Solution Overview

Problem

Existing phone attachment devices require permanent adhesives, making them difficult to remove and potentially leaving residue on phones or phone cases, and there is a lack of solutions for temporarily securing a handheld electronic device to a flat vertical surface without causing damage.

Innovation Solution

A removable hands-free phone-holding device with fasteners that allow for attachment to both a phone and various surfaces, using suction cups, adhesive fasteners, magnetic fasteners, or hook and loop fasteners, ensuring easy removal without residue.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If permanent adhesives are used to attach the phone to the surface, then the attachment strength is improved, but the ease of removal deteriorates and residue may be left on the phone

Engineering Contradiction:

Improveattachment strengthVSAvoidease of removal

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The attachment system is divided into two separate components: a reusable phone holder with permanent adhesive backing that attaches to the surface, and a removable phone case with corresponding adhesive that attaches to the phone. This segmentation allows the permanent adhesive to remain on the surface-mounted holder while the removable case can be easily detached from the phone without leaving residue.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The harmful residue-causing permanent adhesive is extracted from the phone-attachment interface and placed only on the surface-mounted holder. The phone case uses a removable adhesive that can be cleanly detached, separating the permanent bonding function from the removable attachment function.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If permanent adhesives are used to attach the phone to the surface, then the reliability of attachment is improved, but the harm to the phone surface (residue) increases

Engineering Contradiction:

Improveattachment reliabilityVSAvoidresidue on phone

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system segments the adhesive application into two parts: permanent adhesive on the surface-mounted holder for reliable attachment, and removable adhesive on the phone case that does not leave residue. This protects the phone surface from harmful residue while maintaining attachment reliability through the holder's permanent adhesive.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The surface-mounted phone holder acts as an intermediary between the permanent adhesive and the phone. The permanent adhesive bonds to the holder, not directly to the phone, allowing reliable attachment while preventing residue from contaminating the phone surface.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If a removable attachment mechanism is used instead of permanent adhesives, then the ease of removal is improved, but the attachment strength deteriorates

Engineering Contradiction:

Improveease of removalVSAvoidattachment strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The attachment system is segmented into a permanently mounted holder that provides strong attachment to the surface, and a removably attached phone case that provides easy removal from the phone. The strong attachment function is assigned to the holder-surface interface, while the easy removal function is assigned to the case-phone interface.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements dynamic attachment characteristics: the holder-surface connection is fixed and permanent for strong attachment, while the case-phone connection is temporary and removable for ease of operation. This dynamic differentiation resolves the contradiction between strength and ease of removal.

Inventive Principle:

Principle #15Dynamics
