Snap-Fit Holder Assembly That Prevents Device Scratching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holders for portable electronic devices cause scratching and affect the appearance of the devices during detachment due to rubbing against peripheral surfaces, and they also mar the aesthetic view from the front when clamping.
Innovation Solution
A holder designed for snap-fit assembly using a housing with a support frame and resilient elements, featuring catch members and push buttons to engage and disengage with retaining holes on the electronic device, preventing direct contact and allowing for secure attachment without scratching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping plates are used to grip the electronic device, then the holder can securely attach to the device, but the clamping plates will rub against peripheral surfaces during detachment causing scratches
Solution Approach 1:
The patent extracts the harmful clamping function from the attachment mechanism. Instead of using clamping plates that contact and rub against the device surface, the invention uses a snap-fit system where the holder is inserted into a recess and secured by resilient elements engaging retaining ribs. This separates the attachment function from surface contact, eliminating scratching while maintaining secure attachment.
Solution Approach 2:
The patent introduces an intermediary structure - the recess and retaining rib system - that mediates between the holder and the electronic device. The resilient elements engage with the retaining ribs formed by the surrounding wall of the recess, creating a secure connection without direct contact between the holder's attachment components and the device's peripheral surfaces, thus preventing scratches.
2Reliability
If clamping plates are used to hold the device, then secure attachment is achieved, but the appearance of the electronic device is adversely affected
Solution Approach 1:
The patent removes the visible clamping plates from the attachment mechanism. The holder attaches securely through snap-fit engagement within the recess, with no external clamping components visible on the device's peripheral surfaces. This maintains both secure attachment and clean appearance.
Solution Approach 2:
The holder is designed to be nested within the recess of the electronic device. The support frame fits into the recess space, and the resilient elements are received within the recess structure, allowing the attachment mechanism to be concealed within the device's housing rather than protruding outward, thus preserving appearance.
3Object-affected harmful factors
If a snap-fit mechanism with resilient elements is used, then rubbing against peripheral surfaces is prevented, but the holder structure becomes more complex
Solution Approach 1:
The resilient elements serve multiple functions: they provide the snapping action for attachment, maintain continuous contact pressure for secure holding, and enable easy release when force is applied. The retaining ribs formed by the surrounding wall serve both as structural support and as the engagement feature for the resilient elements, reducing the need for separate components.
Solution Approach 2:
The patent merges the attachment mechanism components into integrated structures. The retaining ribs are formed directly from the surrounding wall of the recess rather than being separate parts. The barrier plate and support frame work together as a unified attachment system, reducing the number of discrete components while achieving the snap-fit functionality.
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
The holder assembles securely without rubbing against the electronic device's surfaces during detachment, maintaining the device's appearance and allowing it to be hidden from view, thus preventing damage and enhancing aesthetics.
Implementation Method 1
The resilient element is disposed in the receiving space to provide the catch member with a restoring spring force.

AI summary
A holder is for holding an electronic device, and includes a housing, a support frame, and a resilient element. The housing is disposed on a rear face of the electronic device, defines a receiving space, and includes a barrier plate abutting against one side of the electronic device. The support frame is disposed in the receiving space and is movable relative to the housing. The support frame includes a catch member which is exposed from the housing, which is disposed opposite to the barrier plate, and which is engaged with a retaining hole in the rear face, and a push button portion exposed from the housing. The push button portion is operable to permit disengagement of the catch member from the retaining hole. The resilient element is disposed in the receiving space to provide the catch member with a restoring spring force.
