Solution Overview
Problem
Existing electronic shift control devices are complex in design, leading to increased size, weight, and manufacturing costs due to their intricate mechanical structures, which hinder space utilization and simplicity of operation.
Innovation Solution
The electronic shift control device incorporates a shift slider, shift body, and bracket with elastic members and a detent system, allowing for simplified assembly and operation by using a reduced number of parts, where the shift slider moves in a shift direction and returns to a reference position via elastic restoring forces, enabling easy selection of shift stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stick type electronic shift lever with complicated mechanical connection structure is used, then the shift stage can be changed, but the device becomes large and has poor space utilization
Solution Approach 1:
The device is divided into three main segmented components: shift slider (300), shift body (400), and bracket (200). Each component has a specific function and can be independently manufactured and assembled, reducing overall device volume while maintaining operational functionality.
Solution Approach 2:
The shift body (400) is disposed within the bracket (200), and the shift slider (300) operates within the shift body structure. This nested arrangement allows compact integration of components, minimizing the overall device footprint while preserving the shift stage selection function.
2Ease of operation
If a stick type electronic shift lever with complicated mechanical connection structure is used, then the shift stage can be changed, but the device becomes heavy and has complex assembly
Solution Approach 1:
The shift body (400) integrates multiple functional elements including the bullet seating part (420), hinge (430), and magnet seating part (440) into a single unified component. This merging reduces the total number of separate parts and simplifies assembly procedures while maintaining the electronic shift lever's operational capabilities.
Solution Approach 2:
The shift body (400) serves multiple functions: it houses the detent system components (bullet seating part), provides hinge movement (hinge), and accommodates the magnet for position sensing (magnet seating part). This multi-functionality reduces the need for separate components, thereby reducing device complexity and assembly complexity.
3Ease of operation
If traditional mechanical cable connection structure is used, then the shift lever has excellent operation feeling, but the device requires complicated mechanical connection structure
Solution Approach 1:
The patent replaces the traditional mechanical cable connection structure with an electronic system comprising a magnet (445) and sensor. The magnet is disposed in the magnet seating part (440) of the shift body, and its movement is detected by a sensor to determine shift stage position. This substitution eliminates complex mechanical linkages while preserving operational feedback and feeling through electronic sensing.

Function Achieved in This Case
The solution results in a compact, lightweight device with reduced manufacturing costs and simplified assembly, offering improved space utilization and user-friendly operation by utilizing a minimalistic design with elastic mechanisms for shift stage selection.
Implementation Method 1
the shift slider which has moved in the shift direction returns to the reference position by an elastic restoring force of the hinge elastic member
Implementation Method 2
The shift slider returns to the reference position by an elastic restoring force of the bullet elastic member after the shift stage is changed by moving the shift slider in the shift direction

AI summary
An electronic shift control device includes: a shift slider which is movable in a shift direction; a shift body under the shift slider and is movable according to the movement of the shift slider; and a bracket which is arranged under the shift slider and receives the shift body. The shift body includes elastic member receiving grooves and hinge protrusions. A hinge elastic member supporting the shift body is in the elastic member receiving groove. The bracket includes a hinge protrusion recess receiving the hinge protrusion. The shift slider is located at a reference position, and when the shift slider moves from the reference position in the shift direction, the hinge protrusion moves along the hinge protrusion recess, and a shift stage is changed, and the shift slider which has moved in the shift direction returns to the reference position by an elastic restoring force of the hinge elastic member.
