Wire Harness Member With Apertures And Slits For Heat Not Burn Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved design of smoking substitute systems, particularly heat-not-burn (HT) systems, to enhance user experience and functionality, as existing systems may not fully address the reduction of harmful compounds and odour associated with traditional tobacco smoking.
Innovation Solution
A wire harness member with apertures and slits is used to support wires in a smoking substitute device, preventing short circuits and heat transfer, while allowing for easy assembly and sealing, and is integrated with a heater and power source to facilitate efficient heating of aerosol-forming articles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are routed through the device body without a wire harness member, then device complexity is reduced, but reliability deteriorates due to increased risk of short circuits and heat transfer
Solution Approach 1:
A wire harness member is introduced as an intermediary component between the wires and the device housing. This member includes apertures for wire passage and slits that extend to the edge, creating a protective barrier that prevents direct contact between wires and conductive surfaces, thereby preventing short circuits while maintaining organized wire routing.
Solution Approach 2:
The wire harness member is designed with slits extending to the edge of the body, creating a preliminary protective structure that prevents heat transfer and short circuits before they can occur. The slits allow wires to pass through while the surrounding material provides immediate protection against harmful thermal and electrical contact.
2Reliability
If a wire harness member with slits extending to the edge is used, then reliability improves by preventing short circuits, but ease of manufacture deteriorates due to additional manufacturing steps
Solution Approach 1:
The wire harness member is formed from a flexible material that can be molded or fabricated with precise aperture and slit geometries. By changing the physical parameters of the material and its formation process, the component achieves both electrical isolation functionality and manufacturability through standard flexible circuit or grommet fabrication techniques.
3Object-affected harmful factors
If wires are supported in apertures with slits, then harmful factors are reduced by preventing heat transfer, but device complexity increases due to the wire harness component
Solution Approach 1:
The wire harness member serves as a thermal barrier intermediary between the wires and the device housing. The material of the wire harness member has thermal insulating properties that prevent heat transfer from heating elements to surrounding components, while the aperture and slit design maintains electrical isolation simultaneously.
