Electronic Pen Side Attachment With Pressed Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic pens with side switches require time and effort to attach and detach, and the side switch protrudes prominently, which may not be preferred by all users. Additionally, there is a need for a more convenient way to change the side switch function based on user input methods.
Innovation Solution
The electronic pen features a cylindrical housing with a side opening that accommodates a side switch, using a side attachment member with an engagement part and a pressed part. A pressing mechanism part secures the side attachment member, allowing it to be easily attached and detached by inserting and pressing it into the side opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the side switch is secured with screws to the main body, then the attachment is secure, but it takes time and effort to attach and detach the side switch
Solution Approach 1:
The side switch operation part is divided into a separate detachable component that can be independently attached and removed from the main body, allowing quick changes without affecting other parts of the electronic pen
Solution Approach 2:
The attachment mechanism uses a combination of engagement protrusions and recesses at specific locations on the side switch and main body, providing secure attachment only where needed while keeping the rest of the structure simple and easy to assemble
2Ease of operation
If the side switch protrudes conspicuously from the main body, then it is easily accessible, but it may not be preferred by all users and affects the appearance
Solution Approach 1:
The side switch operation part can be dynamically adjusted in its position and projection distance from the main body, allowing users to configure it according to their preferences for both accessibility and appearance
Solution Approach 2:
The side attachment member serves multiple functions: it provides the side switch functionality, acts as a decorative cover, and can be configured in different positions to satisfy various user preferences for appearance and accessibility
3Device complexity
If a fixed side switch is provided, then the structure is simple, but the side switch function is seldom used depending on the application
Solution Approach 1:
The electronic pen is segmented into a main body and detachable side attachment members, allowing users to attach different types of side switches depending on the application, thereby increasing versatility without permanently complicating the structure
Solution Approach 2:
Different types of side attachment members are prepared in advance for different applications, and the appropriate one is attached before use, enabling the electronic pen to adapt to various functions without requiring complex reconfiguration during operation

AI summary
Provided is an electronic pen including a housing that is cylindrical and configured to incorporate an electronic pen function part that includes a circuit board. The housing has a side opening formed on a side surface of the housing. The side opening is configured to accommodate a side switch. The electronic pens also includes a side attachment member configured to be attached to the side opening of the housing. A first axial end of the side attachment member includes an engagement part that engages with the housing, and a second axial end of the side attachment member includes a pressed part. The housing incorporates a pressing mechanism part that presses the pressed part of the side attachment member attached to the side opening, toward the first axial end of the side attachment member.
