Electronic Control Bracket Asymmetry for Vibration Peak Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic control component brackets cause increased acceleration in specific frequency bands due to balanced support from identical elastic pieces, leading to high-speed vibrations.
Innovation Solution
The electronic control component bracket features elastic pieces with varying dimensions and asymmetrical pressing positions to intentionally create an imbalanced support configuration, dispersing acceleration peaks and reducing resonance in specific frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If identical elastic pieces are used to provide balanced support, then the electronic control component is stable, but acceleration peaks increase in specific frequency bands causing high-speed vibrations
Solution Approach 1:
The patent applies asymmetry by intentionally designing elastic pieces with different dimensions (different plate widths, plate lengths, or plate thicknesses) or by positioning them asymmetrically on the bottom portion. This asymmetric configuration prevents synchronized resonance in specific frequency bands, thereby reducing acceleration peaks while maintaining overall stability of the electronic control component.
2Ease of manufacture
If elastic pieces are made identical in dimensions and shape, then manufacturing is simplified, but resonance occurs in matching frequency bands increasing acceleration
Solution Approach 1:
The patent applies local quality by making variations in specific local characteristics of the elastic pieces (such as plate width, plate length, or plate thickness) while keeping the basic structure and material the same. This allows the components to be easily manufactured using standard processes while introducing local differences that prevent synchronized resonance and reduce acceleration peaks in specific frequency bands.
3Device complexity
If elastic pieces are arranged symmetrically, then the structure is balanced and easy to design, but acceleration peaks are concentrated in specific frequency bands
Solution Approach 1:
The patent deliberately breaks structural symmetry by arranging elastic pieces with different dimensions or in asymmetric positions on the bottom portion. This asymmetric arrangement disperses the resonance frequencies of individual elastic pieces, preventing concentration of acceleration peaks in specific frequency bands while maintaining reasonable design complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively suppresses excessive acceleration peaks, ensuring that the acceleration remains below a prescribed value by distributing vibration frequencies, thereby preventing high-speed vibrations.

AI summary
An electronic control component bracket includes a bottom portion on which a plurality of elastic pieces configured to press a lower surface of an electronic control component upward are provided, and abutting stop portions configured to abut, from above, against the electronic control component that is pressed upward. The plurality of elastic pieces are all the same, all in plate width, plate thickness, plate length, and plate shape. Pressing positions of the plurality of elastic pieces at which the elastic pieces press the lower surface of the electronic control component are arranged such that, when projected in a vertical direction relative to a plane orthogonal to the vertical direction, the plurality of elastic pieces do not have rotational symmetry and line symmetry on the plane of projection so that support for the electronic control component provided by the plurality of elastic pieces are made imbalanced.
