Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If harnesses are directly bundled or mounted in spaces between vehicle components, then overall vehicle layout is rationalized, but harnesses produce friction with adjacent components during vibration, reducing service life
Solution Approach 1:
The patent introduces a harness fixing apparatus as an intermediary component between the harness and vehicle components. This fixing apparatus includes a fixing body with clamping structures that securely hold the harness, preventing direct contact and friction between the harness and adjacent vibrating components, thereby resolving the contradiction between layout efficiency and harness durability
Solution Approach 2:
The patent extracts the harness from its direct mounting position between vehicle components and relocates it to a dedicated fixing apparatus. This separation removes the harness from the harmful vibration environment of adjacent components while maintaining rational vehicle layout, solving the friction and wear problem
2Reliability
If harness fixing apparatus is applied to power battery harness, then harness protection is improved, but position of fixing apparatus relative to battery swapping electrical interface may affect inserting or pulling requirement and service life
Solution Approach 1:
The patent applies parameter optimization by determining specific distance ranges: the fixing apparatus should be positioned 5-15mm from the battery swapping electrical interface. This parameter optimization ensures both harness protection and proper operation of the electrical interface, resolving the contradiction between protection and operability
Solution Approach 2:
The patent performs preliminary testing and optimization to determine the optimal positioning parameters of the fixing apparatus before actual application. Through pre-testing of different positions, the optimal distance range (5-15mm) is established, ensuring both harness protection and electrical interface functionality are achieved

AI summary
Disclosed are a method and an apparatus for optimizing and testing a harness layout of a battery swapping electrical interface. The method includes: obtaining a first distance, a second distance and initial floating data of the battery swapping electrical interface; adjusting the first distance and the second distance to obtain first floating data of the battery swapping electrical interface again; repeatedly inserting or pulling the plug into or out of the socket of the battery swapping electrical interface; obtaining second floating data of the battery swapping electrical interface after repeatedly inserting or pulling the plug into or out of the socket for a preset number of times; and determining the current first distance and second distance as optimal distances if it is judged that the second floating data is in the second index interval.
