Solution Overview
Problem
Existing conveyance seats with speakers installed in the headrest have a complex structure, making it difficult to assemble the speakers and speaker assemblies, and there is a need for a simpler configuration.
Innovation Solution
A conveyance seat design with integrated right and left speaker holding portions and a connecting portion that forms part of the speaker assembly, eliminating the need for assembly bolts or additional plates, and allowing speakers to be accommodated in recesses exposed to the seat front side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speakers are installed in the headrest using a speaker assembly with separate holding portions and connecting plates, then the speakers can be securely held, but the structure becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent combines the right and left speaker holding portions into a single integrated holder structure, eliminating the need for separate connecting plates and assembly bolts. This merging of components simplifies the overall structure while maintaining the secure holding function for both speakers.
2Strength
If speakers are installed using multiple assembly components (holding portions, connecting plates, bolts), then the speakers can be firmly attached, but the number of components increases and assembly becomes more difficult
Solution Approach 1:
The patent merges multiple assembly components (holding portions, connecting plates, bolts) into a single integrated speaker holder that can be attached to the headrest as one unit, significantly simplifying the assembly process while maintaining firm attachment through the holder's design.
3Reliability
If separate assembly bolts and plates are used to connect speaker holding portions, then the speakers can be securely assembled, but the configuration of the speaker assembly becomes complex
Solution Approach 1:
The patent integrates the connecting function into the speaker holder itself, eliminating separate connecting plates and bolts. The holder is designed to securely assemble both speakers through its integrated structure, reducing configuration complexity while maintaining assembly reliability.
