Battery Pack Concave Recess for Hinge Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in achieving a larger rotatable angle for the display housing while maintaining a thin and compact design, as the battery pack's structure restricts the rotation of the display unit, and the existing solutions often require additional components like stoppers or complex cable management.
Innovation Solution
The electronic apparatus incorporates a battery pack with a concave portion at its rear end, allowing the display housing to rotate further without contacting the main housing, and arranges cables in a direction crossing the thickness of the display housing to optimize space and reduce stress on the harness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the battery pack has a flat rear end structure, then the assembly is simple and manufacturing is easy, but the rotatable angle of the display housing is limited
Solution Approach 1:
The battery pack rear end transitions from a flat two-dimensional surface to a three-dimensional concave structure. The recess portion creates depth variation that actively accommodates the display housing during rotation, enabling a larger rotatable angle without adding external components or increasing overall device complexity.
2Length of moving object
If additional components like stoppers are added to increase rotatable angle, then the rotatable angle increases, but the device complexity and number of parts increase
Solution Approach 1:
The rotatable angle limiting function is merged into the battery pack structure itself through the concave recess design. Instead of separate stoppers or mechanical limits, the recess geometry inherently defines the rotation range by accommodating the display housing at specific angular positions, eliminating the need for additional components.
3Reliability
If cables are arranged parallel to the thickness direction of the display housing, then the cable management is simple, but the harness experiences higher stress and damage risk
Solution Approach 1:
The cable arrangement transitions from a one-dimensional parallel alignment to a two-dimensional crossing pattern. Cables extend in the longitudinal direction and cross the thickness direction at angles, distributing mechanical stress across multiple dimensions and reducing concentration on single cable paths, thereby improving durability without complex routing.
4Length of moving object
If the display housing rotation is restricted by the main housing, then the structural support is strong, but the rotatable angle is limited
Solution Approach 1:
The concave recess acts as an intermediary structure between the battery pack and display housing. It provides a dedicated accommodation space that guides and supports the display housing during rotation, maintaining structural integrity while enabling motion that would otherwise be restricted by direct contact with the main housing.
