Sliding Portable Apparatus Keypad Mounting Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional widthwise sliding-type portable apparatuses have limited keypad mounting space due to the arrangement of keys and flexible circuits, leading to smaller key sizes and exposure to external environments, which causes deterioration.
Innovation Solution
A portable apparatus with a sliding device where the display unit and keypad unit slide up and down simultaneously, sharing excursion distance, and are semi-automatically opened and closed, featuring a fixing plate, connection frame, driving unit, and connection rotation unit to enable reverse sliding of the keypad unit in response to the display unit's sliding motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a sliding device is added to enable the keypad unit to slide automatically in reverse direction, then the keypad mounting space is increased, but the device complexity is increased
Solution Approach 1:
The connection rotation unit is integrated within the sliding device structure, with the rotation shaft positioned between the display unit and keypad unit. The connection frame and fixing plate are nested within the existing device housing, allowing the mechanism to achieve reverse sliding functionality without adding external protrusions or significantly increasing overall device complexity.
Solution Approach 2:
The connection rotation unit acts as an intermediary mechanism between the display unit and keypad unit. It includes a connection frame with a rotation shaft that mediates the sliding motion, enabling the keypad unit to move in reverse direction relative to the display unit while maintaining a compact integrated structure.
2Ease of manufacture
If the flexible circuit is directly exposed to external environment for connection, then the ease of manufacture is improved, but the reliability is deteriorated due to deterioration from external exposure
Solution Approach 1:
A protective cover is introduced to shield the flexible circuit from direct exposure to the external environment. The cover acts as a protective film that allows electrical connection functionality while preventing environmental factors such as moisture, dust, and oxidation from deteriorating the flexible circuit, thereby improving reliability without significantly complicating the manufacturing process.
