Solar Panel Mounting Structure for Electronic Timepiece
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as electronic timepieces, face challenges in efficiently arranging solar panels to receive sufficient light while avoiding interference with other components, which can lead to damage or malfunction.
Innovation Solution
The electronic device incorporates a base with a base mounting part and an outer peripheral side mounting part, an outer peripheral frame, and a pressing member that exerts a restoring force. This configuration allows the solar panel to be securely positioned and pressed against the outer peripheral frame, ensuring optimal light reception and preventing interference with other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the solar panel is arranged to receive sufficient light, then the power generation efficiency is improved, but the solar panel may interfere with surrounding members causing damage or malfunction
Solution Approach 1:
The patent positions the solar panel at a different vertical level (higher or lower) than the calendar disk by providing mounting parts at different heights. This spatial arrangement in the vertical dimension allows the solar panel to receive sufficient light without interfering with the calendar disk and other surrounding members, thus resolving the contradiction between power generation efficiency and reliability
Solution Approach 2:
The patent introduces a pressing member as an intermediary component that secures the solar panel at a predetermined position. This pressing member acts as a mediator between the solar panel and the mounting structure, ensuring the solar panel maintains optimal positioning for light reception while preventing contact with surrounding members, thereby resolving the interference issue
2Reliability
If the solar panel is locked in a predetermined position to prevent interference, then the reliability is improved, but the design flexibility is reduced
Solution Approach 1:
The base structure is designed with multiple mounting parts that can accommodate the solar panel at different vertical levels (higher or lower than the calendar disk). This universal mounting structure provides predetermined positioning to prevent interference while maintaining design flexibility, as the same base can adapt to different solar panel configurations without requiring separate locking mechanisms for each position
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 solution enables the solar panel to be reliably positioned at either a higher or lower level than the calendar disk, ensuring efficient light reception and preventing interference, thus enhancing the device's operational stability and design flexibility.
Implementation Method 1
an electronic device such as an electronic timepiece including a solar panel (solar cell) that generates electricity by receiving light
Implementation Method 2
a pressing member that penetrates the base in a thickness direction and includes an end portion on an upper side in the thickness direction facing the outer peripheral frame and exerting a restoring force upward in the thickness direction

AI summary
Disclosed is an electronic device, including: a base including: a base mounting part; and an outer peripheral side mounting part provided around and at a higher level than the base mounting part; an outer peripheral frame disposed along at least a portion of the outer peripheral side mounting part; and a pressing member that penetrates the base in a thickness direction and includes an end portion on an upper side in the thickness direction facing the outer peripheral frame and exerting a restoring force upward in the thickness direction. When an annular solar panel is disposed on the base mounting part, the pressing member indirectly presses the solar panel against the outer peripheral frame. When at least a portion of a circular solar panel is disposed on the outer peripheral side mounting part, the pressing member directly presses the solar panel against the outer peripheral frame.
