Multifunctional Strap System for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cases and accessories for portable electronic devices do not effectively prevent accidental dropping or slipping, as they lack a secure mechanism to attach the device to a user's hand or a stable mounting option.
Innovation Solution
A strap system for portable electronic devices featuring a case with a detachable strap and clip configuration, allowing secure coupling to a user's hand and providing tension to prevent accidental drops, along with a middle portion that can act as a kickstand and card holder, and optional clips for additional stability and mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a basic plastic case is used to cover the portable electronic device, then the device is protected from damage, but the device can still be accidentally dropped or slipped from the user's hand
Solution Approach 1:
A strap is introduced as an intermediary element between the case and the user's hand. The strap is attached to the case at a first location and extends to a second location, allowing the user to secure the device to their hand or wrist, thereby preventing accidental drops while maintaining the protective function of the basic case.
Solution Approach 2:
The case is divided into functional segments: the main protective shell and the integrated strap system. The strap can be separately attached or detached from the case, allowing independent optimization of protection and handling functions. This segmentation enables the case to provide protection while the strap provides secure attachment.
2Ease of operation
If a strap is added to the case to prevent dropping, then handling stability is improved, but the case structure becomes more complex
Solution Approach 1:
The strap is merged with the case structure by integrating attachment points directly into the case design. The first and second locations for strap attachment are built into the case shell, combining the protective case and the securing strap system into a unified accessory that provides both protection and handling stability without requiring separate components.
3Reliability
If clips are added to the strap system for additional stability, then device security is improved, but the manufacturing complexity increases
Solution Approach 1:
Clips are pre-attached to the strap at specific locations during manufacturing. These clips can be easily engaged with corresponding features on the case or other surfaces, providing additional stability and mounting options without requiring complex assembly steps during product use. The preliminary attachment of clips simplifies the overall assembly process.

AI summary
A multifunctional strap system for portable electronic devices having a case and a strap on the back of the case. The case securely holds a protective electronic device while allowing access to all necessary features of the device. The strap securely couples a user's hand or other personal effects to the device. The strap may also be attached to a clip that removably attaches the strap to the bottom of the device. The detachable clip of the strap allows the strap system to loop around and be secured onto an object. The case may have an insert that can be used as a kickstand or a protective cover of a card held into place by the strap.
