Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual wire splicing is used for dashboard conversion, then wiring flexibility is improved, but installation time and error rate increase
Solution Approach 1:
The wire harness is pre-assembled with all wires pre-connected to terminals and connectors before installation. This preliminary preparation eliminates the need for on-site wire splicing and connection work, significantly reducing installation time while maintaining wiring flexibility through the pre-configured harness design
Solution Approach 2:
The wire harness is designed as a segmented, modular unit with distinct sections for different wiring functions. This segmentation allows the entire harness to be installed as one piece rather than assembling individual wires on-site, reducing installation time while preserving the adaptability of individual wire segments within the harness
2Adaptability or versatility
If manual wire splicing is used for dashboard conversion, then wiring customization is improved, but installation complexity and error rate increase
Solution Approach 1:
All wiring configurations and connections are pre-customized during manufacturing of the wire harness. The harness arrives ready-to-install with all connections pre-made, eliminating complex on-site wiring customization work while maintaining the ability to accommodate different dashboard configurations through varied harness designs
Solution Approach 2:
The pre-assembled wire harness acts as an intermediary component that bridges the dashboard and vehicle wiring system. It consolidates all necessary connections into a single integrated unit, simplifying the installation process while maintaining customization capability through different harness configurations for different vehicle types
3Manufacturing precision
If extensive wiring knowledge is required, then installation precision is improved, but ease of operation decreases
Solution Approach 1:
The wire harness is designed to be self-installing with features like pre-attached connectors, color-coded wires, and plug-and-play interfaces. These self-service design elements guide the installer through the process without requiring extensive wiring knowledge, while still achieving precise connections through the pre-engineered harness structure
Solution Approach 2:
Wires and connectors use color-coding systems to identify functions and connections. This visual guidance system eliminates the need for installers to interpret complex wiring diagrams or understand electrical principles, making installation easy while ensuring precision through the standardized color-coded connection scheme
4Stability of the object's composition
If reversible installation is implemented, then vehicle component integrity is improved, but installation process complexity increases
Solution Approach 1:
The wire harness uses dynamic, reversible connection methods such as plug-and-play connectors and snap-fit mounting. These connections can be easily made and removed without damage, preserving vehicle component integrity while the standardized connector designs keep the installation process simple despite the reversibility requirement
