Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The portable device accessory market faces challenges in providing stable holding solutions for portable devices while also accommodating the rapid release cycles of new devices and consumer demand for multifunctional products with innovative structures that can reduce volume when not in use and facilitate sales promotion.
Innovation Solution
A portable device holder with a band-shaped strap, a fixing plate, a closing plate, a movable plate, and an attachment mechanism that allows for stable device holding, promotional word display, and volume reduction by folding when not in use, featuring a strap pull-out part, a groove-shaped housing, and a rotatable movable plate for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the strap is made with a fixed structure to ensure stable holding, then the holding stability is improved, but the occupied volume cannot be reduced when not in use
Solution Approach 1:
The strap is designed with a movable plate that can change position relative to the fixing plate, allowing the strap to transition between an extended configuration for stable holding and a folded configuration for compact storage. The movable plate slides within guide grooves to enable this dynamic transformation while maintaining structural integrity.
Solution Approach 2:
The strap structure allows the movable plate to nest within the fixing plate when folded, with the movable plate containing guide grooves that receive the protruding plate of the fixing plate. This nesting arrangement enables compact storage while maintaining the full length of the strap for use.
2Ease of manufacture
If the strap structure is simplified to reduce manufacturing complexity, then the ease of manufacture is improved, but the functionality for both stable holding and volume reduction is compromised
Solution Approach 1:
The strap is divided into distinct functional components: a fixing plate with protruding elements, a movable plate with guide grooves, and hooking parts. This segmentation allows each component to be manufactured separately using simple processes while the assembled structure provides both stable holding and compact folding functionality.
Solution Approach 2:
The movable plate serves multiple functions: it guides the strap during folding, maintains structural integrity when extended for holding, and enables compact storage when folded. The guide grooves in the movable plate simultaneously provide structural support and define the folding path, eliminating the need for separate guiding mechanisms.
3Adaptability or versatility
If the central part of the strap is made protruded to display promotional words, then the sales promotion capability is improved, but the structural complexity increases
Solution Approach 1:
The central part of the strap is pre-configured with a protruding section that naturally displays promotional words when the strap is in use. This preliminary design ensures that the promotional message is automatically visible without requiring additional active components or complex mechanisms.
Solution Approach 2:
The promotional display function is merged with the structural component of the strap. The protruding central part that provides structural support and defines the folding geometry also serves as the display area for promotional words, eliminating the need for separate display mechanisms.

AI summary
Disclosed is a configuration of a portable device holder. The portable device holder according to the present invention includes: a strap, a fixing plate, a closing plate, a movable plate and an attachment means. The portable device holder is attached to the back side of the portable device so that the portable device can be more stably hold or installed, can display promotional words and phrases on the central part of the strap where the central part is protruded if pushing both side tip ends and thus, can be used for sales promotion, and further, can reduce the occupied volume by spreading the strap when not in use.
