Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hanging loudspeaker housings on walls is challenging due to the need for simultaneous mechanical and electrical connections, which are difficult to manage in limited spaces, and existing suspension systems lack stability and adjustment options, leading to potential misorientation and unauthorized adjustments.
Innovation Solution
A combination of a loudspeaker housing and a suspension bracket featuring complementary mechanical and electrical coupling devices, allowing for simultaneous mechanical and electrical connections during coupling, with adjustable orientations and secure locking to prevent accidental disengagement or unauthorized adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If mechanical connection is made first, then the structural stability is improved, but the ease of operation deteriorates due to limited space and difficulty in making electrical connection
Solution Approach 1:
The patent combines mechanical coupling and electrical connection into a single integrated operation. The electrical contacts are positioned such that they automatically engage when the mechanical coupling devices are brought together, eliminating the need for separate mechanical and electrical connection steps. This resolves the contradiction by making both connections simultaneously, improving ease of operation while maintaining structural stability.
Solution Approach 2:
The electrical contacts are pre-positioned and aligned on the coupling devices before installation. This preliminary arrangement ensures that when the mechanical coupling is performed, the electrical connections automatically engage without requiring additional manual manipulation, thus improving ease of operation while preserving structural integrity.
2Ease of operation
If electrical connection is made first, then the ease of operation is improved, but the reliability deteriorates due to wire length issues and safety risks
Solution Approach 1:
By merging mechanical coupling and electrical connection into a single simultaneous action, the patent eliminates the safety risks associated with making electrical connections first. The installer maintains control of the loudspeaker housing throughout the process, and no excessive wire length or unauthorized electrical exposure occurs, thus improving reliability while keeping the operation simple.
Solution Approach 2:
The electrical contacts are designed to automatically engage through their own positioning and alignment features when the mechanical coupling devices are brought together. This self-aligning mechanism eliminates the need for the installer to manually connect wires or deal with loose electrical connections, improving both safety and reliability.
3Adaptability or versatility
If ball and socket joint is used, then the adaptability is improved with unlimited adjustment possibilities, but the stability deteriorates due to orientation changes from vibrations and temperature fluctuations
Solution Approach 1:
The patent employs a hinge mechanism that provides controlled adjustability during installation, allowing the installer to position the coupling device at the desired angle. Once positioned, the hinge can be locked to maintain that orientation permanently. This dynamic approach combines the adaptability of adjustment with the stability of a fixed connection, resolving the contradiction between unlimited adjustment and orientation stability.
4Stability of the object's composition
If fixed bracket is used, then the stability is improved, but the adaptability deteriorates with limited adjustment possibilities
Solution Approach 1:
The hinge mechanism transitions from a fixed bracket by providing controlled movement capability during installation, then locks into a stable fixed position afterward. This allows the system to exhibit both adaptability (during positioning) and stability (after locking), resolving the contradiction between these two opposing requirements.
