Horseshoe Hinge Frame Antenna for Metal Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern information handling systems, particularly those with metal chassis, locating antennas for wireless communication is challenging due to aesthetic design constraints such as narrow border bezels and smaller product dimensions, which limits the placement options and affects the efficiency of radiofrequency signal transmission and reception.
Innovation Solution
The integration of a horseshoe-shaped hinge frame antenna holder into the base chassis of information handling systems, utilizing the space occupied by a pivoting hinge structure, allows for the placement of antennas within a horseshoe-shaped hinge cavity, enabling efficient transmission and reception of radiofrequency signals while maintaining a compact design.

Engineering Contradiction Analysis
1Volume of moving object
If antennas are placed in traditional locations on metal chassis, then wireless communication function is provided, but aesthetic design constraints (narrow border bezels and smaller product dimensions) are violated and space is wasted
Solution Approach 1:
The patent combines the antenna structure with the hinge frame structure into an integrated assembly. The antenna is mounted within the hinge frame's horseshoe-shaped cavity, merging two previously separate components (antenna support structure and hinge mechanism) into a single integrated unit. This eliminates the need for separate antenna mounting space in the chassis, thereby reducing overall device volume while maintaining wireless communication functionality.
Solution Approach 2:
The antenna is nested within the horseshoe-shaped cavity of the hinge frame structure. The hinge frame's existing cavity space, which would otherwise be empty or require additional structural material, is utilized to house the antenna element. This nesting approach allows the antenna to occupy unused internal space within the hinge assembly, reducing the need for additional chassis volume.
2Reliability
If more space is allocated for antenna placement, then wireless signal transmission efficiency is improved, but the overall device size and metallic component quantity are reduced
Solution Approach 1:
The hinge frame structure serves multiple functions: it provides mechanical support for pivoting the display, houses the antenna within its horseshoe-shaped cavity, and maintains the device's aesthetic design. By making the hinge frame multi-functional, the patent eliminates the need for separate dedicated antenna mounting structures, thereby preserving metallic component quantity while ensuring adequate space for effective antenna operation.
3Ease of manufacture
If traditional antenna mounting structures are used, then antenna placement is simplified, but the chassis requires additional space and loses convertible laptop functionality
Solution Approach 1:
The patent merges the antenna mounting function with the hinge frame structure, which is already a critical component for convertible laptop functionality. The horseshoe-shaped cavity in the hinge frame naturally accommodates the antenna without interfering with the pivoting mechanism. This integration ensures that the same structural element serves both the mechanical pivoting function and the antenna support function, enabling convertible functionality while maintaining manufacturing simplicity.
