Head-Mounted Display Hinge Wire Routing for Stable Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted display apparatuses suffer from unstable electrical connections due to the conducting wire fracturing at the joint between the glasses frame and legs, primarily caused by pulling during rotation.
Innovation Solution
The head-mounted display apparatus incorporates a limiting member with a conducting wire trough defined by the third and first limiting parts, allowing the conducting wire to rotate within a confined space, preventing fracture and ensuring stable electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conducting wire is routed through the joint part between the glasses leg and the glasses frame, then the electrical connection can be established, but the conducting wire is prone to fracture due to pulling during rotation
Solution Approach 1:
The patent divides the conducting wire routing into separate segments: one segment runs through the first housing to the first inner cavity, and another segment runs through the second housing to the second inner cavity. The limiting member creates a dedicated trough that separates the conducting wire from the rotation joint, allowing the wire to be protected from the harmful rotational forces while maintaining electrical connectivity between components.
Solution Approach 2:
The limiting member acts as an intermediary structure that introduces a conducting wire trough. This trough serves as a protective intermediary that guides and protects the conducting wire from the mechanical stress of rotation at the joint part, thereby preventing wire fracture while maintaining electrical connection.
2Ease of operation
If the conducting wire is allowed to move freely during rotation, then the glasses leg can rotate smoothly, but the conducting wire is prone to upwarp and fracture
Solution Approach 1:
The limiting member creates a trough structure that provides flexible guidance for the conducting wire. The trough confines the wire in a protected path that accommodates rotation while preventing harmful movements such as upwarping. This structure allows smooth rotation of the glasses leg while maintaining wire integrity through the confined routing path.
3Strength
If the conducting wire is protected from rotation, then fracture is prevented, but the structure becomes more complex
Solution Approach 1:
The patent merges the limiting member with the housing structures. The first limiting part is fixedly connected to the main part of the second housing, and the second limiting part is rotatably connected to the first housing. This integration combines the protective limiting function with the existing housing and rotation mechanisms, avoiding the need for separate complex protection systems while still providing effective wire protection through the trough structure.
