Solution Overview

Problem

Existing battery trays are single-function disposable structures that cannot be recycled and reused, and existing testing systems lack efficiency in simultaneously testing current, voltage, pressure, and temperature, leading to prolonged testing times and increased costs.

Innovation Solution

A battery tray with integrated signal collection portions for current, voltage, pressure, and temperature, along with a movable testing assembly and drive means, allows for synchronous testing and efficient battery transport, positioning, and connection, reducing testing time and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a battery tester is designed to accommodate multiple battery formats, then versatility is improved, but device complexity increases

Engineering Contradiction:
Improvebattery format compatibilityVSAvoidtester structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The battery tray is divided into multiple independent contact elements that can be independently configured. Each contact element can be selectively engaged or disengaged to match different battery terminal configurations, allowing the same tray to accommodate various battery formats without requiring multiple specialized trays or complex reconfiguration mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The battery tray is designed with universal adaptability to accommodate multiple battery formats (e.g., 9V, 18V, NIMH) through a single standardized interface. The contact elements are arranged and configured to provide universal compatibility across different battery types, eliminating the need for multiple specialized trays while maintaining simplicity in the overall tester structure.

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

2Productivity

If manual battery installation is used, then device complexity is reduced, but productivity decreases

Engineering Contradiction:
Improvebattery testing throughputVSAvoidautomatic insertion mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The battery tray and contact element assembly is designed to enable easy self-service battery installation. The spring-loaded contact elements automatically engage with battery terminals when the battery is placed in the tray, and the tray structure guides proper battery orientation and placement. This self-aligning, self-engaging mechanism eliminates the need for complex automatic insertion devices while significantly improving testing throughput by enabling rapid battery changes.

Inventive Principle:
Principle #25Self-service
