Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acoustic speakers with curved surfaces face challenges in mounting and adapting protective parts due to their complex design, which are specific to particular acoustic configurations, making customization difficult and requiring complete redesigns when configurations change.
Innovation Solution
A protective part with a side and end protective portion, guided by a positioning device using magnets and pins, allows easy assembly and adaptation to different acoustic configurations by covering various box portions and featuring holes for sound output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If protective parts are designed with curved surfaces to match capsule-shaped speakers, then aesthetic appearance is improved, but mounting and dismounting complexity increases
Solution Approach 1:
The protective part is divided into multiple segments (first protective part, second protective part, third protective part) that can be assembled in a modular fashion. Each segment has corresponding convex and concave surfaces that interlock, allowing the complex curved shape to be constructed from simpler components that are easier to mount and dismount individually.
Solution Approach 2:
The patent introduces a new dimension of assembly by using multiple protective parts arranged in sequence around the capsule, rather than using a single monolithic cover. This dimensional approach transforms the mounting process from attaching one large complex piece to assembling several smaller segments, reducing operational complexity.
2Reliability
If protective parts are designed for very particular acoustic configurations, then acoustic performance is optimized, but adaptability to other configurations is reduced
Solution Approach 1:
The protective part design incorporates universal features through its segmented structure and standardized connection interfaces (convex-concave surface pairs). This allows the same basic protective part design to be adapted to different acoustic configurations by repositioning or reconfiguring the segments, rather than requiring completely different designs for each configuration.
Solution Approach 2:
The patent enables dynamic reconfiguration of the protective parts to match different acoustic configurations. The modular segments can be rearranged, added, or removed based on the specific loudspeaker arrangement, allowing the protective covering to adapt dynamically to various configurations while maintaining acoustic performance.
3Reliability
If protective parts are completely redesigned for each acoustic configuration change, then acoustic performance is optimized, but manufacturing time and cost increase
Solution Approach 1:
By segmenting the protective part design into standardized modular components, the patent eliminates the need to completely redesign protective parts for each acoustic configuration. Manufacturers can produce a limited set of standardized protective segments that can be combined in different arrangements, significantly reducing manufacturing time and cost while maintaining optimized acoustic performance for each configuration.
Solution Approach 2:
The patent allows for parameter changes in the configuration and arrangement of protective segments rather than changing the fundamental design. By modifying parameters such as the number, position, and arrangement of standardized segments, manufacturers can adapt to different acoustic configurations using the same base components, improving productivity while maintaining acoustic optimization.
