Cellphone Attachment Cord with Elastic Coil and Adhesive Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellphone accessories fail to effectively prevent accidental drops and misplacement, as they do not provide a secure and convenient method for attaching the phone to clothing or accessories.
Innovation Solution
A cellphone attachment cord apparatus comprising a suspension clip, elastic coil, buckle, tether, and adhesive mounting card that allows secure attachment of a cellphone to clothing or accessories, using a selectively engageable buckle system and adhesive layer for easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure attachment method is used to prevent cellphone drops, then reliability is improved, but device complexity increases
Solution Approach 1:
The attachment apparatus is divided into multiple independent functional components: a suspension clip for attaching to clothing, an elastic coil for providing tension, a buckle for secure fastening, a tether for connection, and a mounting card with adhesive for phone attachment. This segmentation allows each component to perform its specific function efficiently while keeping the overall system manageable and relatively simple.
2Reliability
If a secure attachment method is used to prevent cellphone drops, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The attachment apparatus incorporates dynamic elements that enable easy operation. The elastic coil provides automatic tension and recoil, allowing the buckle to snap into and out of engagement easily. The adhesive mounting card allows for simple attachment to the phone case and clean removal without damage. These dynamic features ensure that while the attachment is secure during use, both attachment and detachment operations remain simple and quick.
3Reliability
If an elastic coil is used to provide tension, then reliability is improved, but loss of energy increases
Solution Approach 1:
The elastic coil operates through periodic action, storing and releasing mechanical energy in a cyclical manner. As the user moves, the coil alternates between extended and compressed states, providing continuous tension without permanent energy loss. This periodic operation allows the attachment to maintain reliability while minimizing energy dissipation, as the elastic potential energy is repeatedly converted to kinetic energy and back rather than being continuously lost.
