Solution Overview

Problem

Conventional battery boxes are limited in operation modes and convenience, with a design that can lead to damage and reduced service life due to improper lid opening and waterproofness issues, and lack flexibility in power supply options.

Innovation Solution

A battery box design featuring a detachable lid with a waterproof ring, a joining mechanism for rotation, a locking mechanism for secure closure, a power source assembly with a circuit board and external-connection cable, and USB connectors for multiple power source options, enhancing usability and waterproofness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the lid is pivotally connected to the box body, then the lid can be opened and closed, but the pivot shaft assembly is damaged or deformed due to concentrated force, impairing waterproofness and service life

Engineering Contradiction:
Improvelid opening and closing operationVSAvoidpivot shaft assembly durability and waterproofness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The lid connection mechanism is divided into two separate functional components: a joining mechanism for attachment/detachment and a locking mechanism for securing. This segmentation eliminates the pivot shaft assembly that concentrated force and caused damage, while maintaining lid operability through alternative means.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using a pivot shaft that rotates within the housing (conventional approach), the patent inverts the approach by having the lid detachably connect to the housing and rotate about an axis defined by the joining mechanism on the lateral side. This inversion moves the rotation axis away from the housing structure, eliminating force concentration on the housing pivot shaft.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If a conventional single-purpose battery box design is used, then the structure is simple, but the operation modes are limited and convenience is reduced

Engineering Contradiction:
Improvepower supply options and operation modesVSAvoidbox structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The battery box is designed with multi-functionality by incorporating both a power supply unit (battery compartment) and an external connection cable with USB interface. This allows the box to serve multiple purposes: storing batteries, providing wired power connection, and potentially charging mobile devices, thereby increasing adaptability without proportionally increasing complexity.

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

Solution Approach 2:

An external connection cable with USB connector serves as an intermediary component that bridges the battery box and external power sources or devices. This mediator enables flexible power supply options and expanded functionality while keeping the core box structure relatively simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If force is improperly applied to the pivotally connected lid, then the pivot shaft assembly is damaged, but proper force application requires user knowledge and care

Engineering Contradiction:
Improvepivot shaft assembly integrityVSAvoidlid operation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connection mechanism is segmented into joining and locking functions, with the locking mechanism providing a clear visual and tactile indicator when properly engaged. This segmentation makes the operation more intuitive and reduces the risk of improper force application, as users can easily identify the correct closed position.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking mechanism automatically engages when the lid is closed, providing self-verifying feedback to the user. This self-service feature ensures proper engagement without requiring user knowledge or careful force application, as the mechanism itself confirms when correctly positioned.

Inventive Principle:
Principle #25Self-service

AI summary

A battery box includes a box body composed of a housing and a lid. The box body has two opposite lateral sides provided respectively with a joining mechanism and a locking mechanism. A power source assembly is received in the box body and includes a circuit board, a power supply unit, and an external-connection cable. The joining mechanism allows the lid to be connected to the housing in a detachable and rotatable manner. The battery box can be switched to an operation mode that allows connection to an external power source device so as to adapt to modern application environments and provide more, and more convenient, operation modes.
