Multifunction Tape Wrapping for Protective Wire Harness Bundling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for an easy method to provide an exterior portion on a wire harness, as existing solutions often require additional protective members like sheets or tubes that are not easily applicable.
Innovation Solution
A wire harness with tape wrapped around it, where the tape-wrapping portions exhibit a binding function and additional functions such as protection against metal members, sound-proofing, and path regulation, allowing for the omission of external protective members like sheets or tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective members like sheets or tubes are provided on wire harness portions requiring high protection, then protective capability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines multiple functions into the binding tape itself. The tape not only binds wire bundles but also provides protective capabilities through its material properties (water resistance, oil resistance, durability). This eliminates the need for separate protective members like sheets or tubes, resolving the contradiction between protective capability and structural complexity
Solution Approach 2:
The binding tape is designed to perform multiple functions simultaneously: mechanical binding of wire bundles, protection against environmental factors (water, oil), and structural support. This multi-functionality allows a single component to replace what would traditionally require multiple separate protective members, thereby reducing device complexity while maintaining high reliability
2Reliability
If multiple separate protective members are used on wire harness, then protective capability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent merges binding and protection functions into a single tape application process. The binding tape is applied in one continuous operation, providing both mechanical binding and environmental protection simultaneously. This eliminates the need for multiple separate application steps required when using sheets or tubes, significantly improving ease of manufacture
Solution Approach 2:
The protective properties are built into the binding tape itself before application. The tape is pre-manufactured with water-resistant, oil-resistant, and durable materials, so no additional protective layers need to be applied afterward. This preliminary integration of protective capabilities simplifies the manufacturing process while ensuring reliable protection

AI summary
It is an object of the present invention to provide a technique with which an exterior portion can be easily provided on a wire harness. The wire harness includes: a wire; and one or more types of tape wrapped around the wire, a plurality of tape-wrapping portions being provided by wrapping the one or more types of tape around a plurality of portions along the longitudinal direction of the wire, and at least one tape-wrapping portion of the plurality of tape-wrapping portions exhibiting a binding function and an additional function different from the binding function.
