Sliding Device Tilting Mechanism for Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding devices for electronic apparatuses face challenges in achieving both user convenience and operability while ensuring a large exposed surface area and stability, particularly in full-flat type designs where the sub body part is accommodated in the main body part's plane, leading to complex operations and reduced visibility.
Innovation Solution
A sliding device with a mechanism that combines sliding and tilting operations, utilizing a sliding plate connected to intermediate sliders via columnar sliding pins and guide parts, with lock pins and stoppers to generate an assisting force for tilting, allowing the sub body part to automatically tilt and lock, simplifying the opening and closing sequence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the sub body part is accommodated in the main body part's plane (full-flat design), then the exposed surface area is increased, but the operation becomes complex and visibility is reduced
Solution Approach 1:
The patent combines the sliding operation and tilting operation into a single integrated mechanism. The sliding plate connects to intermediate sliders which are linked to the sub body part, so that when the sliding plate moves, it automatically causes the sub body part to tilt and lock. This merging of operations resolves the contradiction by maintaining the large exposed surface area of full-flat design while simplifying the user operation to a single sliding motion.
Solution Approach 2:
The mechanism is designed to automatically perform the tilting and locking operations without requiring separate user actions. As the sliding plate is moved by the user, the connecting mechanism self-actuates to tilt the sub body part and engage the lock pins with stoppers, making the system serve itself and reducing operational complexity.
2Stability of the object's composition
If the sliding plate is connected to the base plate through guides and rails, then the sliding operation is stable, but the device complexity increases
Solution Approach 1:
The patent divides the connecting mechanism into segmented components: the sliding plate, intermediate sliders, and guide parts are separated into distinct elements. Each component has a specific function - the sliding plate provides the sliding surface, the intermediate sliders transfer motion, and the guide parts provide stability. This segmentation maintains sliding stability while avoiding the complexity of a monolithic guide-rail system.
Solution Approach 2:
The intermediate sliders act as intermediary elements between the sliding plate and the sub body part. These sliders simplify the connection by providing a straightforward sliding interface while automatically converting the linear sliding motion into the tilting motion of the sub body part, reducing the need for complex direct coupling mechanisms.
3Ease of operation
If lock pins and stoppers are used to generate assisting force for tilting, then the tilting operation is simplified, but the manufacturing precision requirements increase
Solution Approach 1:
The lock pins and stoppers are designed to automatically engage and disengage based on the sliding plate's position, without requiring precise manual alignment or complex control systems. The geometry of the lock pins and stoppers is designed so that normal sliding motion naturally drives the engagement process, making the system self-regulating and reducing the need for high manufacturing precision while still providing reliable locking.

AI summary
The present invention relates to a sliding device for an electronic apparatus, and includes a contact piece projecting outward in a widthwise direction from a sliding plate and a contacted part with which the contact piece is caused to come into contact when the sliding plate is caused to slide with a maximum displacement in a rear direction relative to a base plate. The contact piece includes a partially cylindrical surface and a connecting surface. The contacted part includes a contacted shape part configured to be contacted by a boundary part of the partially cylindrical surface and the connecting surface to provide the sliding plate with a rotational force to cause a front direction end portion of the sliding plate to move in the bottom direction relative to a rear direction end portion of the sliding plate, and an engaged shape part with which the partially cylindrical surface and the connecting surface are caused to engage.
