Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in forming a high-voltage power supplying path efficiently and reducing size, as they often require complex internal wiring and additional space for power connections, which complicates maintenance and increases costs.
Innovation Solution
The apparatus features a conductive wire material forming a high-voltage power supplying path on the outer surface of the housing, which applies a pressing force to the transferring unit and positions it correctly, ensuring stable contact and reducing the need for internal wiring, thus enabling size reduction and cost optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supplying path is provided inside the housing, then the high-voltage power supply is stable, but the apparatus size increases and manufacturing becomes complex
Solution Approach 1:
The power supplying path is moved from the internal three-dimensional space to the external two-dimensional surface of the housing. The conductive wire material is disposed along the outer surface of the housing to form the power supplying path, allowing high-voltage power to be supplied to the imaging portion and transferring unit without occupying internal space, thus reducing apparatus size while maintaining power supply stability.
Solution Approach 2:
Instead of providing complex internal wiring, the patent uses a simple conductive wire material traced along the housing surface to create the power supplying path. This simplified representation of the power path reduces manufacturing complexity and apparatus size while maintaining the essential function of high-voltage power delivery.
2Reliability
If complex internal wiring is used for power supply, then power delivery is reliable, but maintenance difficulty and cost increase
Solution Approach 1:
The power supplying path is extracted from the internal wiring system and placed on the external housing surface. This allows the conductive wire material to be easily accessed, inspected, and replaced without disassembling the apparatus, significantly improving maintenance ease while maintaining power delivery reliability through the direct external connection.
3Reliability
If additional space is allocated for internal power connections, then power supply stability is ensured, but device complexity and cost increase
Solution Approach 1:
The housing surface serves multiple functions: it provides structural support, electrical insulation, and a pathway for the conductive wire material to form the power supplying path. This multi-functional use of the housing eliminates the need for separate internal power connection structures, reducing device complexity while ensuring power supply stability.
