Connection Module Elastic Retaining Piece for Detection Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection modules face difficulties in preventing detection wires from coming away from narrow branch line paths due to limited space for wire locking mechanisms, making it challenging to maintain a secure routing configuration.
Innovation Solution
The connection module incorporates an elastic retaining piece on the path walls of the branch line path that can elastically deform to securely hold the detection wire, even when the path is narrow, and includes features like slits and tapered surfaces to enhance routing operability and prevent short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the branch line path is made narrow to increase compactness, then the connection module achieves higher compactness, but it becomes difficult to provide wire locking portions on opposite sides of the detection wire
Solution Approach 1:
Instead of making wire locking portions stand upright from the bottom of the branch line path (conventional approach), the patent inverts the approach by forming the wire locking portion as a protrusion on the side wall that extends toward the center of the branch line path. This inverted configuration allows the wire locking portion to be provided even in narrow paths where upright locking portions cannot fit.
Solution Approach 2:
The patent transitions from a two-dimensional bottom-view wire locking approach to a three-dimensional side-wall protrusion approach. The wire locking portion is formed as a protrusion extending from the side wall into the branch line path, utilizing the width dimension to create effective wire retention without requiring sufficient bottom space for traditional upright locking portions.
2Reliability
If wire locking portions are provided on opposite sides of the detection wire, then the detection wire is securely retained, but the configuration becomes complex when the branch line path is narrow
Solution Approach 1:
The patent merges the wire locking function into a single integrated protrusion structure formed on the side wall of the branch line path. Instead of requiring separate wire locking portions on both sides, the single protrusion combines the locking and guiding functions, achieving secure wire retention with a simpler configuration that is particularly effective in narrow paths.
Solution Approach 2:
The side-wall protrusion serves multiple functions simultaneously: it acts as a wire locking portion to prevent the detection wire from coming away, provides structural support for the narrow branch line path, and guides the wire into the correct position. This multi-functional design achieves reliable wire retention without increasing device complexity.
