Expansion Unit Hook Mechanism for Tablet Rattle Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information equipment, such as tablet PCs, have limited functionality and lack secure attachment mechanisms for expansion units, leading to rattling issues due to their thin lateral design.
Innovation Solution
An expansion unit with a hook mechanism that engages with the tablet PC's engagement holes, utilizing levers and coil springs for stable attachment and detachment, ensuring secure connection without rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the tablet PC is designed with a thin lateral face for portability, then the portability is improved, but the attachment stability deteriorates causing rattling
Solution Approach 1:
The hook is designed to be movable in two directions: engagement direction (inserting into engagement hole) and pulling direction (pulling tablet PC toward expansion unit). This dynamic structure allows the hook to adapt to the thin lateral face of the tablet PC while maintaining stable attachment, resolving the contradiction between portability and attachment stability
Solution Approach 2:
The manipulation member acts as an intermediary mechanism that controls the hook's movement. By operating the manipulation member, the user can easily move the hook between engagement and non-engagement positions, providing a simple interface for achieving stable attachment without requiring direct manipulation of the hook itself
2Stability of the object's composition
If a secure attachment structure is implemented to prevent rattling, then the attachment stability is improved, but the device complexity increases
Solution Approach 1:
The attachment structure is segmented into distinct functional components: the hook (with engagement and pulling movements), the engagement hole (receiving the hook), and the manipulation member (controlling hook movement). This segmentation allows each component to perform its specific function simply, avoiding the need for a complex integrated mechanism while achieving stable attachment
Solution Approach 2:
The hook's dual-directional movability (engagement direction and pulling direction) provides a simple dynamic mechanism that achieves secure attachment without complex structures. The hook can insert into the engagement hole and then pull the tablet PC toward the expansion unit, creating a stable connection through straightforward mechanical movements rather than complex interlocking mechanisms

AI summary
An electronic device having a portable information equipment and an expansion unit is disclosed. The portable information equipment can be a tablet PC and the expansion unit is configured to expand a function of the tablet PC. The expansion unit includes an attachment part having a hook configured to be movable in an engagement direction from a non-engagement position to an engagement position, in the non-engagement position. The hook can be inserted into an engagement hole disposed at an attached part of the tablet PC in the engagement position. The hook can be further movable in a pulling direction of pulling the tablet PC towards the expansion unit 14, with the pulling direction being orthogonal to the engagement direction. A lever is utilized to move the hook in the engagement direction and in the pulling direction.
