Stylus Pen Variable Length Storage for Rear Cover Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with a stylus pen storage recess on the rear surface compromise the appearance and limit material selection and design options for the rear cover and battery cover, restricting aesthetic and functional flexibility.
Innovation Solution
A stylus pen system with a variable length that can be stored without a separate separation recess in the housing, allowing the stylus to be easily retrieved without a recess, enabling various material and design applications for the rear cover and battery cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separation recess is formed on the rear surface of the housing to facilitate stylus pen removal, then the ease of operation is improved, but the appearance quality and design flexibility are degraded
Solution Approach 1:
The patent removes the separation recess from the rear surface of the housing and relocates the stylus pen storage function to a side surface slot. This extraction eliminates the aesthetic defect on the rear surface while preserving the storage and retrieval functionality through an alternative structural arrangement on the side surface.
Solution Approach 2:
The patent transitions the stylus pen storage and retrieval mechanism from a two-dimensional rear surface recess to a three-dimensional side surface slot structure. By moving the opening to the side surface and creating a slot that extends into the housing, the design achieves both aesthetic integrity and functional accessibility through spatial reconfiguration.
2Ease of operation
If a separation recess is formed on the rear surface of the housing, then the ease of operation is improved, but the adaptability of material selection and design options is reduced
Solution Approach 1:
By extracting the separation recess from the rear surface, the patent removes the constraint that limited material selection and design options. The rear cover can now be made from various materials and designs without being compromised by the presence of a recess, while the stylus pen storage function is maintained through the side surface slot.
3Shape
If the stylus pen is stored in a side surface slot without a separation recess, then the appearance quality is improved, but the ease of operation for separating the stylus pen is reduced
Solution Approach 1:
The patent incorporates a movable cap that can be pressed to automatically eject the stylus pen from the side surface slot. This preliminary action mechanism allows users to easily retrieve the stylus pen through a simple pressing motion, compensating for the lack of a traditional separation recess and maintaining ease of operation while preserving aesthetic quality.
