Solution Overview

Problem

Conventional methods for securing batteries in electronic devices require manual operation, leading to potential battery loosening and damage if not properly fastened, and existing spring structures complicate battery removal.

Innovation Solution

An assembly structure with a slidably positioned fixing element, an elastic component, and a hook mechanism that automatically fastens the battery in place upon insertion, eliminating the need for manual operation and ensuring secure attachment without continuous pushing during removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a spring structure is used to automatically fasten the battery, then the battery is automatically secured without manual operation, but the user must continuously push the fixing element during battery removal which is inconvenient

Engineering Contradiction:

Improveautomatic fasteningVSAvoidbattery removal

Core Design Contradiction:

Extent of automationVSEase of operation

Solution Approach 1:

The fixing element is divided into two independent functional parts: a hook for engagement with the battery and an elastic component for providing restoring force. This segmentation allows the hook to remain engaged with the battery while the elastic component independently provides the force needed for automatic fastening, eliminating the need for continuous user intervention during removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The elastic component is pre-loaded with potential energy before the battery is inserted. When the battery is inserted, the fixing element automatically moves to engage the hook with the battery, and the pre-stored elastic energy automatically drives the fastening action without requiring user input during the critical fastening moment.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual operation is required to pull the fixing element, then the battery can be securely fastened, but the user may forget to fasten the battery leading to loosening and damage

Engineering Contradiction:

Improvebattery fasteningVSAvoidmanual fastening operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fixing element is designed to automatically perform the fastening function through the elastic component's restoring force. When the battery is inserted, the system self-activates to engage the hook with the battery and secure it in place, eliminating the need for user memory or manual intervention to achieve reliable fastening.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical operation of pulling the fixing element is replaced by an automatic mechanical system consisting of the elastic component and hook mechanism. The elastic component converts stored potential energy into kinetic energy to automatically drive the fixing element into the engaged position, replacing the need for user-applied force.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the fixing element is designed to automatically return to locked position, then battery security is improved, but the structure becomes more complex with additional components

Engineering Contradiction:

Improvebattery securityVSAvoidfixing mechanism structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fixing element merges two functions into a single integrated component: the hook for mechanical engagement with the battery and the elastic component for providing automatic restoring force. This merging reduces the need for separate actuators, sensors, or control mechanisms that would increase complexity, while still achieving reliable automatic fastening.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The elastic component is designed as a simple, inexpensive, replaceable element that provides the necessary restoring force through basic elastic deformation. This simple elastic element replaces complex mechanical springs, pneumatic systems, or electronic actuators, achieving reliable automatic return with minimal structural complexity.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A case with assembly structure includes a body, an engaging portion, a fixing element and an elastic element. The body has an accommodating slot and the engaging portion is disposed in the accommodating slot. The fixing element is slidably disposed on the main body and is located on one side of the accommodation slot and adjacent to the engaging portion. The fixing element has a hook. One end of the elastic element is disposed to the body and another end is disposed to the fixing element. The fixing element is moved between a fixed position and a release position along a first direction. When the fixing element is moved to the release position, the hook of the fixing element is moved along a second direction to hook the engaging portion. Meanwhile, the elastic element is made the fixing element be pulled toward the fixed position.
