Solution Overview

Problem

Users face inconvenience when removing a mobile phone from a traditional mobile phone box, as it often requires turning the box upside down, which is not ergonomic or efficient.

Innovation Solution

An accommodation structure with a base featuring a groove and an accommodating slot, where the groove's depth increases towards the slot, allowing the mobile terminal to be easily inserted and removed without flipping the base, with a peripheral part of the terminal protruding for easier grip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mobile terminal is placed flat in the base, then the base structure is simple, but the user must turn the base upside down to retrieve the terminal which is inconvenient

Engineering Contradiction:
Improveconvenience of terminal retrievalVSAvoidbase structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The groove is designed with varying depth in the vertical dimension, creating a three-dimensional accommodating slot that allows the terminal to protrude. This dimensional change enables the terminal to be accessed from the side rather than requiring inversion of the base, solving the retrieval convenience problem while maintaining overall structural simplicity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The base structure is segmented into different depth zones within the groove - a shallower region for stable placement and a deeper region creating the accommodating slot. This segmentation allows the terminal to be partially embedded while maintaining accessibility, resolving the contradiction between secure placement and easy retrieval.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the groove depth is uniform, then the manufacturing is simple, but the terminal cannot protrude for easy gripping

Engineering Contradiction:
Improvegrip accessibilityVSAvoidgroove manufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The groove is designed with non-uniform depth, creating a localized deeper accommodating slot at specific positions. This local quality change allows the terminal to protrude for easy gripping while keeping the overall groove structure relatively simple for manufacturing. The varying depth is concentrated in specific areas rather than requiring complex variation throughout the entire groove.

Inventive Principle:
Principle #3Local quality
