Lid Opening Mechanism Cable Routing for Electronic Storage Cases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device storage cases face challenges in accommodating distribution cables between the lid and case body, leading to issues with workability, space requirements, and increased manufacturing costs due to the need for additional components like sleeves and cableveyors.
Innovation Solution
A lid opening/closing mechanism that integrates a first member attachable to the case body for sliding and a second member rotatable and fixed to the lid, with a curved distribution cable held along these members, utilizing a cable holding member and stopper to manage the cable's storage and movement, allowing for compact positioning and improved workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connection lead is hanged down with excess length between the electronic device and the attachment base, then the electronic device and attachment base can rotate, but the connection lead interferes with work when the electronic device is operated and a large space is required
Solution Approach 1:
The patent introduces a cable guide assembly as an intermediary component between the connection lead and the rotating parts. This assembly includes guide grooves and guide members that direct and constrain the cable's movement path, allowing rotation to occur while preventing the cable from interfering with operational work.
Solution Approach 2:
The patent extracts the cable management function from the general space and creates a dedicated cable guide assembly. By separating the cable routing function into a specific structural component with guide grooves and guide members, the cable is contained and directed along a predetermined path, eliminating interference with device operation.
2Adaptability or versatility
If the connection lead is hanged down with excess length, then rotation is enabled, but a large space is required for storing the connection lead making it difficult to downsize the attachment device
Solution Approach 1:
The patent utilizes three-dimensional space efficiently by creating a cable guide assembly with guide grooves that route the cable through multiple dimensions. The cable is directed along a complex 3D path within the attachment base, allowing excess cable length to be accommodated in vertical and lateral directions rather than requiring increased horizontal storage space.
Solution Approach 2:
The cable guide assembly nests the connection lead within its structured guide grooves and channels. The cable is contained within the attachment base's internal geometry, with guide members and grooves creating a nested arrangement that maximizes space utilization and minimizes the overall volume required.
3Ease of operation
If a sleeve and cableveyor are provided where the connection lead hanged down with excess length, then the connection lead can be managed, but manufacturing cost increases due to increase of components
Solution Approach 1:
The patent merges the cable guide, cable storage, and cable protection functions into a single integrated cable guide assembly. The guide grooves, guide members, and structural components are combined into one unified structure that is molded as part of the attachment base, eliminating the need for separate sleeves and cableveyors and reducing the total component count.
Solution Approach 2:
The cable guide assembly serves multiple functions simultaneously: it guides the cable along the correct path, stores excess cable length, protects the cable from damage, and maintains rotation capability. This multi-functional design replaces multiple specialized components with a single universal structure, reducing manufacturing complexity and cost.
4Adaptability or versatility
If a distribution cable is disposed between the case body and the lid to allow parallel movement and rotation, then the lid can be opened and closed, but no structure for accommodating the cable during movement is disclosed
Solution Approach 1:
The patent introduces a cable guide assembly as an intermediary structure between the case body and lid that actively manages the distribution cable during parallel movement and rotation. The guide grooves and guide members in this assembly direct the cable's path, allowing the lid to move freely while preventing cable tangling or damage.

AI summary
A lid opening/closing mechanism, which attaches a lid to an opening of a case body to be openable and closable, and holds a distribution cable electrically connecting the case body and the lid, includes a first member which is attachable to an attachment surface of the case body and slidable along the attachment surface, and a second member of which one side is rotatable and attachable to the first member, and of which another side is fixed to the lid, wherein the distribution cable is curved and held along the first member and the second member.
