Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of external amplifiers in vehicles requires significant mounting space, complex mounting structures, and increased costs due to the need for custom brackets, which complicates assembly and can lead to interference with surrounding vehicle parts and quality issues with connector coupling.
Innovation Solution
An amplifier docking audio system that integrates a full digital amplifier within the vehicle's audio body, using a docking connector and sensor to connect and control external amplifiers, reducing the need for separate mounting spaces and structures, and allowing for flexible channel extension without the need for additional brackets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external amplifiers are installed separately from the head unit, then high-quality audio output and multi-channel support are achieved, but mounting space requirements and structural complexity increase
Solution Approach 1:
The patent integrates the external amplifier into the head unit by providing a docking space within the head unit body and a docking connector on the printed circuit board. The amplifier includes a corresponding docking structure that couples with the head unit's docking connector, merging the amplifier and head unit into a single integrated assembly. This eliminates the need for separate mounting brackets and complex installation structures while maintaining multi-channel audio output capability.
2Reliability
If custom mounting brackets are designed for external amplifiers, then installation stability is improved, but development costs and manufacturing complexity increase
Solution Approach 1:
The mounting function is merged into the head unit structure itself. The docking space is formed within the head unit body, and the docking connector is integrated on the printed circuit board. The amplifier's docking structure couples directly with these built-in features, eliminating the need for separate mounting brackets. This integration reduces development costs and manufacturing complexity while ensuring stable installation.
3Area of stationary object
If amplifiers are installed in limited vehicle spaces, then space utilization is improved, but interference with surrounding vehicle parts occurs
Solution Approach 1:
The amplifier is nested within the head unit structure. The docking space is formed inside the head unit body, allowing the amplifier to be housed within the existing audio system footprint. This nesting arrangement utilizes the available space efficiently while isolating the amplifier from surrounding vehicle parts, preventing interference with seats, wiring, and other components.
4Reliability
If separate installation structures are used for external amplifiers, then amplifier stability is improved, but assembly time and labor costs increase
Solution Approach 1:
The amplifier and head unit are merged into a single docking assembly. The amplifier's docking structure couples with the head unit's docking connector and docking space, creating a stable integrated installation. This eliminates the need for separate mounting brackets and complex assembly procedures, significantly reducing assembly time and labor costs while maintaining amplifier stability through the integrated docking mechanism.
