fastener arrangements.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If fixed-position fastening devices are used, then device structure is simple, but they cannot adapt to different battery pack models and fastener positions

Engineering Contradiction:
Improvesimplicity of device structureVSAvoidadaptability to different models and positions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system replaces fixed mechanical positioning with vision-guided dynamic positioning. The image capture component detects fastener positions and the control module calculates the appropriate positioning, replacing the need for complex mechanical adjustment mechanisms while maintaining structural simplicity. The driving assembly executes the positioning based on visual feedback rather than mechanical pre-positioning.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-positioning by capturing images of the battery pack, detecting fastener locations automatically, and adjusting its own position accordingly. The marking component also serves dual purposes by both marking fasteners and capturing their positions for the control module to process, enabling the system to adapt to different configurations without external intervention.

Inventive Principle:
Principle #25Self-service
