Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional iron-less linear motors face inefficiencies in heat dissipation and insulation due to increased current and voltage demands, leading to higher heat generation and a heightened risk of circuit shorts, as existing designs lack sufficient space for heat dissipating or insulation members.
Innovation Solution
The coil unit design incorporates continuously bent insulation wires with hollow portions and alternating coil units, featuring separation plates made of insulation or heat-conductive materials to enhance insulation and heat dissipation, respectively, and a connection member to secure these plates between adjacent vertical function sides, along with a heat dissipating member for improved ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If coil loops are arranged close to each other to reduce space, then volume is reduced, but heat dissipation efficiency deteriorates and circuit short risk increases
Solution Approach 1:
The coil unit is segmented by introducing separation plates that divide the internal space into distinct regions. These plates create gaps between adjacent coil loops, allowing heat to dissipate more effectively while maintaining electrical insulation. The segmentation transforms the dense coil arrangement into a structured configuration with intentional spacing for thermal and electrical management.
Solution Approach 2:
Separation plates serve as intermediary elements positioned between adjacent coil loops. These plates perform dual functions: providing thermal pathways for heat dissipation and maintaining electrical insulation to prevent circuit shorts. The intermediary structure enables close coil spacing for compactness while mediating the thermal and electrical interactions between coils.
2Power
If higher current and voltage are input to increase output and speed, then power is improved, but heat generation increases and efficiency reduces
Solution Approach 1:
The separation plates introduce local quality variations within the coil unit by creating regions with different thermal and electrical properties. The plates provide localized heat dissipation pathways and insulation zones, enabling the system to handle higher power inputs by managing heat generation at specific locations rather than uniformly throughout the coil assembly.
3Device complexity
If conventional coil design without separation plates is used, then device complexity is low, but insulation and heat dissipation capabilities are insufficient
Solution Approach 1:
The separation plates perform multiple functions simultaneously: they provide electrical insulation between coils, create thermal pathways for heat dissipation, maintain structural integrity of the coil assembly, and enable close spacing of coils for compactness. This multi-functionality increases reliability without proportionally increasing device complexity.

AI summary
A coil unit and coil assembly for iron-less liar motor and the coil unit includes two vertical function sides and two axial non-function sides. The multiple units are alternatively connected to each other by inserting the vertical function side of one coil unit into the hollow portion of the adjacent coil unit so as to form a coil assembly. The width of the vertical function side is D1 and the distance between two respective insides of the two vertical function sides is D2. D2=m×D1+ΔL, wherein m representing the number of the vertical function sides of other coil units received in the vertical direction of the hollow portion. The ΔL is the width of the gap which receives a separation plate between the two adjacent vertical function sides to increase the efficiency of dissipating heat or insulation when current passes through the coil assembly.
