Portable Terminal Strap With Folded Portion For Battery Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straps for portable terminals with large capacity battery packs inhibit smooth rotation when the battery pack protrudes, causing the strap to bend and press the rotation mechanism, preventing vertical and horizontal operation.
Innovation Solution
A strap design with a plate portion, rotation mechanism, grip portion, and folded portion that allows the strap to be mounted without bending, ensuring the rotation mechanism remains unobstructed, even with a large capacity battery pack, using a leather or cloth material with a central rotation axis and orthogonal folded portion to maintain flatness and enable free rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large capacity battery pack is mounted to the portable terminal, then the battery capacity is improved, but the battery pack protrudes and causes the strap to bend, inhibiting smooth rotation of the portable terminal
Solution Approach 1:
The strap is divided into multiple sections including a first strap, a second strap, and a folded portion. The folded portion acts as a separate flexible element that can bend independently to accommodate the protruding battery pack, preventing the rigid strap from pressing against the rotation mechanism and maintaining smooth rotation capability.
Solution Approach 2:
The strap design incorporates a folded portion that can dynamically change its shape and position. When the portable terminal is rotated or when the battery pack protrudes, the folded portion can bend and adjust accordingly, allowing the strap to adapt to different configurations without obstructing the rotation mechanism.
2Ease of manufacture
If the strap is mounted from above the portable terminal, then the strap can be attached to the terminal, but the strap surface bends and presses the rotation mechanism, inhibiting smooth rotation
Solution Approach 1:
The strap is segmented into a first strap portion that attaches to the portable terminal and a second strap portion that extends downward. The folded portion is positioned between these segments, allowing the attachment function to be maintained while the folded portion absorbs the bending stress caused by the protruding battery pack, preventing pressure on the rotation mechanism.
Solution Approach 2:
The folded portion acts as an intermediary element between the strap and the portable terminal body. It absorbs the mechanical stress and bending caused by the protruding battery pack, preventing this stress from being transmitted to the rotation mechanism, thus maintaining smooth rotation while still allowing the strap to be mounted from above.

AI summary
A strap used in a portable terminal includes a plate portion configured to be mounted on a surface of a main body of the portable terminal by attaching to a strap fixing portion of the main body, a rotation mechanism portion located at a substantially central portion of the plate portion and having a rotation axis located in a fourth area of the main body when the strap is mounted to the main body, a grip portion provided on the rotation mechanism portion, and a folded portion provided on the plate portion, and located at a position of a third area of the main body so as to be substantially orthogonal to a longitudinal direction, and to be bent in a direction toward the surface of the portable terminal when the strap is mounted to the main body.
