Solution Overview
Problem
Conventional shift by wire systems in vehicles require multiple shift locks to maintain the shifting stages, leading to inefficient space utilization and increased complexity.
Innovation Solution
An electronic shifting device with a simplified shift pattern utilizing a combination of linear paths, fixing points, and shift locks, where the operator moves along these paths to select shifting stages, and sensors and controllers manage the locks to prevent misoperation, reducing the number of shift locks needed.

Engineering Contradiction Analysis
1Reliability
If multiple shift locks are provided to maintain shifting stages, then the shifting operation can be controlled reliably, but the space utilization becomes inefficient and device complexity increases
Solution Approach 1:
The patent extracts and eliminates unnecessary shift locks from the system. By reconfiguring the shift pattern, the invention removes redundant locking mechanisms while maintaining reliable shifting control through the optimized path configuration that uses fewer locks more effectively.
Solution Approach 2:
The remaining shift locks are designed to serve multiple functions and multiple shifting stages. The reconfigured pattern allows each shift lock to control multiple stages along the optimized paths, increasing the utility of each locking mechanism and reducing the total number required.
2Reliability
If multiple shift locks are provided to maintain shifting stages, then the shifting operation can be controlled reliably, but the device complexity increases
Solution Approach 1:
The patent extracts and eliminates unnecessary shift locks from the system. By reconfiguring the shift pattern, the invention removes redundant locking mechanisms while maintaining reliable shifting control through the optimized path configuration that uses fewer locks more effectively.
Solution Approach 2:
The patent combines the functions of multiple shift locks into a smaller number of multi-functional locks. The reconfigured shift pattern integrates the locking control so that fewer locks manage multiple shifting stages, reducing overall device complexity.
3Ease of operation
If shift locks are arranged between respective shifting stages, then automatic return to Null stage can be implemented, but a large space is occupied
Solution Approach 1:
The patent changes the spatial arrangement of the shift pattern from a traditional layout to an optimized configuration with first and second linear paths. This dimensional reorganization allows shift locks to be positioned more efficiently, reducing the space required while maintaining the automatic return function through the new path geometry.
Solution Approach 2:
The shift pattern is segmented into distinct linear paths (first linear path with Null and N stages, second linear path with D and R stages). This segmentation allows each path to have its own optimized lock arrangement, reducing overall space requirements while maintaining functional independence of each shifting mode.

AI summary
An operation device of a shift by wire way excludes mechanical connection for transferring operational force between a transmission and an operation device for shifting, which can be used in a vehicle to which an electronic shifting device is mounted. For this purpose, a shift pattern is capable of operating intuitively a shifting device by providing a shift pattern identical to an existing shift pattern and keeping user's experience and at the same time reducing the number of the shift lock to solve the drawback of a prior shift pattern provided with a plurality of shift locks that defines the utilizing of a space, and thereby utilizing a space at a maximum level.
