Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lift mechanisms for heavy automotive components, such as electric vehicle batteries, lack the ability to accurately position and align the load for installation, requiring precise alignment of mechanical and electrical connectors during battery replacement.
Innovation Solution
A mobile lift apparatus with a powered lift mechanism, tiltable frame, and adjustable caster units that enable precise positioning and alignment of heavy loads, allowing for stable lifting and maneuverability, featuring a scissor linkage for vertical movement and tiltable load support platforms for angular adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile lift mechanism is used to support heavy automotive components, then mobility and versatility are improved, but positioning precision and alignment capability deteriorate
Solution Approach 1:
The load support platform is made tiltable and shiftable relative to the base frame, allowing dynamic adjustment of the platform's angle and position. The tilting mechanism enables the platform to rotate about a transverse axis, while the shifting mechanism allows lateral movement, providing adaptive positioning capability that resolves the contradiction between mobile versatility and positioning precision.
Solution Approach 2:
The lift mechanism is divided into independent functional modules: a mobile base frame with casters for mobility, a powered lift mechanism for vertical movement, and a separately controllable tiltable load support platform for precise positioning. This segmentation allows each module to optimize its function without compromising the others, enabling both high mobility and precise alignment.
2Measurement precision
If the load support platform is made tiltable for alignment, then positioning capability is improved, but device complexity increases
Solution Approach 1:
A tilting mechanism acts as an intermediary between the mobile base frame and the load support platform, providing the necessary angular adjustment capability. This intermediary component enables precise alignment of heavy loads without requiring complex reconfiguration of the entire lift system, thereby achieving improved positioning with controlled complexity.
3Measurement precision
If caster units are made adjustable for precise positioning, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The height adjustment function of the caster units is merged with the base frame's mobility function. The casters are integrated into the base frame corners, and their height adjustment capability is combined with the overall platform positioning system, reducing the need for separate complex adjustment mechanisms while maintaining precise positioning capability.
