Wire Holder for Image Forming Apparatus Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of wires connecting the power board and image forming unit in electrophotographic printers is cumbersome due to direct routing on the casing, making it difficult and confusing.
Innovation Solution
An image forming apparatus with a main frame, image forming unit, power board, and a detachable holder member that securely holds the wires connecting the power board and image forming unit, facilitating easy installation by routing them through a frame assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wires are routed directly on the casing, then the wire arrangement is simple, but the installation becomes confusing and difficult
Solution Approach 1:
The patent introduces a wire holder as an intermediary component between the casing and the wires. The wire holder is attached to the casing and provides designated slots or grooves that guide and secure the wires, making installation straightforward while maintaining a clean and organized appearance.
Solution Approach 2:
The wire holder is pre-attached to the casing before the wires are installed. This preliminary action creates a prepared pathway for the wires, eliminating the confusion of routing wires directly on the casing during installation and ensuring proper positioning from the start.
2Device complexity
If wires are laid out directly on the casing, then the structure is simple, but the positioning and securing of wires becomes difficult
Solution Approach 1:
The wire holder serves as a mediating structure that provides precise positioning features (such as slots, grooves, or recesses) for the wires. This intermediary component ensures accurate wire positioning without requiring complex direct integration into the casing structure.
Solution Approach 2:
The wire holder can be designed as a separate, modular component with distinct positioning features for different wires. This segmentation allows each wire to be precisely positioned and secured independently, improving manufacturing precision while keeping the overall structure relatively simple.
3Ease of operation
If wires are routed outside the casing, then accessibility is improved, but the routing and assembling procedures become confusing
Solution Approach 1:
The wire holder acts as an intermediary that facilitates easy wire accessibility while maintaining organized routing. By providing external mounting with designated wire paths, it allows workers to access and connect wires easily without the confusion of ad-hoc routing procedures.
Solution Approach 2:
The wire holder is pre-installed on the casing with predetermined wire pathways and connection points. This preliminary preparation eliminates the need for complex routing decisions during assembly, making the process straightforward while keeping wires accessible for connection.
