Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auxiliary devices are limited in functionality and lack portability, making it difficult to maintain hygiene and prevent germ contact in public places, as they only serve a single purpose and are not versatile enough for modern portable electronic device usage.
Innovation Solution
A multi-purpose auxiliary device comprising a first body with a cone-shaped center pillar and a round head kit, allowing for capacitive or resistive LCD monitor operation and electronic credit card signature functionality, with a nanocomposite antibacterial fiber material for self-cleaning and antiviral protection, and a design that includes a sling for portability.

1Object-affected harmful factors
If a conventional auxiliary device is used to prevent hand contact with buttons, then hygiene protection is improved, but the device functionality remains monotonous and lacks versatility
Solution Approach 1:
The auxiliary device is designed to perform multiple functions: it can press physical buttons to prevent germ contact, operate capacitive touch screens when the round head kit is attached, and interface with resistive touch screens when the round head kit is removed. This multi-functionality transforms a single-purpose hygiene tool into a versatile interaction device that adapts to different screen types and operating contexts.
Solution Approach 2:
The device incorporates a removable round head kit that changes the device's operational characteristics. When attached, the kit enables capacitive touch screen operation; when removed, the device functions as a resistive stylus. This dynamic reconfiguration allows the same base device to adapt to different usage scenarios and screen technologies without requiring multiple separate tools.
2Adaptability or versatility
If the auxiliary device is designed with multiple functions for 3C products, then versatility is improved, but device complexity increases
Solution Approach 1:
The device is divided into two main segments: a base body containing the button-pressing functionality and a separate removable round head kit. This segmentation allows each component to be optimized for its specific function while keeping the overall system simple. The base body remains structurally straightforward, and the optional kit adds capability without permanently complicating the core device architecture.
Solution Approach 2:
The round head kit acts as an intermediary component that bridges the gap between physical button pressing and digital touch screen interaction. Rather than integrating complex touch screen technology directly into the base device, the patent uses this intermediate accessory to enable capacitive and resistive screen operation, thereby adding versatility without significantly increasing the complexity of the main device structure.
3Adaptability or versatility
If the center pillar head is made spherical for versatile operations, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies that the head of the center pillar should have a spherical shape with a diameter within the range of 2-5mm. By defining this specific parameter range, the invention balances versatility (sufficient size for various pressing operations) with manufacturability (achievable precision for spherical shaping). This parameter optimization allows standard manufacturing processes to produce the spherical head without requiring excessive precision while still achieving the desired multi-directional pressing capability.

AI summary
A multi-purpose auxiliary device includes: a first body having a holding portion and docking portion, a second body combined with the first body, and a round head kit sleeved on the first body. The docking portion has a semi-spherical enlarged portion having configurations for key operations. When the round head kit is sleeved on the center pillar of the enlarged portion, the first body serves as a capacitive stylus for operating an LCD monitor. When the round head kit is not sleeved on the center pillar, the first body serves as a resistive stylus for operating the LCD monitor, or serves as an electronic credit card signature by using an edge of the holding portion, thus providing versatility and frequency of use for the auxiliary device, and preventing effects of dirt or germs on hands.
