Sliding Door Controller Unit Segmentation for Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door controller devices for vehicles are complex, heavy, and costly due to their intricate link structures, leading to manufacturing challenges and frequent malfunctions, as well as difficulties in maintenance.
Innovation Solution
A simplified sliding door controller device design that eliminates complex linkages by directly connecting the inside handle to levers, using a cable system to release latches, and separating actuators for enhanced design freedom and maintenance, including a safety lock release actuator to manage locking states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple rods and levers are joined to the remote controller to connect various devices, then the sliding door can be controlled to open and close, but the structure becomes complicated and heavy
Solution Approach 1:
The patent divides the remote controller into multiple independent actuators (first actuator, second actuator, third actuator) that can be separately disposed and maintained. Each actuator controls a specific function (latch lock release, hold open latch release, safety lock release), eliminating the need for a complex integrated link structure while maintaining full control functionality.
Solution Approach 2:
The patent extracts the actuator components from the traditional remote controller and separates them into independent units disposed at different locations. This extraction eliminates the complicated link structure by removing the central化的 control mechanism while preserving the control functions through distributed actuators.
2Ease of operation
If multiple rods and levers are joined to the remote controller, then the sliding door can be controlled, but the weight increases
Solution Approach 1:
By segmenting the remote controller into separate actuators disposed at different locations, the patent eliminates the need for heavy connecting rods and levers. Each actuator is a lightweight component that can be independently positioned, significantly reducing the overall weight compared to a traditional integrated remote controller with multiple linkages.
3Ease of operation
If a complicated link structure is used in the remote controller, then the sliding door can be controlled, but manufacturing time and cost increase
Solution Approach 1:
The patent segments the remote controller into independent actuators that can be manufactured separately and assembled in different locations. This eliminates the need for complex linkage mechanisms that require precise manufacturing and assembly, significantly reducing manufacturing time and cost while maintaining full control functionality.
4Ease of operation
If a complicated link structure is used in the remote controller, then the sliding door can be controlled, but maintenance and repair become difficult
Solution Approach 1:
By dividing the remote controller into separate, independently disposed actuators, the patent enables easy maintenance and repair. If one actuator malfunctions, only that specific component needs to be accessed and replaced, rather than disassembling a complex linked structure. This segmentation dramatically improves ease of repair while maintaining full control functionality.

AI summary
A sliding door controller device may include an inside handle disposed inside a sliding door; a hold open latch release lever disposed to rotate around a hinge, having a first bent portion formed outside the hinge, and disposed to rotate to one side around the hinge by the first bent portion pushed by the inside handle; and an inside handle lever disposed to rotate around the hinge, having a second bent portion formed outside the hinge, and disposed to rotate to the other side around the hinge by the second bent portion pushed by the inside handle.
