Antenna Connection Device with Curved Support for Load Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna connection devices require additional rubber stoppers for load dissipation, increasing production costs and complexity, and are unsuitable for automatic mass production due to difficult mounting and high defect rates.
Innovation Solution
The antenna connection device employs two tension parts and a curved support part to distribute deformation loads, eliminating the need for rubber stoppers and enhancing material durability, with a double structure that maintains continuous contact and reduces cracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rubber stoppers are added to dissipate external loads, then the reliability of load dissipation is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent removes the rubber stopper component entirely and extracts its load-dissipating function, integrating it instead into the support part's curved portion which naturally absorbs external loads through its geometric design
Solution Approach 2:
The load dissipation function previously performed by the separate rubber stopper is merged into the support part structure itself, specifically through the curved portion that dissipates loads through its shape and the interaction between tension parts
2Reliability
If rubber stoppers are mounted to maintain continuous contact, then the reliability is improved, but the productivity decreases due to difficult mounting and high defect rates
Solution Approach 1:
The patent eliminates the rubber stopper component and its associated mounting operations, extracting the component removal strategy to improve productivity while maintaining the continuous contact function through the integrated curved support structure
Solution Approach 2:
The support part's curved portion automatically maintains continuous contact and dissipates loads without requiring separate rubber stoppers or additional mounting operations, making the structure self-sufficient
3Device complexity
If a single tension part structure is used, then the device complexity is reduced, but the reliability decreases due to increased stress and material fatigability
Solution Approach 1:
The patent divides the tension-bearing function into two separate tension parts (first and second tension parts) that connect the support part to the fixing part at different locations, segmenting the stress path to reduce stress concentration and material fatigability in each individual tension part
4Strength
If fastening holes are formed in the main PCB and fastening pieces are used, then the connection strength is improved, but the manufacturing cost and process complexity increase
Solution Approach 1:
The patent merges the connection function into the antenna connection device itself through the fixing part with notches that engage with the PCB, eliminating the need for separate fastening pieces and fastening holes in the PCB, thereby simplifying the manufacturing process while maintaining connection strength
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces production costs, minimizes defective products, and ensures reliable load dissipation, improving the durability and reliability of the connection by distributing deformation loads effectively without the need for rubber stoppers.
Implementation Method 1
a curved portion which extends from an end of the flat portion to be bent in a direction opposite to the fixing part and is curved in a circular shape to be extended toward the first tension part... when an external deformation load is exerted on a connection portion, a short oblique portion of a free part comes into contact with a rubber stopper, thus relieving shocks
Implementation Method 2
two tension parts and a curved portion of a support part, thus obviating the necessity for a rubber stopper... when the end of the curved portion comes into contact with the fixing part in response to the deformation load, the deformation load is not effectively dissipated
