Motor Fixing Bracket Merging for Conveyance Seat Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power sliding apparatuses for conveyance seats require two additional brackets: a reinforcing bracket to prevent upper rail bending and a motor fixing bracket, which increases complexity and part count.
Innovation Solution
A power sliding apparatus where the motor fixing bracket serves both to fix the motor unit and close the opening for the gearbox, eliminating the need for a separate reinforcing bracket, and optionally integrates with another bracket to further reduce parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcing bracket is added to close the opening in the upper rail to prevent bending, then the structural strength is improved, but the device complexity increases due to requiring additional brackets
Solution Approach 1:
The motor fixing bracket is merged with the reinforcing bracket function, so that the motor fixing bracket simultaneously serves to fix the motor unit and close the opening in the upper rail to prevent bending, thereby eliminating the need for a separate reinforcing bracket
Solution Approach 2:
The motor fixing bracket is designed to perform multiple functions: fixing the motor unit to the upper rail and reinforcing the upper rail by closing the opening, making it a multi-functional component that reduces overall device complexity
2Reliability
If two separate brackets (reinforcing bracket and motor fixing bracket) are used, then the structural integrity is maintained, but the number of parts increases and assembly becomes more complex
Solution Approach 1:
The motor fixing bracket is merged with the reinforcing bracket function, so that the motor fixing bracket simultaneously serves to fix the motor unit and close the opening in the upper rail to prevent bending, thereby eliminating the need for a separate reinforcing bracket
Solution Approach 2:
The motor fixing bracket is designed to perform multiple functions: fixing the motor unit to the upper rail and reinforcing the upper rail by closing the opening, making it a multi-functional component that reduces overall device complexity
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
This configuration simplifies the apparatus by eliminating one or two brackets, reducing the number of parts and facilitating easier assembly, while maintaining structural integrity and functionality.
Implementation Method 1
a motor unit which is fixed to one of the right and left upper rails... When the rotational force of a motor constituting the motor unit is transmitted to the ball screws or the ball nuts
Implementation Method 2
ball screws or ball nuts attached to the lower rails or the upper rails. When the rotational force of a motor constituting the motor unit is transmitted to the ball screws or the ball nuts, the right and left upper rails slide relatively to the right and left lower rails

AI summary
In right and left upper rails in a power sliding apparatus of a conveyance seat, openings to receive gear boxes are formed, respectively. The gear boxes are attached to the right and left upper rails via the openings, respectively. The opening in one of the right and left upper rails is closed with a motor fixing bracket to fix a motor unit.
