Rolling Spring Power Supply System Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power-supplying systems with springs increase in size due to the biasing mechanism, which is inefficient in terms of space utilization.
Innovation Solution
A power-supplying system with a rolling spring that has a first end projecting inwardly and a second end projecting outwardly, where the turning member engages with the spring internally, and a guide member assists in maintaining the initial biasing force without applying a reactive force, using a primary shaft with a locking section and a support with an accommodating member and temporary locking parts to manage the spring's deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is equipped to bias the turning member in a predetermined rotation direction, then the wire harness can be bent in a predetermined direction, but the entire system increases in size
Solution Approach 1:
The rolling spring is positioned inside the turning member, with the first end projecting inwardly to engage with the locking section on the primary shaft. This nested configuration allows the spring to be contained within the existing structural boundaries of the turning member rather than requiring external mounting space, thereby maintaining compact system dimensions while preserving the biasing function.
Solution Approach 2:
The spring's first end projects inwardly along the axial dimension of the primary shaft rather than extending outward radially. This dimensional reorientation allows the spring to engage with the locking section within the axial space already occupied by the turning member structure, effectively utilizing internal volume rather than adding external volume.
2Force
If the spring is positioned externally to bias the turning member, then the biasing force can be applied, but the system becomes more complex and larger
Solution Approach 1:
The rolling spring is integrated with the turning member structure by positioning it inside the turning member and engaging its first end with the locking section on the primary shaft. This merging of the spring into the existing turning member assembly eliminates the need for separate external mounting structures and reduces overall structural complexity while maintaining the biasing force function.
Solution Approach 2:
The spring is nested within the turning member, with its first end engaging the locking section on the primary shaft. This nested arrangement allows the spring to be part of the turning member's internal structure rather than an external add-on, simplifying the overall device architecture.
3Force
If the spring engages with the support structure, then the biasing force can be maintained, but reactive force opposes assembly
Solution Approach 1:
The function of providing initial biasing force is extracted from the support structure and transferred to the rolling spring itself, which is positioned inside the turning member. The spring's first end engages with the locking section on the primary shaft, allowing the spring to maintain the initial biasing force independently without requiring engagement with the support structure, thereby eliminating the reactive force issue during assembly.
Solution Approach 2:
The locking section on the primary shaft serves as an intermediary engagement point between the spring and the turning member structure. This intermediary allows the spring to be positioned and engaged without requiring direct engagement with the support structure, facilitating easier assembly while maintaining the biasing force function.

Function Achieved in This Case
The system effectively restrains size increase while maintaining the initial biasing force, allowing for easier assembly and efficient operation by ensuring the spring's engagement with the locking section without opposing the biasing force, thus optimizing space usage.

AI summary
An objective of the present invention is to provide a power-supplying system that can restrain an increase in size thereof with a spring equipped therewith. A first end of a rolling spring projects inwardly, and a first locking section is formed on a primary shaft of a turning member, the primary shaft being disposed inside the rolling spring so that the turning member can engage with the rolling spring at the inside of the rolling spring, thereby restraining an increase in size thereof.
