Dual-Axis Lid Hinge Wiring for Double-Opening Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In double opening storage devices, the wiring connecting a heater to a power supply is hindered when the lid member rotates around two rotation shafts, preventing smooth operation of the lid member.
Innovation Solution
A wiring member is configured to extend along a hinge member between the two ends of the open/close mechanism, allowing the lid member to rotate freely around both rotation shafts while maintaining a connection to the actuation device, ensuring the wiring does not break during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wire connecting the heater to the power supply device is drawn directly from the support member side to the box body side, then the wiring is simplified, but the lid member is hindered from rotating around the other rotation shaft
Solution Approach 1:
The hinge member serves as an intermediary component that the wiring member extends along. This allows the wiring to be routed through the hinge member's path rather than directly from the support member, enabling the lid to rotate freely around both rotation shafts while maintaining electrical connection to the heater on the lid member
2Ease of operation
If the wiring member is routed to allow free rotation around both rotation shafts, then the lid member operation is improved, but the wiring complexity increases
Solution Approach 1:
The hinge member performs multiple functions: it provides the mechanical linkage for the open/close mechanism and simultaneously serves as a guide path for the wiring member. This multi-functionality allows the wiring to accommodate the dual rotation shaft mechanism without requiring separate routing paths, reducing overall system complexity

AI summary
A double opening storage device includes: a box body; a lid member; an open/close mechanism for opening/closing the lid member around a first or second rotation shaft; and an actuation device provided at the lid member and receiving power from the box body side via a wiring member. The open/close mechanism has a hinge member having one end supported swingably around the first rotation shaft by the lid member and another end supported swingably around the second rotation shaft by the box body. In opening/closing the lid member around the first rotation shaft, the hinge member stays at the box body without following the lid member, and in opening/closing the lid member around the second rotation shaft, the hinge member swings from the box body, following the lid member. The wiring member has a hinge wiring portion extending and wired along the hinge member between the one and other ends.
