Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws or adhesives are used to fix antenna modules, then the fixing strength is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The bracket structure is divided into multiple functional parts: a body, two retaining walls forming accommodating grooves, first stop parts, and second stop parts. This segmentation allows the antenna module to be precisely positioned and secured through the interaction of these discrete components, achieving strong fixation without requiring screws or adhesives.
Solution Approach 2:
The patent replaces traditional mechanical fastening systems (screws, adhesives) with a geometric interlocking mechanism. The accommodating grooves and stop parts create a mechanical constraint system that secures the antenna module through shape complementarity and spatial arrangement, enabling both strong fixation and easy assembly/disassembly.
2Reliability
If traditional fixing methods are used, then the antenna module is securely fixed, but the recyclability and environmental friendliness deteriorates
Solution Approach 1:
The bracket structure is designed to be easily disassembled and reused. The geometric interlocking mechanism allows the antenna module to be quickly removed and the bracket to be recovered for reuse, supporting recycling and sustainable manufacturing practices while maintaining reliable fixation during use.
3Ease of operation
If simple geometric structures are used, then the ease of assembly is improved, but the fixing stability deteriorates
Solution Approach 1:
The bracket structure employs asymmetric geometric features including the positioning of retaining walls at opposite ends, the arrangement of stop parts, and the configuration of accommodating grooves. This asymmetry creates a stable, interference-fit connection that prevents movement in all directions while maintaining simple assembly through straightforward insertion.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of the stop parts and accommodating grooves to achieve stable fixation. The stop parts extend in different directions to constrain the antenna module multiple dimensions, transforming a simple insertion action into a multi-directional constraint system that ensures stability.

AI summary
A bracket structure includes a body, two retaining walls, at least one first stop part, and at least one second stop part. The two retaining walls are respectively connected to two ends of the body, and respectively form an accommodating groove with the body, and a virtual connection line is extended between the two accommodating grooves. At least one first stop part protrudes from the body towards the virtual connection line. At least one second stop part protrudes from at least one of the two retaining walls towards the virtual connection line, and at least one first stop part and the at least one second stop part are separated by a clamping space in a direction. Thus, the bracket structure fix the antenna module without using any fixing components.
