Modular Electronic Pen Housing for Independent Part Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic pens require replacement of the entire device when the outer casing or internal parts are damaged, leading to unnecessary discarding of functional components and reduced sustainability.
Innovation Solution
The electronic pen is designed with a modular structure comprising an electronic pen body portion unit and a power supply portion unit, housed in separate housing portions that can be coupled and replaced independently, allowing for repairability by replacing only the damaged part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electronic pen is designed with a unified structure where the functional section and power supply portion are electrically connected and housed together, then the device is compact and easy to manufacture, but the entire electronic pen must be replaced when any internal part is damaged, reducing repairability
Solution Approach 1:
The electronic pen is divided into two separable modules: a first module containing the functional section (signal transmission circuit, position detection sensor interface) and a second module containing the power supply portion (battery, power management circuit). These modules are electrically connected through contact portions that enable disconnection and reconnection, allowing independent replacement of each module based on its specific condition, thereby improving repairability while maintaining manufacturing simplicity.
2Device complexity
If the electronic pen is designed with a unified structure, then the device has simple construction, but functional components are discarded when the outer casing is damaged, reducing sustainability
Solution Approach 1:
By segmenting the electronic pen into replaceable functional module and power supply module, the invention enables selective replacement of only the damaged module rather than the entire device. This reduces component waste and improves sustainability while maintaining relatively simple construction through the use of modular components that connect via contact portions.
Solution Approach 2:
The modular design allows the functional module to be recovered and reused when only the power supply module is damaged, and vice versa. This prevents unnecessary discarding of functional components and promotes resource efficiency while maintaining simple device construction.
3Shape
If the functional section and power supply portion are integrated in one module, then the electronic pen has compact structure, but the power supply portion cannot be replaced independently when damaged
Solution Approach 1:
The electronic pen is segmented into two compact modules that are housed separately but electrically connected through contact portions. The first module contains the functional section and the second module contains the power supply portion. This segmentation enables independent replacement of each module while maintaining a compact overall structure, as each module is designed to fit within the limited space of the electronic pen housing.

AI summary
An electronic pen includes an electronic pen body portion unit, a power supply portion unit that supplies a power supply voltage to the electronic pen body portion unit, and a first housing portion and a second housing portion that form an electronic pen outer casing. The electronic pen body portion unit has a columnar shape, wherein a core body can be installed on one end side in the axial direction, and an electrical first terminal portion is included on another end side in the axial direction. The power supply portion unit includes a second terminal portion. In a columnar housing space of the electronic pen outer casing, the electronic pen body portion unit and the power supply portion unit are lined up and arranged in the axial direction to remain in position in the axial direction, and the first terminal portion and the second terminal portion are electrically connected.
