Payment Console Speaker Hollow Area Acoustic Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic payment devices lack an effective audio broadcast function or have poor audio quality, negatively impacting user experience due to the development of mobile phone payments.
Innovation Solution
The electronic payment device incorporates a speaker housed in a console with a hollow area that enhances sound propagation, improving sound quality and volume, and includes a detachable material plate with two-dimensional code information for code scanning or face recognition payments, along with sensing apparatuses and light sources for user guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a speaker is added to the electronic payment device, then audio broadcast function is provided, but device complexity increases
Solution Approach 1:
The speaker is integrated into the housing structure of the electronic payment device, merging the audio output function with the existing device body. The speaker is disposed within the housing and faces the hollow area, combining multiple functions (payment processing, audio output, scanning) into a single integrated device rather than separate components.
Solution Approach 2:
The electronic payment device is designed as a multi-functional device that combines code scanning, face recognition, audio broadcast, and user interaction capabilities in one unit. The housing structure accommodates multiple components (speaker, camera, sensing apparatus, light source) that serve different functions, making the device universal for various payment methods.
2Reliability
If a hollow area is created in the housing to enhance sound propagation, then sound quality improves, but device volume increases
Solution Approach 1:
The hollow area is nested within the existing housing structure, utilizing the internal space efficiently. The speaker is disposed within the housing and faces the hollow area, creating a nested configuration where the audio enhancement feature is contained within the overall device volume rather than adding external bulk.
Solution Approach 2:
The hollow area creates a three-dimensional acoustic chamber within the housing, utilizing vertical and internal spatial dimensions rather than increasing the device's external footprint. The second sidewall extends obliquely to form the hollow area, using angular and spatial arrangement to achieve sound enhancement without proportional volume increase.
3Adaptability or versatility
If a detachable material plate is added for code scanning, then payment functionality is enhanced, but device complexity increases
Solution Approach 1:
The material plate is designed as a detachable component that can be separated from the housing, allowing independent replacement or maintenance. The extension part includes a recess configured to accommodate the material plate, enabling modular assembly where the plate can be removed and reattached without affecting the entire device structure.
Solution Approach 2:
The material plate transitions from a static fixed component to a dynamic detachable component that can be removed and reattached. This dynamic design allows flexibility in payment methods (code scanning, face recognition) and enables easy updates or replacements of the material plate without replacing the entire device.
