Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If harnesses are wired separately without integration structure, then wiring flexibility is improved, but reliability of wiring connection deteriorates due to potential detachment
Solution Approach 1:
The patent combines the harness integration structure with the insulation guide by forming the integration structure directly on the insulation guide. This merging ensures that the harness is securely held in place while the insulation guide simultaneously provides electrical insulation, preventing detachment and maintaining both reliability and flexibility.
Solution Approach 2:
The insulation guide acts as an intermediary component between the harness and the external environment. It provides both the integration function to secure the harness and the insulation function to prevent electrical contact with conductive surfaces, thereby improving wiring connection reliability without compromising flexibility.
2Reliability
If harnesses are integrated with wiring structure, then reliability of wiring connection is improved, but device complexity increases due to additional integration components
Solution Approach 1:
The patent merges the integration function and insulation function into a single component - the insulation guide. The integration structure is formed directly on the insulation guide, eliminating the need for separate integration components and reducing overall device complexity while maintaining wiring connection reliability.
Solution Approach 2:
The insulation guide is designed to perform multiple functions simultaneously: it provides electrical insulation, serves as the base for the integration structure, and directly secures the harness. This multi-functionality reduces the number of components needed and simplifies the overall wiring structure while ensuring reliable connections.
3Reliability
If separate wiring paths are used for primary and secondary power, then electrical insulation is improved, but manufacturing precision requirements increase due to path separation constraints
Solution Approach 1:
The patent segments the wiring structure into distinct first and second wiring paths on the insulation guide. These separate paths are specifically designed to prevent electrical contact between primary and secondary power harnesses, improving electrical insulation while the structured layout on the insulation guide helps manage positioning requirements.
Solution Approach 2:
The insulation guide provides a three-dimensional structure with raised portions and recesses that create physical separation between wiring paths. By utilizing vertical dimensionality rather than relying solely on planar positioning, the patent achieves electrical insulation between primary and secondary power paths while reducing the stringency of manufacturing precision requirements for path separation.

AI summary
A wiring structure for an electronic apparatus has a structure in which a first wiring path where a first harness that is used for transmitting a primary power is wired and a second wiring path where a second harness that is used for transmitting a secondary power is wired are formed, and a structure related to the first wiring path is formed so that, in a case where the first harness is wired, the first harness is integrated with the structure related to the first wiring path.
