Bi-directional Sliding Portable Terminal Camera Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals with external camera lens modules risk loss or lens exposure to external environments, leading to image quality deterioration, while embedded modules face foreign material invasion.
Innovation Solution
A bi-directional sliding-type portable terminal design featuring a phone body with a first section for keys and a second section for a camera lens housing, where a bi-directional sliding body moves longitudinally to expose either the keys or the camera lens housing, protecting both from external conditions and allowing efficient camera use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external camera lens module is provided, then camera functionality is enabled, but the lens is exposed to external environment causing foreign material invasion and image quality deterioration
Solution Approach 1:
The patent implements a sliding body that can move between positions to dynamically expose or cover the camera lens. The sliding body transitions from a first position where the lens is exposed for photography to a second position where the lens is covered and protected, allowing the system to adapt between camera functionality and protection modes
Solution Approach 2:
The terminal is divided into distinct functional sections: a phone body with keys, a sliding body that can move independently, and a camera lens module. This segmentation allows the sliding body to selectively cover or expose the lens without affecting other components, resolving the contradiction between accessibility and protection
2Reliability
If an embedded camera lens module is provided, then the lens is protected from loss, but foreign materials can easily invade and deteriorate the lens
Solution Approach 1:
The sliding body provides dynamic control over lens exposure. When the sliding body is at the first position, the lens is exposed for camera operations. When moved to the second position, the lens is protected while maintaining secure integration with the terminal structure, preventing both loss and foreign material invasion
3Object-affected harmful factors
If a sliding body is introduced to protect the camera lens, then lens protection is improved, but device complexity increases
Solution Approach 1:
The sliding body serves multiple functions: it covers the camera lens for protection, exposes the lens for photography, and can be integrated with key mechanisms. This multi-functionality reduces the need for separate protective components, thereby limiting the increase in overall device complexity while achieving comprehensive lens protection

AI summary
Disclosed is a bi-directional sliding-type portable terminal. The bi-directional sliding-type portable terminal comprises a phone body and a bi-directional sliding body. The phone body comprises a first section which is located on one side of the top surface thereof and within which a plurality of keys are mounted, and a second section which is located on the other side of the top surface thereof spaced apart from the first section and within which a camera lens housing is mounted. The bi-directional sliding body linearly moves on the phone body in a longitudinal direction while facing the phone body, opens the first section to expose the keys by moving toward the second section, and opens the second section to expose the camera lens housing by moving toward the first section.
