Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mobile device stands do not effectively secure wireless charging devices and prevent cable tangling or theft, while allowing hands-free operation and secure attachment to surfaces.

Innovation Solution

A mobile device stand with a rotatable housing and base that includes a stop guide and cable opening, allowing secure attachment to surfaces and preventing cable twisting, and optionally featuring a housing with an integrated wireless charging device and advertisement display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the housing is made rotatable to allow hands-free operation, then ease of operation is improved, but cable strain and tangling increase

Engineering Contradiction:

Improvehands-free operationVSAvoidcable strain

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cable opening is pre-positioned at the base rather than on the rotating housing, so the cable path is determined before rotation occurs. This preliminary positioning of the cable exit point prevents cable strain during rotation operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cable opening function is extracted from the rotating housing and placed on the stationary base. This separation removes the cable strain issue from the rotating component, allowing the housing to rotate freely without affecting cable tension.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If the housing is made rotatable for versatility, then adaptability is improved, but the charging device becomes vulnerable to theft

Engineering Contradiction:

Improverotation capabilityVSAvoidtheft prevention

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The stop guide protrusion and slot mechanism creates preliminary resistance to rotation at specific positions. This anti-action is built into the design to prevent unauthorized removal while still allowing controlled rotation for hands-free operation. The stop guide limits the rotation range and secures the charging device at predetermined angles.

Inventive Principle:

Principle #9Preliminary anti-action

3Reliability

If the housing is secured to the base with fasteners, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improveattachment securityVSAvoidfastener mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The attachment mechanism is segmented into two independent parts: the stop guide protrusion on the base and the corresponding slot on the housing. This segmentation allows each component to be simple in design while collectively providing secure attachment and rotation control without complex fastening mechanisms.

Inventive Principle:

Principle #1Segmentation

AI summary

A stand for a mobile device comprises a base and a housing. The base is configured to be affixed to a surface, and comprises a plate and a stop guide. The housing is configured to couple to the base. The housing defines a cavity, a receptacle configured to receive a wireless charging device, a recess configured to receive a portion of a cable of the wireless charging device, and a slot configured to receive the stop guide. The housing is movable relative to the base from a first position to a second position, whereby, when the housing is in the first position the stop guide is in a first portion of the slot, and when the housing is in the second position the stop guide is in a second portion of the slot.
