Hinged Door Cable Routing via Slide Supporting Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinged door configurations require a large space for an intermediate member to secure cables or hoses between the door main body and door frame, which is not feasible in all structural setups, leading to excessive cable or hose exposure and potential damage.
Innovation Solution
A hinged door design where a cable or hose extends between the door frame and main body with a through hole in the door main body and a corresponding frame opening portion in the door frame, supported by a slide supporting member that slides relative to the frame opening portion, eliminating the need for an intermediate member and reducing exposed length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an intermediate member (connecting body) is provided between the door main body and door frame to secure the cable, then the cable is protected and exposed length is reduced, but a large space is required between the door main body and door frame which cannot be secured due to structural limitations
Solution Approach 1:
The patent introduces a cable guide member as an intermediary component that is attached to the door frame portion and guides the cable from the door main body. This mediator allows the cable to be securely routed without requiring a large intermediate space, as the cable guide member extends from the door frame toward the door main body and provides a guided path for the cable, eliminating the need for excessive spacing while maintaining cable protection.
Solution Approach 2:
The patent changes the spatial arrangement by having the cable guide member extend in a direction from the door frame toward the door main body, and having the cable pass through or along this guide member. This dimensional reconfiguration allows the cable routing to occur in a different spatial dimension, reducing the required gap between door components while still providing adequate cable guidance and protection.
2Reliability
If the cable is secured between the door main body and door frame using conventional methods, then the cable can be protected, but the exposed cable length becomes large which makes the cable vulnerable to damage by human acts
Solution Approach 1:
The cable guide member serves as a mediator that secures the cable between the door frame and door main body, providing continuous guidance and protection along the cable's path. This intermediary structure prevents the cable from being exposed and vulnerable to external damage, while maintaining secure attachment points at both the door frame and door main body.
3Area of stationary object
If no intermediate member is provided, then the space requirement is eliminated, but the cable or hose becomes exposed and vulnerable to damage
Solution Approach 1:
The cable guide member acts as a minimal-space intermediary that provides cable protection without requiring a large intermediate space. By attaching the guide member to the door frame and having it extend toward the door main body, the patent achieves cable security with minimal spatial requirement, avoiding the need for a bulky intermediate member while still preventing cable exposure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration minimizes the length of the cable or hose exposed between the door main body and door frame, preventing damage and enhancing properties like waterproofing, airtightness, and soundproofing by eliminating the need for an intermediate member, while allowing for a thicker cable or hose.
Implementation Method 1
a slide supporting member supporting the cable or the hose extending through the frame opening portion while sliding relative to the frame opening portion

AI summary
A door main body includes a through hole formed on an end surface located at an end of the door main body in a rotation axis direction of rotation of the door main body, a cable or a hose being inserted through the through hole. A door frame portion includes: a frame opening portion which is formed on a surface opposed to the through hole and has a shape corresponding to a movement trajectory of the through hole when the door main body is opened or closed; and a slide supporting member supporting the cable or the hose extending through the frame opening portion while sliding relative to the frame opening portion.
