Floating Branch Protector Jig for Wire Harness Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of manufacturing branch protectors for wire harnesses has poor workability due to the need to lift the branch protector main body above a jig base during tape winding and fastening band attachment, leading to inefficient assembly processes.
Innovation Solution
The method involves supporting the main component of the branch protector in a floating state on a jig pin erected on the jig base, allowing the lower space to be used as an assembly workspace, thereby improving workability by facilitating the assembly of the wire branch portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the branch protector main body is placed on a jig base for manufacturing, then the positioning and stability are improved, but the assembling workability deteriorates due to the need to lift the main body during tape winding and fastening band attachment
Solution Approach 1:
The manufacturing process is segmented into two distinct phases: a positioning phase where the main body is fixed on the jig base for stable component arrangement, and an assembling phase where the main body is lifted to provide working space for tape winding and fastening band attachment. This segmentation allows each phase to optimize for its specific requirement without compromise.
Solution Approach 2:
The state of the branch protector main body is made dynamic rather than static. The main body transitions from a fixed positioned state during manufacturing to a lifted working state during assembly operations. This dynamic adjustment enables the system to adapt to different operational requirements, maintaining both positioning stability and assembling workability.
2Ease of operation
If the main component is supported in a floating state on a jig pin, then the assembling workability is improved by providing workspace below, but the positioning stability may be compromised
Solution Approach 1:
The jig pin serves as an intermediary support element that enables the floating state of the main component. By supporting the main body at a specific point through the jig pin rather than allowing it to rest directly on the jig base, the system achieves both positioning stability and adequate workspace below for assembly operations.
