Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic devices require two batteries, but their battery start structure is not ergonomically designed, making it difficult for users to intuitively unlock both batteries simultaneously with their hands facing each other.

Innovation Solution

A battery fold structure with movable structures and bidirectional blocking elements allows users to unlock two batteries on the same surface by moving them in a bidirectional manner, enabling easy access and mounting of batteries in any compartment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional battery structure is used, then two batteries are required for standard equipment, but the battery start structure is not ergonomically designed and users cannot intuitively unlock both batteries simultaneously

Engineering Contradiction:

Improveergonomic operationVSAvoidbattery start structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent inverts the conventional battery operation approach by enabling bidirectional unlocking from both ends of the battery pack simultaneously. Instead of requiring sequential operation from one end, the movable structure allows both batteries to be unlocked at the same time by pushing from either end, making the operation ergonomic and intuitive for two-handed use.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The battery pack is segmented into multiple battery compartments with independent movable structures for each battery. This segmentation allows each battery to have its own unlocking mechanism that can be operated independently or simultaneously, enabling the ergonomic bidirectional operation while maintaining the two-battery configuration.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If fixed battery compartments are used, then battery mounting position is restricted, but flexibility in battery placement is reduced

Engineering Contradiction:

Improvebattery placement flexibilityVSAvoidbattery compartment structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The battery compartments are designed with universal compatibility through standardized movable structures and blocking elements. Any battery can be mounted in any compartment because the blocking elements and movable structures are configured to work with any battery position, providing placement flexibility without requiring complex custom-fit mechanisms for each compartment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A battery fold structure of an electronic device includes a device proper and at least one battery. The device proper has battery compartments and movable structures corresponding in position thereto, respectively. Each movable structure is movable relative to the device proper. At least one blocker is fixedly disposed at each movable structure. At least one bidirectional blocking element is fixedly disposed on the battery. The bidirectional blocking element has a first blocking portion and a second blocking portion. When the battery is received in one of the battery compartments, the first blocking portion of the bidirectional blocking element fixedly disposed on the battery is blocked by the blockers. When the battery is received in the other battery compartment, the second blocking portion of the bidirectional blocking element fixedly disposed on the battery is blocked by the blockers. Two batteries are mounted inside two battery compartments interchangeably and unlocked simultaneously.
