Solution Overview

Problem

Existing electronic devices, such as electronic payment terminals, face difficulties in battery extraction due to the small size and location of batteries, requiring tools that can damage the battery or its location, and users may lack necessary tools, leading to delayed battery changes.

Innovation Solution

A removable hatch with protrusions, acting as both a closure mechanism and a tool, allows for the release and pivoting of batteries from their slots, enabling easy extraction without external tools, by leveraging a 'leg' or 'hook' protrusion to release and pivot the battery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate tool (screwdriver, wrench, or pen) is used to remove the battery, then the battery can be extracted, but the risk of damaging the battery or its housing increases

Engineering Contradiction:
Improvebattery extractionVSAvoiddamage risk to battery
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The hatch is designed to combine two separate functions into one component: it serves both as the closure for the battery compartment and as the extraction tool for the battery. The protrusion on the hatch acts as an integrated lever that can be used to pry out the battery, eliminating the need for separate tools and reducing damage risk.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hatch serves itself by having its own protrusion that can be used to extract the battery. The structure of the hatch includes a built-in extraction mechanism that allows it to perform the battery removal function without requiring external tools, making the system self-sufficient.

Inventive Principle:
Principle #25Self-service

2Device complexity

If no tool is provided with the device, then the device structure remains simple, but users cannot extract the battery without external tools

Engineering Contradiction:
Improvedevice structureVSAvoidbattery extraction
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The hatch combines the closure function and extraction tool function into a single component, avoiding the need for separate tools while maintaining simple device structure. The protrusion on the hatch serves dual purposes: sealing the compartment when closed and leveraging the battery for extraction when opened.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hatch is designed as a multi-functional component that performs both as a closure element and as a battery extraction tool. The same hatch structure that seals the battery compartment also contains the protrusion that can be used to pry out the battery, making one component serve multiple purposes.

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

3Reliability

If the battery location provides robust retention areas, then the battery is securely held, but more retaining areas must be freed to extract the battery

Engineering Contradiction:
Improvebattery retentionVSAvoidextraction mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The hatch protrusion is designed to simultaneously interact with multiple retention areas during the extraction process. By positioning the protrusion to engage with both retention areas, the hatch can free up multiple retaining points in a single motion, simplifying the extraction mechanism while maintaining robust battery retention.

Inventive Principle:
Principle #5Merging (Combining)
