Adhesive Lanyard Substrate for Secure Device Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic devices, such as cell phones, are prone to damage and loss due to their susceptibility to drops and theft, and existing carrying methods do not provide adequate protection or security.
Innovation Solution
A flexible substrate with adhesive material and a lanyard is used to securely attach the device to a user's neck, allowing for easy carrying and protection, with the adhesive capable of withstanding significant shear force and the substrate being customizable in shape and configuration to accommodate device features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adhesive material is made very strong to prevent device removal, then security against theft and loss is improved, but the ease of attaching and detaching the device deteriorates
Solution Approach 1:
The adhesive is pre-applied to the substrate in a controlled manner during manufacturing, creating a strong bond that is difficult to remove but still allows intentional attachment. The adhesive is positioned and sized to provide secure attachment without requiring complex removal procedures.
Solution Approach 2:
The adhesive material is designed with specific physical and chemical parameters that optimize its bonding strength. By controlling factors such as adhesive composition, thickness, and curing characteristics, the material achieves high shear strength (1,000 grams at 72°F per ASTM D3654) while maintaining ease of application and removal.
2Adaptability or versatility
If the substrate is made thin and flexible for comfort and customization, then ease of operation and adaptability are improved, but the strength and durability against drops deteriorates
Solution Approach 1:
The substrate is constructed as a composite structure combining multiple materials with complementary properties. The base substrate provides flexibility and customization capability, while additional layers or reinforcements (such as the adhesive layer and protective covering) contribute strength and drop protection. This composite approach allows the substrate to be thin and flexible while maintaining adequate durability.
Solution Approach 2:
The substrate is designed as a flexible thin film or shell that can be customized in shape and configuration. This flexible substrate is combined with the adhesive layer and protective covering to create a composite structure that maintains flexibility and comfort while providing sufficient strength and durability through the combined layers.
3Reliability
If the adhesive layer is made thick and strong to withstand high shear forces, then reliability is improved, but the flexibility and ease of application deteriorates
Solution Approach 1:
The adhesive layer parameters (thickness, composition, curing characteristics) are precisely controlled to achieve the optimal balance. The adhesive is designed to provide high shear strength (1,000 grams at 72°F per ASTM D3654) while maintaining flexibility and ease of application. The adhesive layer thickness and properties are optimized to ensure strong bonding without compromising flexibility or application ease.
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 solution provides secure attachment and protection against drops and theft, allowing users to carry their devices safely and conveniently, with the ability to customize the substrate for specific device shapes and features.
Implementation Method 1
A layer of adhesive material is applied to at least a portion of the substrate first surface, and a protective layer of material is releasably secured to the adhesive material. When the protective layer is removed, the adhesive material is exposed such that the substrate can be secured to a housing of a hand held electronic device via the adhesive material.
Implementation Method 2
The lanyard allows for the substrate and an attached electronic device to be suspended around the neck of a user.

AI summary
An apparatus for carrying hand held electronic and other types of devices includes a flexible substrate and a lanyard secured to the substrate. The substrate has opposite first and second surfaces and opposite first and second end portions. A layer of adhesive material is applied to at least a portion of the substrate first surface, and a protective layer of material is releasably secured to the adhesive material. When the protective layer is removed, the adhesive material is exposed such that the substrate can be secured to a device via the adhesive material. The adhesive material is intended to securely attach the substrate to the device and such that removal therefrom is difficult. The lanyard allows for the substrate and an attached device to be suspended around the neck of a user.
