Expandable Loop Accessory Holder with Bias Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for storing styluses or electronic pens with electronic devices are either cumbersome, aesthetically unsuitable, or insecure, often occupying valuable internal space and risking loss due to external storage.
Innovation Solution
An expandable loop accessory holder that can be coiled within the device's chassis when not in use, extending for easy access and securely holding the accessory with the aid of a bias member, such as a spiral spring, and a door mechanism to maintain the device's appearance and prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a slot or channel is used to store the accessory within the device chassis, then the accessory is securely held and integrated with the device, but valuable internal space is occupied
Solution Approach 1:
The accessory holder uses a movable door that can open and close, transitioning between a retracted position (when not in use) and an extended position (when the accessory needs to be accessed). This dynamic mechanism allows the holder to occupy minimal space when closed while providing secure storage when open, resolving the contradiction between security and space occupation.
Solution Approach 2:
The accessory holder is nested within the device chassis, with the door mechanism allowing the holder to be concealed within the chassis when not in use. The holder can be extended outward when needed, effectively nesting the storage function within the limited internal volume while maintaining secure accessory holding capability.
2Volume of stationary object
If an external storage method such as a stick-on or attachable loop is used, then internal space is preserved, but the method becomes cumbersome and may not hold the accessory securely
Solution Approach 1:
The accessory holder merges the benefits of internal integration and external accessibility by positioning the holder within the chassis while providing a door mechanism that allows secure accessory storage. The door can be opened to access the accessory and closed to secure it within the integrated structure, combining the security of internal storage with the accessibility of external interaction.
Solution Approach 2:
The movable door provides dynamic access to the accessory holder, allowing the user to open the door for accessory insertion/removal and close it for secure storage. This dynamic mechanism ensures the accessory is held securely when the door is closed while maintaining ease of access when needed, overcoming the limitations of static external storage methods.
3Volume of stationary object
If an external storage method is used, then internal space is preserved, but the device's appearance is compromised and contamination risk increases
Solution Approach 1:
The accessory holder is nested within the device chassis, concealed when the door is closed. This nesting approach maintains the device's clean appearance by hiding the accessory holder within the chassis structure, while the door mechanism provides controlled access when needed, preventing dust entry and maintaining aesthetic integrity.
Solution Approach 2:
The door acts as a protective barrier (shell) that can be closed to seal the accessory holder within the chassis, preventing dust and contamination from entering. When opened, it allows access to the accessory while maintaining the overall sealed environment of the device interior, thus protecting against harmful factors while enabling 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 solution provides a secure, space-efficient, and aesthetically integrated method for storing accessories, minimizing the risk of loss while maintaining the device's appearance and preventing dust entry.

AI summary
In an example, an accessory holder may include an expandable loop movable between a stowed position within a housing of a device chassis and a deployed position. When in the deployed position, the expandable loop may extend out of the housing to receive and hold a device accessory. The example accessory holder may further include a bias member to urge the expandable loop towards the stowed position.
