Electric Wire Fixing Device Projecting Piece Guide Binder Band
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric wire fixing devices in motor vehicle engine rooms face issues with poor storage performance and reduced workability due to unnecessary space creation and difficulty in assembling the binder band around the electric wires.
Innovation Solution
The electric wire fixing device incorporates a projecting piece between the side wall and bottom wall, paired with ribs and a cut-out portion, to guide the binder band and maintain the electric wires' position, preventing displacement and improving assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the binder band is wound around the electric wires to fix them close to the side wall, then the electric wires are securely fixed, but dead space is created between the fixed electric wires and the bottom wall, reducing storage performance
Solution Approach 1:
The invention introduces a rib structure that extends in the vertical dimension from the bottom wall, creating a new spatial dimension for wire placement. This allows wires to be positioned close to the side wall while maintaining adequate space from the bottom wall, effectively utilizing three-dimensional space rather than creating dead space in a two-dimensional plane.
Solution Approach 2:
The fixing structure is segmented into multiple functional elements: the bottom wall for initial wire placement, the rib for positioning and spacing, and the side wall with hole for final fixation. This segmentation allows each element to perform its specific function optimally, preventing wire displacement during assembly while maintaining storage space.
2Ease of manufacture
If space is provided between the ribs, connection portion and side wall for binder band passage, then the binder band can be passed through, but the tip end portion of the binder band may move towards the electric wire through the space, reducing assembling workability
Solution Approach 1:
The rib acts as an intermediary element between the bottom wall and the side wall. It provides a controlled passage path for the binder band tip end portion, guiding it through the assembly process without allowing unwanted movement towards the electric wire. The rib mediates between the need for passage space and the need for precise positioning.
Solution Approach 2:
The rib structure is pre-positioned during manufacturing to define the exact path and limits for binder band passage. This preliminary arrangement of the rib ensures that during assembly, the binder band tip end portion naturally follows the predetermined path without requiring additional guidance or adjustment, improving assembly ease.

AI summary
There is provide an electric wire fixing device improving storage performance of electric wires while preventing the electric wires from being displaced along a longitudinal direction of the electric wire. An electric wire fixing device 1 includes a bottom wall 14 at which an electric wire 7 is disposed and a pair of side walls 13, 15 extending from the bottom wall 14 to position the electric wire 7 between each other, one side wall 13 being provided with a hole 13a through which a fixation member 8 for fixing the electric wire 7 is passed. The fixation member 8 is passed through the hole 13a and wound around the electric wires 7 so that the electric wires 7 are placed close to the bottom wall 14 and fixed. The bottom wall 14 includes a projecting piece 16 extending from the bottom wall 14 and located between the electric wires 7 and the bottom wall 14, and the fixation member 8 is passed between the projecting piece 16 and the bottom wall 14.
