Solution Overview

Problem

Existing mobile phone holders in vehicles often damage the phone during crashes due to improper orientation and loading of the electrical contacts, leading to potential breakage and inability to use the phone for emergency calls.

Innovation Solution

A mobile phone holder with a push-push mechanism and a spring-loaded side element that securely positions the phone, preventing damage by compensating for thickness differences and reducing impact forces through cushioning, and allowing vertical insertion to minimize electrical contact stress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mobile phone is stored horizontally in the holder with electrical contacts aligned in the direction of travel, then the phone can be easily inserted and accessed, but the electrical contacts are subjected to high load during crashes causing breakage

Engineering Contradiction:

Improveease of insertionVSAvoidelectrical contact durability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent inverts the conventional horizontal insertion orientation by implementing vertical insertion of the mobile phone into the holder. This inversion changes the alignment of electrical contacts from horizontal (parallel to direction of travel) to vertical (perpendicular to direction of travel), thereby reducing the load on contacts during crashes while maintaining ease of insertion

Inventive Principle:

Principle #13The other way round (Inversion)

2Stability of the object's composition

If the mobile phone is secured tightly in the holder to prevent movement during driving, then the phone remains stable during normal operation, but the phone and passenger are damaged in the event of a crash due to acceleration forces

Engineering Contradiction:

Improvephone stabilityVSAvoidimpact damage

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent implements a cushioning element positioned between the mobile phone and the holder's backrest that activates during crashes. This cushioning element absorbs impact forces and reduces acceleration effects on the phone and passenger, while maintaining tight securing during normal driving operations through the push-push mechanism

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Strength

If a push-push mechanism is used to secure the mobile phone, then the phone is firmly held in place during driving, but the mechanism adds complexity to the holder structure

Engineering Contradiction:

Improveholding forceVSAvoidholder structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent segments the holding function into two independent mechanisms: a push-push mechanism for lateral securing and a spring-loaded cushioning element for longitudinal securing. This segmentation allows each mechanism to be optimized for its specific function while maintaining overall structural simplicity

Inventive Principle:

Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Ensures safe storage and functionality of the mobile phone during accidents, enabling emergency calls and reducing wear on electrical contacts by using a push-push mechanism and cushioning to absorb impact forces.

Implementation Method 1

the movable mobile phone holder (103) has a spring-loaded side element (118), which is designed conically in particular and adapts to an inserted mobile phone (121), so that the mobile phone holder (101) compensates for differences in thickness and achieves a fixed positioning

Methodology Applied

Scientific EffectElasticity: Elasticity

Implementation Method 2

the mobile phone tray (101) has a cushioning device with a first spring element (116), which is arranged such that in the event of a crash, the spring element (116) has a cushioning effect on the mobile phone (121) in a first direction of acceleration

Methodology Applied

Scientific EffectSpring cushioning: Spring
