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
1Productivity
If the battery capacity is increased to improve performance, then the battery size and mass increase, but the vibration resonance increases leading to distorted measurement results
Solution Approach 1:
A damping element is introduced as an intermediary component between the battery and the measurement device. This damping element absorbs vibrations generated by the battery, preventing them from reaching the measurement sensors. The damping element acts as a mediator that isolates the harmful vibrational effects while allowing the larger capacity battery to be used, thus resolving the contradiction between battery capacity and measurement precision.
2Object-affected harmful factors
If the battery mass is reduced to minimize vibration resonance, then the battery capacity is limited, but the overall performance of the vibration measurement device is reduced
Solution Approach 1:
The damping element serves as a mediator that allows the system to use a larger mass battery without suffering from increased vibration resonance. By placing the damping element between the battery and the measurement device, the harmful vibrations are absorbed before they can affect the measurement accuracy, thus enabling larger capacity batteries to be used while maintaining measurement quality.
3Stability of the object's composition
If mechanical locking features are used to secure the battery, then the battery is held in place, but tolerances and vibrational resonances of the internal structure are not eliminated
Solution Approach 1:
The damping element is introduced as an intermediary between the battery and the measurement device that goes beyond simple mechanical locking. While mechanical features provide positioning stability, the damping element additionally absorbs vibrational energy and eliminates resonances that mechanical locking alone cannot address, thus improving measurement precision while maintaining battery stability.
4Object-affected harmful factors
If allowable deviation in battery dimensions is reduced to minimize vibration resonance, then the vibration resonance is reduced, but the implementation cost increases
Solution Approach 1:
Instead of requiring tight manufacturing tolerances for the battery and internal structure, a damping element is introduced as a cost-effective intermediary solution. The damping element compensates for dimensional variations and tolerances in the battery and internal structure by absorbing vibrations, thereby achieving vibration resonance reduction without the need for expensive precision manufacturing.
