Electronic Pen Side Switch Assembly With Detachable Pusher
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic pens face issues with unstable side switches due to potential misalignment or interference of terminals, and operators are difficult to remove for maintenance, compromising portability and functionality.
Innovation Solution
The electronic pen design includes a button switch and a pusher part with an operator that fits into an insertion part of the outer casing, ensuring stable operation and easy assembly/disassembly, with an overload absorption mechanism to prevent excessive pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator is attached to the casing of the ballpoint pen, then the side switch can be operated, but it is difficult to remove the operator from the casing once attached
Solution Approach 1:
The operator is divided into two separate parts: a main body that attaches to the casing and a detachable insertion part that fits into the operator opening. This segmentation allows the operator to be easily removed from the casing while maintaining stable operation during use, as the insertion part can be detached for maintenance without affecting the main body attachment.
2Ease of operation
If two terminals are disposed on the electronic pen body part with operator connection, then side switch function is realized, but the connection may be unstable due to positional shifts or dust interference
Solution Approach 1:
The insertion part acts as an intermediary component between the operator and the terminals. It provides a stable mechanical connection that compensates for positional shifts and prevents dust interference, ensuring reliable electrical connection while maintaining the side switch functionality.
3Length of moving object
If the electronic pen body part is reduced in size for portability, then it is easier to carry, but the structural complexity increases for maintaining functionality
Solution Approach 1:
The operator is nested within the outer casing, with the insertion part fitting into the operator opening formed in the casing. This nested structure allows the electronic pen to be reduced in size for improved portability while maintaining all necessary functional components without increasing overall structural complexity.

AI summary
Disclosed in an electronic pen that includes an electronic pen body part having a circuit substrate provided with a switch, an outer casing in which the electronic pen body part is housed, an operator provided on a side of the outer casing and positioned directly above the switch, a pusher part fitted into the operator, wherein the pusher part is between the switch and the operator, and an elastic body disposed on a rear end side of the electronic pen body part loaded into the outer casing, wherein the electronic pen body part, in operation, slides and moves in an axial direction of the electronic pen by the elastic body, and wherein the operator, in operation, is kept attached to the pusher part while the electronic pen body part slides and moves in the axial direction of the electronic pen.
