Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rubber or sponge materials are used for vibration absorption, then vibration absorbing effect is achieved, but manufacturing cost increases and materials deteriorate over time
Solution Approach 1:
The patent changes the material parameter from organic materials (rubber, sponge) to inorganic material (metal spring), transforming the vibration absorption mechanism from material damping to mechanical elastic deformation. This parameter change resolves the contradiction by providing both effective vibration absorption and resistance to deterioration while using cost-effective metal materials.
Solution Approach 2:
The patent creates a composite damping mechanism combining metal spring material with the speaker device structure. The metal spring works in conjunction with the speaker housing to form an integrated vibration absorption system that leverages the high durability and cost-effectiveness of metal while achieving the required vibration absorption performance.
2Strength
If screwing operation is used to fix speaker device to casing, then secure fixation is achieved, but manufacturing time and cost increase
Solution Approach 1:
The patent merges the vibration absorption function with the fixation function into a single integrated damping mechanism. The metal spring serves dual purposes: absorbing vibrations from the speaker and securing the speaker device to the casing. This merging eliminates the need for separate screwing operations and components, resolving the contradiction between fixation strength and manufacturing efficiency.
Solution Approach 2:
The damping mechanism is designed with multi-functionality, serving both as a vibration absorber and a fixation element. The metal spring's elastic properties enable it to provide both damping force and mechanical retention, allowing a single component to fulfill multiple functions that previously required separate elements and assembly steps.
3Strength
If additional screwing components are used to fix speaker device, then secure assembly is achieved, but manufacturing cost increases
Solution Approach 1:
The patent combines the fixation function into the damping mechanism itself, eliminating the need for separate screwing components. The metal spring structure provides both vibration absorption and mechanical retention through its elastic deformation characteristics, thereby reducing component count and manufacturing cost while maintaining assembly strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The damping mechanism effectively reduces noise by damping vibrations with resilient members like springs, preserving their elasticity and reducing manufacturing costs by eliminating the need for extra screws and costly materials.
Implementation Method 1
the resilient member is for resiliently abutting against the sleeve member, so as to absorb the vibration transmitted from the sleeve member as the main body generates the sound
Implementation Method 2
the sleeve member is for transmitting vibration generated by the main body as generating sound

AI summary
A speaker device with vibration absorbing function includes a main body and at least one damping mechanism. The main body is installed inside a first casing and a second casing for generating sound. The at least one damping mechanism is connected to the main body and includes a sheathing member, a sleeve member and a resilient member. The sheathing member is disposed on the first casing and located in a position near the main body. The sleeve member is connected to the main body and sheathes the sheathing member in a slidable manner for transmitting vibration generated by the main body as generating sound. Two ends of the resilient member are respectively installed inside the sheathing member and inside the sleeve member for resiliently abutting against the sleeve member, so as to absorb the vibration transmitted from the sleeve member as the main body generates sound.
