Solution Overview
Problem
Existing vibration measurement devices face challenges due to battery mass-induced vibration resonance, leading to distorted measurement results and reduced performance, and the use of larger capacity batteries is hindered by increased resonance, while mechanical locking features fail to eliminate vibrational resonances effectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the mass of the battery is increased to provide more capacity, then the battery capacity is improved, but the vibration resonance within the vibration measurement device increases
Solution Approach 1:
The patent applies damping material to convert the harmful vibration resonance generated by the battery mass into beneficial energy dissipation. The damping material absorbs and dissipates the vibrational energy, transforming the harmful resonance effect into a controlled energy dissipation process, thereby allowing larger capacity batteries to be used without compromising measurement accuracy.
2Object-generated harmful factors
If the allowable deviation in the dimensions of the battery and internal structure is reduced to minimize vibration resonance, then the vibration resonance is reduced, but the implementation cost increases
Solution Approach 1:
The patent changes the physical parameters of the system by introducing damping material with specific damping properties. Instead of relying solely on tight dimensional tolerances to control vibration, the solution modifies the energy dissipation characteristics of the system through the damping material's loss factor and damping coefficient, achieving vibration control through material property selection rather than manufacturing precision.
3Stability of the object's composition
If mechanical locking features are used to attach the battery to hold it in place, then the battery is secured, but the tolerances and vibrational resonances of the internal structure are not eliminated
Solution Approach 1:
The patent merges the mechanical locking function with the vibration damping function into a single integrated solution. The damping material serves dual purposes: it provides mechanical retention for the battery components while simultaneously absorbing vibration resonance. This combination eliminates the need for separate damping mechanisms and addresses both positioning stability and vibration control in one integrated approach.
