Solution Overview

Problem

The challenge in electric vehicle battery technology is the limited battery accommodating space due to structural constraints, which complicates the installation of multiple batteries and requires precise pre-tightening forces, making the process difficult and inefficient.

Innovation Solution

A battery container design featuring a bottom plate with opposing first and second fixing members, each with grooves that allow a clamp to enter and exit, facilitating the installation of multiple batteries by preventing interference and improving the convenience and efficiency of the installation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple batteries are installed in the battery container to maximize battery accommodating space, then the energy density and battery life of electric vehicles are improved, but the installation process becomes more difficult and complex

Engineering Contradiction:
Improvenumber of batteriesVSAvoidinstallation difficulty
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The fixing members are segmented with grooves that divide the clamping path into separate entry and exit routes. This segmentation allows the clamp to access batteries from different directions without interference, making it easier to install multiple batteries in the limited space of the battery container.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The grooves in the fixing members act as intermediaries that guide the clamp during installation. By providing dedicated pathways for clamp entry and exit, these grooves mediate between the clamp and the batteries, enabling smooth installation operations without direct interference between the clamp and fixing members.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If pre-tightening force is applied to batteries during installation to ensure proper reaction during charging and discharging, then the reliability of battery operation is improved, but the installation process becomes more complex and time-consuming

Engineering Contradiction:
Improvebattery operation reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fixing members with grooves are pre-configured to guide the clamp and automatically position batteries during installation. This preliminary structural arrangement ensures that pre-tightening force is applied correctly without requiring complex adjustment procedures, reducing installation time while maintaining reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The groove structure enables the fixing members to self-guide the clamp and self-position the batteries during installation. The design inherently provides the necessary guidance and positioning functions, eliminating the need for additional complex mechanisms or manual adjustments, thus reducing installation time while ensuring proper pre-tightening force application.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If the battery container structure is designed to accommodate maximum number of batteries, then the energy capacity is improved, but the device complexity increases due to interference between fixing members and installation tools

Engineering Contradiction:
Improvebattery capacityVSAvoidstructure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The fixing members with grooves serve multiple functions: they secure batteries, guide the clamp during installation, and prevent interference between the clamp and fixing members. This multi-functionality allows the structure to accommodate maximum batteries without increasing complexity, as the same structural elements perform multiple roles in the system.

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