Vehicle Floor Protector for Wire Harness Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing floor arrangement of a vehicle's driver's section, where a wire harness is placed between acoustic absorbent segments, is prone to deformation and direct load application from the driver, leading to potential damage from repeated weight exposure.
Innovation Solution
A floor arrangement with a protector extending vertically from the floor frame, positioned on either side of the wire harness, receives and distributes the load applied by the driver, while maintaining easy access for maintenance and installation, and incorporates an acoustic absorbent-free space to prevent deformation and vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the wire harness is placed in a space between separated acoustic absorbent segments, then the floor mat deformation is prevented, but the acoustic absorbent is vulnerable to driver weight and direct load application
Solution Approach 1:
A floor protection member (reinforcing member) is introduced as an intermediary element between the floor mat and the wire harness. This mediator receives loads from the floor mat and transmits them to the floor frame, preventing direct load application to the wire harness while maintaining the space between acoustic absorbent segments that prevents floor mat deformation
Solution Approach 2:
The floor protection structure is segmented into distinct functional zones: acoustic absorbent segments for noise reduction, an acoustic absorbent-free space for wire harness placement, and a floor protection member for load bearing. This segmentation allows each component to perform its specific function without interfering with others
2Object-affected harmful factors
If the wire harness is placed between acoustic absorbent segments, then noise transmission is reduced, but the wire harness is exposed to repeated load application from driver movement
Solution Approach 1:
The floor protection member serves as a mediator that shields the wire harness from load application. It is positioned between the floor mat (which receives driver weight) and the wire harness (which needs protection), thereby preserving the noise-reducing configuration while protecting wire harness integrity
Solution Approach 2:
The floor protection member provides beforehand cushioning by being pre-installed in the floor structure to bear loads before they can reach the wire harness. This preventive measure ensures the wire harness is protected from repeated stress during driver movement and vehicle operation
3Reliability
If a protector is added to protect the wire harness, then the wire harness is protected from load, but the device complexity increases
Solution Approach 1:
The floor protection member is designed to perform multiple functions: it protects the wire harness from load, maintains the structural integrity of the floor, and works in conjunction with the acoustic absorbent segments. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity
Solution Approach 2:
The floor protection member is merged with the existing floor structure, integrating protection functionality into the conventional floor assembly. By combining the protection function with the existing structural elements rather than adding completely separate components, the increase in device complexity is minimized

AI summary
A floor arrangement of a driver's section of a vehicle includes a floor frame, an acoustic absorbent placed on the floor frame and a floor mat placed on the acoustic absorbent. A wire harness is placed in an acoustic absorbent-free space formed between the floor frame and the floor mat. A protector is provided inside the acoustic absorbent-free space in the vicinity of the wire harness and extends upward from the floor frame. This protector is affixed to the floor frame and configured to receive a load applied to the floor harness from the upper side thereof.
