Flexible Socket and Sliding Cable Housing for Protected Transmitters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmitter devices with cable-connected sensors are prone to damage from mechanical loads and pressures, particularly from external sources like lawn movers, leading to potential failure of plug connections and cables.
Innovation Solution
The transmitter device features a housing with a channel for slidably receiving the cable, a flexible socket coupled outside the housing, and a cover with integral ribs for enhanced strength, along with watertight seals to protect against mechanical loads and liquid ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cable is directly connected to the housing, then the structure is simple, but the cable and plug connection are prone to damage from mechanical loads
Solution Approach 1:
The housing is segmented into an upper housing and a lower housing that are rotatably connected. This allows the sensor to be positioned in the lower housing while the cable connection point is separated in the upper housing, reducing direct transmission of mechanical loads to the cable connection.
Solution Approach 2:
A cable guide structure is introduced as an intermediary element between the cable and the housing. This guide structure includes a guide hole and guide surface that constrain and protect the cable, preventing direct contact with mechanical loads while maintaining electrical connection.
2Ease of operation
If the socket is disposed outside the housing, then the cable has more movement freedom, but the socket is more exposed to external damage
Solution Approach 1:
The socket is nested within the upper housing structure, which itself is part of the overall housing assembly. The cable passes through the upper housing to reach the socket, providing protection while maintaining movement freedom through the rotatable connection between upper and lower housings.
Solution Approach 2:
The upper housing acts as an intermediary protective structure between the external environment and the socket. It shields the socket from direct external damage while allowing cable movement through the rotatable joint mechanism.
3Reliability
If the sensor is covered by a cover, then the sensor is protected, but the cover adds structural complexity
Solution Approach 1:
The cover is merged with the upper housing structure, forming an integrated protective assembly. This reduces the number of separate components while maintaining protection functionality, as the upper housing itself provides structural protection when closed.
Solution Approach 2:
The upper housing serves multiple functions: it provides structural support, houses the cable connection point, and when closed with the cover, provides sensor protection. This multi-functionality reduces the need for separate dedicated protective components.
