Lifter Device Compact Design via Component Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifter devices face challenges in maintaining a compact size due to the increasing complexity and size of components such as motors, controllers, and battery packs.
Innovation Solution
A lifter device design that incorporates a pole, a lifting member, a motor, a controller, a case to house the motor and controller, a transmission mechanism, and a battery mounting portion on the case, which concentrates the power and control components, thereby maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor, controller, and battery mounting portion are accommodated within the case, then the lifter device is restrained from increasing in size, but the device complexity increases due to integration requirements
Solution Approach 1:
The patent applies merging by integrating the motor, controller, and battery mounting portion into a single case structure. This consolidation reduces the overall device volume by eliminating separate housings and mounting structures, while the modular internal arrangement manages the complexity through functional grouping of components within the unified case.
2Length of stationary object
If the case is fixed to the pole to accommodate power and control components, then cable length is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The case is pre-designed with integrated mounting features and component positions that are established during case manufacturing. This preliminary action allows the motor, controller, and battery mounting portion to be positioned accurately within the case before the case is fixed to the pole, thereby reducing the precision requirements for the final fixation process while maintaining short cable lengths.

AI summary
A lifter device includes a pole, a lifting member guided by the pole, a motor that generates power used for ascending and descending of the lifting member, a controller that controls the motor, a case that is fixed to at least a portion of the pole and accommodates the motor and the controller, a transmission mechanism that transmits the power of the motor to the lifting member, and a battery mounting portion that is provided on the case and to which a battery pack is mouted to supply power to the motor.
